2014-11-20Always load function pointer into a stack variableH.J. Lu1-2/+11
This patch makes sure that compiler won't optimize out loading function into a stack variable. * ld-ifunc/ifunc-main.c (get_bar): New function. (main): Use it.

2014-11-20Run IFUNC run-time tests only if IFUNC is supportedH.J. Lu1-7/+15
* lib/ld-lib.exp (check_ifunc_available): New. * ld-ifunc/ifunc.exp: Run IFUNC run-time tests only if IFUNC is supported.
2014-07-16Properly match PLT entry against .got.plt relocationH.J. Lu3-0/+121
Relocations against .got.plt section may not be in the same order as entries in PLT section. It is incorrect to assume that the Ith reloction index against .got.plt section always maps to the (I + 1)th entry in PLT section. This patch matches the .got.plt relocation offset/index in PLT entry against the index in .got.plt relocation table. It only checks R_*_JUMP_SLOT and R_*_IRELATIVE relocations. It ignores R_*_TLS_DESC and R_*_TLSDESC relocations since they have different PLT entries. bfd/ PR binutils/17154 * elf32-i386.c (elf_i386_plt_sym_val): Only match R_*_JUMP_SLOT and R_*_IRELATIVE relocation offset with PLT entry. * elf64-x86-64.c (elf_x86_64_plt_sym_val): Likewise.

2014-01-21Check incompatible existing default symbol definitionH.J. Lu8-0/+76
After resolving a versioned reference, foo@VER1, to a default versioned definition, foo@@VER1, from a shared object, we also merge it with the existing regular default symbol definition, foo. When foo is IFUNC and foo@@VER1 aren't, we will merge 2 incompatible definitions. This patch avoids merging foo@@VER1 definition with foo definition if one is IFUNC and the other isn't.
2013-11-04Allow for extra st_other readelf output in ld testsuiteAlan Modra1-1/+2
On PowerPC64 ELFv2 readelf emits [<localentry>: 8] describing extra symbol st_other bits. * ld-elfvers/vers24.rd: Allow extra readelf output after symbol visibility. * ld-ifunc/ifunc.exp: Likewise.

2013-04-15Check regular reference without non-GOT referenceH.J. Lu3-0/+42
non_got_ref may not be set when building shared library. We need to set non_got_ref if there are any non-PIC relocations. But we only did this when there were no PLT/GOT relocations.
