This reverts the below commit to not generate PLT32 relocs on branches by default. Used for old distros to not have to update several packages/tools that can't handle them. I.e. a compatibility patch. The changes in nop-[345].d and pr22842b.S are followups to not break the testsuite because of this revert. commit bd7ab16b4537788ad53521c45469a1bdae84ad4a Author: H.J. Lu <hjl.tools@gmail.com> Date: Tue Feb 13 07:34:22 2018 -0800 x86-64: Generate branch with PLT32 relocation Since there is no need to prepare for PLT branch on x86-64, generate R_X86_64_PLT32, instead of R_X86_64_PC32, if possible, which can be used as a marker for 32-bit PC-relative branches. To compile Linux kernel, this patch: From: "H.J. Lu" <hjl.tools@gmail.com> Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32 On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared objects must use PIC PLT. To use PIC PLT, you need to load _GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on x86-64 since x86-64 uses PC-relative PLT. On x86-64, for 32-bit PC-relative branches, we can generate PLT32 relocation, instead of PC32 relocation, which can also be used as a marker for 32-bit PC-relative branches. Linker can always reduce PLT32 relocation to PC32 if function is defined locally. Local functions should use PC32 relocation. As far as Linux kernel is concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32 since Linux kernel doesn't use PLT. is needed.
