2015-10-22Add R_386_GOT32X support to gas and ldH.J. Lu5-45/+336
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. bfd/ * elf32-i386.c: Include opcode/i386.h.

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.
