H.J. Lu 7b7e7f1da2 Check symbol defined by assignment in linker script
Symbol symbol defined by an assignment in a linker script has type
bfd_link_hash_new.  elf_i386_convert_load and elf_x86_64_convert_load
should check bfd_link_hash_new to see if a symbol is defined by a linker
script.

H.J. Lu a6af384b19 Properly convert address load of __start_XXX/__stop_XXX
Since __start_XXX and __stop_XXX symbols aren't defined when address
load is being converted, we need to check if there is an XXX output
section to get their section and value.  This patch adds a new function,
bfd_link_get_defined_symbol, to search for the XXX output section to
check if __start_XXX and __stop_XXX symbols are defined.

H.J. Lu caa65211bb Add "-z call-nop=PADDING" option to ld
The ld linker can transform indirect call to a locally defined function,
foo, via its GOT slot, to either "NOP call foo" or "call foo NOP" where
NOP is a 1-byte NOP padding.  This patch adds a "-z call-nop=PADDING"
option to x86 ld to control 1-byte NOP padding for x86 call instruction.
PADDING is one of prefix-addr, prefix-nop, suffix-nop, prefix-NUMBER or
suffix-NUMBER.

R_X86_64_REX_GOTPCRELX relocations proposed in

to gas and ld.  It updates gas to generate R_X86_64_GOTPCRELX,

H.J. Lu 02a866936d 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

Andreas Krebbel 01a5358479 S/390: ifunc: Handle GOTOFF relocs on ifunc symbols.
Normally a GOTOFF reloc only uses the GOT pointer to address something
relativ to it without actually requiring a GOT or PLT slot.  Things
change if the target is an ifunc symbol though.

bfd/ChangeLog:

	* elf32-s390.c (elf_s390_check_relocs): Fallthrough to the PLT
	slot allocating code for GOTOFF relocs on ifunc symbols.
	(elf_s390_gc_sweep_hook): Decrement plt refcount for GOTOFF relocs
	on ifunc symbols.

H.J. Lu c8b187ea07 Use bfd_get_32 and bfd_put_32 to access ch_type
The ch_type field in Elf64_External_Chdr is 4 bytes.  We should use
bfd_get_32 and bfd_put_32 to access it.

	* bfd.c (bfd_update_compression_header): Use bfd_put_32 on
	ch_type.
	(bfd_check_compression_header): Use bfd_get_32 on ch_type.
	(bfd_convert_section_contents): Use bfd_get_32 and bfd_put_32
	on ch_type.
