* Support PLT and GOT references in local PIC checkH.J. Lu2015-10-141-1/+1
| | | | | | | | | | | | | | Linker in binutils 2.26 and newer generate GOT references instead PLT references when -z now is passed to linker. We need to extend scripts/localplt.awk to allow PLT or GOT references. [BZ #19007] * scripts/localplt.awk: Also allow GOT references. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark _Unwind_Find_FDE, calloc, memalign, realloc and __libc_memalign with "+ REL R_386_GLOB_DAT". * sysdeps/x86_64/localplt.data: Mark calloc, memalign, realloc and __libc_memalign with "+ RELA R_X86_64_GLOB_DAT".
* Extend local PLT reference checkH.J. Lu2015-07-291-0/+47
| | | | | | | | | | | | | | On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with R_*_GLOB_DAT relocation against the same symbol. This patch extends local PLT reference check to support alternate relocations. [BZ #18078] * scripts/check-localplt.awk: Support alternate relocations. * scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL sections. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and malloc entries with + REL R_386_GLOB_DAT. * sysdeps/x86_64/localplt.data: New file.
* Fix localplt test breakage with new readelfAlan Modra2015-03-031-2/+2
| | | | | | | | | Since 2014-11-24 binutils git commit bb4d2ac2, readelf has appended the symbol version to symbols shown in reloc dumps. [BZ #16512] * scripts/localplt.awk: Strip off symbol version. * NEWS: Mention bug fix.
* Fix localplt check for GNU_IFUNCAdhemerval Zanella2014-03-251-2/+8
| | | | | | | | GNU_IFUNC are shown by readelf in 'Relocation section' value as "symbol()" instead of expected hexadecimal value. This causes the check-localplt script to ignore potential PLT stub begin generated by wrong IFUNC usage. This patch changes the localplt script to emit such PLT cases.
* Do check-localplt test using readelf rather than a build-time C program.Roland McGrath2012-05-011-0/+59
