H.J. Lu	d3d9c95aef	Support PLT and GOT references in local PIC check 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".	11 years ago
H.J. Lu	9637d8a253	Extend local PLT reference check 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.	11 years ago
Alan Modra	a0af371c25	Fix localplt test breakage with new readelf 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.	11 years ago
Adhemerval Zanella	7bc5a74162	Fix localplt check for GNU_IFUNC 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.	12 years ago
Roland McGrath	90fe4186b3	Do check-localplt test using readelf rather than a build-time C program.	14 years ago
