2015-10-22Add "-z call-nop=PADDING" option to ldH.J. Lu3-5/+25
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.

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.

2015-10-05Don't re-export common symbolsH.J. Lu2-1/+7
For ELF linker, a common symbol isn't a definition. When we decide if a symbol should be re-exported, we should check if the symbol isn't undefined, not if it is a definition. bfd/ PR ld/18914 * elflink.c (elf_link_add_object_symbols): Don't re-export a symbol if it isn't undefined. ld/testsuite/ PR ld/18914 * ld-elf/exclude.exp: Also check exclude_common. * ld-elf/exclude2.s: Add exclude_common.
