Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in

(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.

and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and

* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in

following:

Functions named elf_i386_* are called by external routines, other

|
|
|
|
|
in this file more or less in the order in which they are called

|
|
from external routines. eg. elf_i386_check_relocs is called
|

early in the link process, elf_i386_finish_dynamic_sections is
|
|
|

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

link_hash_copy_indirect and symbol flags
A while ago HJ fixed PR ld/18720 with commit 6e33951ed, which, among
other things, modified _bfd_elf_link_hash_copy_indirect to not copy
ref_dynamic, ref_regular, ref_regular_nonweak, non_got_ref, needs_plt
and pointer_equality_needed when setting up an indirect non-versioned
symbol pointing to a non-default versioned symbol. I didn't notice at
the time, but the pr18720 testcase fails on hppa-linux with
"internal error, aborting at binutils-gdb-2.28/bfd/elf32-hppa.c:3933
in elf32_hppa_relocate_section".
Now hppa-linux creates entries in the plt even for local functions, if
they are referenced using plabel (function pointer) relocations. So
needs_plt is set for foo when processing pr18720a.o. When the aliases
in pr28720b.o are processed, we get an indirection from foo to
foo@FOO, but don't copy needs_plt. Since foo@FOO is the "real" symbol
that is used after that point, no plt entry is made for foo and we
bomb when relocating the plabel.
As shown by the hppa-linux scenario, needs_plt should be copied even
for non-default versioned symbols. I believe all of the others ought
to be copied too, with the exception of ref_dynamic. Not copying
ref_dynamic is right because if a shared lib references "foo" it
should not be satisfied by any non-default version "foo@FOO".
* elflink.c (_bfd_elf_link_hash_copy_indirect): Only omit
copying one flag, ref_dynamic, when versioned_hidden.
* elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise.
* elf32-hppa.c (elf32_hppa_copy_indirect_symbol): Use same
logic for copying weakdef flags. Copy plabel flag and merge
tls_type.

for copying weakdef flags.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/
* bfd/aoutx.h: Replace shared, executable, relocatable and pie
fields with bfd_link_executable, bfd_link_dll,
bfd_link_relocatable, bfd_link_pic and bfd_link_pie.

possible that DEF_REGULAR is not set now but will be set

DEF_REGULAR may be cleared later by a strong definition in

|
storing information in the relocs_copied field of the hash

table entry. A similar situation occurs when creating
|

shared libraries and symbol visibility changes render the

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/
* bfd/aoutx.h: Replace shared, executable, relocatable and pie
fields with bfd_link_executable, bfd_link_dll,
bfd_link_relocatable, bfd_link_pic and bfd_link_pie.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the

o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files

o file_ptr becomes a bfd_signed_vma. Besides matching sizes with

it easier for bfd to support a 64 bit off_t on 32 bit hosts that

segfault. However, you won't be able to create an ELFNN binary

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
to gas and ld. It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)]. We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax". With the locally defined symbol, foo,
we convert
mov foo@GOT[(%reg1)], %reg2
to
lea foo[@GOTOFF(%reg1)], %reg2
and convert
call/jmp *foo@GOT[(%reg)]
to
nop call foo/jmp foo nop
When PIC is false, convert
test %reg1, foo@GOT[(%reg2)]
to
test $foo, %reg1
and convert
binop foo@GOT[(%reg1)], %reg2
to
binop $foo, %reg2
where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/

fields with bfd_link_executable, bfd_link_dll,
bfd_link_relocatable, bfd_link_pic and bfd_link_pie.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr

Support i386 TLS code sequences without PLT
We can generate i386 TLS code sequences for general and local dynamic
models without PLT, which uses indirect call via GOT:
call *___tls_get_addr@GOT(%reg)
where EBX register isn't required as GOT base, instead of direct call:
call ___tls_get_addr[@PLT]
which requires EBX register as GOT base.
Since direct call is 4-byte long and indirect call, is 5-byte long, the
extra one byte must be handled properly.
For general dynamic model, 7-byte lea instruction before call instruction
is replaced by 6-byte one to make room for indirect call. For local
dynamic model, we simply use 5-byte indirect call.
TLS linker optimization is updated to recognize new instruction patterns.
For local dynamic model to local exec model transition, we generate
a 6-byte lea instruction as nop, instead of a 1-byte nop plus a 4-byte
lea instruction. Since linker may convert
call ___tls_get_addr[@PLT]
to
addr32 call ____tls_get_addr
when producing static executable, both patterns are recognized.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/

Return void from linker callbacks
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead. What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".
This patch removes the status return on the callbacks that always
return true. I kept the return status for "notice" because that one
does happen to need to return "out of memory".

* bfdlink.h (struct bfd_link_callbacks): Update comments.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

* section.c (struct sec): Rename "_cooked_size" to "size".
Rename "_raw_size" to "rawsize".
(STD_SECTION): Adjust comments.
(bfd_set_section_size, bfd_get_section_contents): Use size.
(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/
* bfd/aoutx.h: Replace shared, executable, relocatable and pie
fields with bfd_link_executable, bfd_link_dll,
bfd_link_relocatable, bfd_link_pic and bfd_link_pie.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/

fields with bfd_link_executable, bfd_link_dll,

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.
