H.J. Lu	02e2aef89b	Optimize R_386_GOT32/R_386_GOT32X only if addend is 0 Linker can't optimize R_386_GOT32 and R_386_GOT32X relocations if addend isn't 0. It isn't valid to convert movl foo@GOT+1(%ecx), %eax to leal foo@GOTOFF+1(%ecx), %eax nor to convert movq foo@GOTPCREL+1(%rip), %rax to leaq foo(%rip), %rax for x86-64. We should check if addend is 0 before optimizing R_386_GOT32 and R_386_GOT32X relocations. Testcases are added for i386 and x86-64. bfd/ * elf32-i386.c (elf_i386_convert_load): Skip if addend isn't 0.

Alan Modra	923b198a84	addr2line vs. inlined C functions called from C++ In this case the inlined function doesn't have DW_AT_linkage_name in .debug_info, but the language is C++ so find_nearest_line goes looking in the symbol table. Since the function is inlined the enclosing non-inline function symbol is returned from _bfd_elf_find_function, which is wrong. This patch only uses a symbol if its address matches.

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 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.
