Overview:
|
|
|
|
|
|
|
|
The implementation currently supports both traditional TLS and TLS
|
|
|
|
descriptors, but only general dynamic (GD).

For traditional TLS the assembler will present us with code

BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

blr x1 R_AARCH64_TLSDESC_CALL(foo)
|
2012-08-13 16:52:54 +02:00
|
|
|
|
|
|
|
The relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} against foo
|
|
|
|
indicate that foo is thread local and should be accessed via the
|
|
|
|
traditional TLS mechanims.

The relocations R_AARCH64_TLSDESC_{ADR_PAGE21,LD64_LO12_NC,ADD_LO12_NC}
|
2012-08-13 16:52:54 +02:00
|
|
|
against foo indicate that 'foo' is thread local and should be accessed
|
|
|
|
via a TLS descriptor mechanism.
|
|
|
|
|
|
|
|
The precise instruction sequence is only relevant from the
|
|
|
|
perspective of linker relaxation which is currently not implemented.
|
|
|
|
|
|
|
|
The static linker must detect that 'foo' is a TLS object and
|
|
|
|
allocate a double GOT entry. The GOT entry must be created for both
|
|
|
|
global and local TLS symbols. Note that this is different to none
|
|
|
|
TLS local objects which do not need a GOT entry.
|
|
|
|
|
|
|
|
In the traditional TLS mechanism, the double GOT entry is used to
|
|
|
|
provide the tls_index structure, containing module and offset
|
2013-06-26 12:47:06 +02:00
|
|
|
entries. The static linker places the relocation R_AARCH64_TLS_DTPMOD
|
2012-08-13 16:52:54 +02:00
|
|
|
on the module entry. The loader will subsequently fixup this
|
|
|
|
relocation with the module identity.
|
|
|
|
|
|
|
|
For global traditional TLS symbols the static linker places an
|
2013-06-26 12:47:06 +02:00
|
|
|
R_AARCH64_TLS_DTPREL relocation on the offset entry. The loader
|
2012-08-13 16:52:54 +02:00
|
|
|
will subsequently fixup the offset. For local TLS symbols the static
|
|
|
|
linker fixes up offset.
|
|
|
|
|
|
|
|
In the TLS descriptor mechanism the double GOT entry is used to
|
|
|
|
provide the descriptor. The static linker places the relocation
|
|
|
|
R_AARCH64_TLSDESC on the first GOT slot. The loader will
|
|
|
|
subsequently fix this up.
|
|
|
|
|
|
|
|
Implementation:
|
|
|
|
|
|
|
|
The handling of TLS symbols is implemented across a number of
|
|
|
|
different backend functions. The following is a top level view of
|
|
|
|
what processing is performed where.
|
|
|
|
|
|
|
|
The TLS implementation maintains state information for each TLS
|
|
|
|
symbol. The state information for local and global symbols is kept
|
|
|
|
in different places. Global symbols use generic BFD structures while
|
|
|
|
local symbols use backend specific structures that are allocated and
|
|
|
|
maintained entirely by the backend.
|
|
|
|
|
|
|
|
The flow:

|
2012-08-13 16:52:54 +02:00
|
|
|
|
|
|
|
This function is invoked for each relocation.
|
|
|
|
|
|
|
|
The TLS relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} and
|
2013-06-26 12:47:06 +02:00
|
|
|
R_AARCH64_TLSDESC_{ADR_PAGE21,LD64_LO12_NC,ADD_LO12_NC} are
|
2012-08-13 16:52:54 +02:00
|
|
|
spotted. One time creation of local symbol data structures are
|
|
|
|
created when the first local symbol is seen.
|
|
|
|
|
|
|
|
The reference count for a symbol is incremented. The GOT type for
|
|
|
|
each symbol is marked as general dynamic.

|
2012-08-13 16:52:54 +02:00
|
|
|
|
|
|
|
For each global with positive reference count we allocate a double
|
|
|
|
GOT slot. For a traditional TLS symbol we allocate space for two
|
|
|
|
relocation entries on the GOT, for a TLS descriptor symbol we
|
|
|
|
allocate space for one relocation on the slot. Record the GOT offset
|
|
|
|
for this symbol.

|
|
Emit the relevant TLS relocations against the GOT for each TLS
|
|
|
|
symbol. For local TLS symbols emit the GOT offset directly. The GOT
|
|
|
|
relocations are emitted once the first time a TLS symbol is
|
|
|
|
encountered. The implementation uses the LSB of the GOT offset to
|
|
|
|
flag that the relevant GOT relocations for a symbol have been
|
|
|
|
emitted. All of the TLS code that uses the GOT offset needs to take
|
|
|
|
care to mask out this flag bit before using the offset.

[GAS][AARCH64]Add group relocations to create PC-relative offset.
This is a patch to add the gas support for group relocations to create a
16, 32, 48, or 64 bit PC-relative offset inline.
The following relocations are added along with the test cases:
BFD_RELOC_AARCH64_MOVW_PREL_G0, BFD_RELOC_AARCH64_MOVW_PREL_G0_NC,
BFD_RELOC_AARCH64_MOVW_PREL_G1, BFD_RELOC_AARCH64_MOVW_PREL_G1_NC,

the problems.

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.

ARM and AArch64 messages
More standarization of error/warning messages. The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop. I've replaced the line breaks with
semicolons.
So for instance the following
system/path/to/ld: myobject.o: invalid special symbol `foo'.
system/path/to/ld: It must be a global or weak function symbol.
becomes
system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol

ARM and AArch64 messages
More standarization of error/warning messages. The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop. I've replaced the line breaks with
semicolons.
So for instance the following
system/path/to/ld: myobject.o: invalid special symbol `foo'.
system/path/to/ld: It must be a global or weak function symbol.
becomes
system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol

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/

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.

ARM and AArch64 messages
More standarization of error/warning messages. The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop. I've replaced the line breaks with
semicolons.
So for instance the following
system/path/to/ld: myobject.o: invalid special symbol `foo'.
system/path/to/ld: It must be a global or weak function symbol.
becomes
system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol

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 whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space

the problems.

BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

ld: aarch64: fix TLS relaxation where TCB_SIZE is used
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for
ilp32. During relaxation, ld goes to do a replace:
bl __tls_get_addr => add R0, R0, TCB_SIZE
But actual implementation is:
bfd_putl32 (0x91004000, contents + rel->r_offset + 4);
Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32.
The possible fix for it is:
bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4);
But ilp32 also needs w-registers, so it's simpler to put proper
instruction in #if/#else condition.
There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new
tests added for ilp32 mode to test it.
Yury
* bfd/elfnn-aarch64.c: fix TLS relaxations for ilp32 where
TCB_SIZE is used.

ld: aarch64: fix TLS relaxation where TCB_SIZE is used
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for
ilp32. During relaxation, ld goes to do a replace:
bl __tls_get_addr => add R0, R0, TCB_SIZE
But actual implementation is:
bfd_putl32 (0x91004000, contents + rel->r_offset + 4);
Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32.
The possible fix for it is:
bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4);
But ilp32 also needs w-registers, so it's simpler to put proper
instruction in #if/#else condition.
There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new
tests added for ilp32 mode to test it.

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".

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.

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".

ARM and AArch64 messages
More standarization of error/warning messages. The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop. I've replaced the line breaks with
semicolons.
So for instance the following

system/path/to/ld: It must be a global or weak function symbol.

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".

readonly_dynrelocs
In early October, HJ Lu added support for a number of targets to "Dump
dynamic relocation in read-only section with minfo". This extends
that support to more targets, displays the symbol involved, and splits
the existing function that sets TEXTREL into a "readonly_dynrelocs"
and "maybe_set_textrel" function. I'll need "readonly_dynrelocs" if I
ever get around to fixing "pr22374 function pointer initialization"
fails.
am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary
needing text relocations with DT_TEXTREL. That's not good. xtensa also
fails to do so but complains about "dangerous relocation: dynamic
relocation in read-only section" so I reckon that is fine and have
marked the test as an xfail. The other targets need maintainer
attention.
Curiously, the map file dump wasn't added for x86, so the map test
currently fail on x86. It also fails on alpha, am33_2.0, arc, bfin,
hppa64, ia64, m68k, mips, mn10300, nios2, score and vax. cris
complains with "tmpdir/textrel.o, section .rodata: relocation
R_CRIS_32 should not be used in a shared object; recompile with -fPIC"
so I've marked it as an xfail.

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.

Delete duplicate target short-cuts to dynamic sections
We'd like to have the elf_link_hash_table srelplt field rather than
some private target field used to save short-cuts to a PLT relocation
section. This save a little space but mainly is so that the generic
ELF code can access the field. Ditto for other dynamic sections.

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.

Merge bfd_find_nearest_line variants
When bfd_find_nearest_line_discriminator was added, not enough care
was taken to ensure all targets had a proper definition of the function.
This patch cures that by merging bfd_find_nearest_line_discriminator
and bfd_find_nearest_line target implementations.

Merge bfd_find_nearest_line variants

Merge bfd_find_nearest_line variants
When bfd_find_nearest_line_discriminator was added, not enough care
was taken to ensure all targets had a proper definition of the function.
This patch cures that by merging bfd_find_nearest_line_discriminator
and bfd_find_nearest_line target implementations.

BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

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.

readonly_dynrelocs
In early October, HJ Lu added support for a number of targets to "Dump
dynamic relocation in read-only section with minfo". This extends
that support to more targets, displays the symbol involved, and splits
the existing function that sets TEXTREL into a "readonly_dynrelocs"
and "maybe_set_textrel" function. I'll need "readonly_dynrelocs" if I
ever get around to fixing "pr22374 function pointer initialization"
fails.
am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary
needing text relocations with DT_TEXTREL. That's not good. xtensa also
fails to do so but complains about "dangerous relocation: dynamic
relocation in read-only section" so I reckon that is fine and have
marked the test as an xfail. The other targets need maintainer
attention.
Curiously, the map file dump wasn't added for x86, so the map test
currently fail on x86. It also fails on alpha, am33_2.0, arc, bfin,
hppa64, ia64, m68k, mips, mn10300, nios2, score and vax. cris
complains with "tmpdir/textrel.o, section .rodata: relocation
R_CRIS_32 should not be used in a shared object; recompile with -fPIC"
so I've marked it as an xfail.

readonly_dynrelocs
In early October, HJ Lu added support for a number of targets to "Dump
dynamic relocation in read-only section with minfo". This extends
that support to more targets, displays the symbol involved, and splits
the existing function that sets TEXTREL into a "readonly_dynrelocs"
and "maybe_set_textrel" function. I'll need "readonly_dynrelocs" if I
ever get around to fixing "pr22374 function pointer initialization"
fails.
am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary
needing text relocations with DT_TEXTREL. That's not good. xtensa also
fails to do so but complains about "dangerous relocation: dynamic
relocation in read-only section" so I reckon that is fine and have
marked the test as an xfail. The other targets need maintainer
attention.
Curiously, the map file dump wasn't added for x86, so the map test
currently fail on x86. It also fails on alpha, am33_2.0, arc, bfin,
hppa64, ia64, m68k, mips, mn10300, nios2, score and vax. cris
complains with "tmpdir/textrel.o, section .rodata: relocation
R_CRIS_32 should not be used in a shared object; recompile with -fPIC"
so I've marked it as an xfail.

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.

Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space

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.

readonly_dynrelocs
In early October, HJ Lu added support for a number of targets to "Dump
dynamic relocation in read-only section with minfo". This extends
that support to more targets, displays the symbol involved, and splits
the existing function that sets TEXTREL into a "readonly_dynrelocs"
and "maybe_set_textrel" function. I'll need "readonly_dynrelocs" if I
ever get around to fixing "pr22374 function pointer initialization"
fails.
am33_2.0, arc, bfin, hppa64, mn10300, and nios2 fail to mark a binary
needing text relocations with DT_TEXTREL. That's not good. xtensa also
fails to do so but complains about "dangerous relocation: dynamic
relocation in read-only section" so I reckon that is fine and have
marked the test as an xfail. The other targets need maintainer
attention.
Curiously, the map file dump wasn't added for x86, so the map test
currently fail on x86. It also fails on alpha, am33_2.0, arc, bfin,
hppa64, ia64, m68k, mips, mn10300, nios2, score and vax. cris
complains with "tmpdir/textrel.o, section .rodata: relocation
R_CRIS_32 should not be used in a shared object; recompile with -fPIC"
so I've marked it as an xfail.

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.

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.

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.

BFD whitespace fixes
Binutils is supposed to use tabs. In my git config I have
whitespace = indent-with-non-tab,space-before-tab,trailing-space
and I got annoyed enough seeing red in "git diff" output to fix
the problems.

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.
