2015-10-26Check symbol defined by assignment in linker scriptH.J. Lu9-0/+72
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. bfd/ PR ld/19175 * elf32-i386.c (elf_i386_convert_load): Check bfd_link_hash_new instead of calling bfd_link_get_defined_symbol. * elf64-x86-64.c (elf_x86_64_convert_load): Likewise.

2015-10-26Properly convert address load of __start_XXX/__stop_XXXH.J. Lu20-0/+70
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.

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. Lu36-5/+519
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.

2015-09-29Adjust the output section size to skip gap fillsH.J. Lu4-0/+34
In objcopy, copy_object calls copy_section to copy contents of input section to output section. When --gap-fill= is used, objcopy extends the size of output sectios to fill gaps between output sections with gap fills. In this case, we adjust the output section size to skip gap files to avoid reading beypond the input section buffer before calling copy_section and restore the output section size after input sections have been copied. binutils/ PR binutils/19005 * objcopy.c (copy_object): Adjust the output section size to skip gap fills between sections when copying from input sections to output sections. ld/testsuite/ PR binutils/19005 * ld-elf/pr19005.d: New file. * ld-elf/pr19005.s: Likewise. * ld-elf/pr19005.t: Likewise.

This fixes two problems. First, the --sysroot option wasn't available with a ld configured without --with-sysroot, a historical accident.
