--- Comment #6 from H.J. Lu <hjl.tools at gmail dot com> --- Created attachment 13109 --> https://sourceware.org/bugzilla/attachment.cgi?id=13109&action=edit A patch to generate R_386_PLT32 I tried this patch when I made: commit bd7ab16b4537788ad53521c45469a1bdae84ad4a Author: H.J. Lu <hjl.to...@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.to...@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. and got FAIL: visibility (hidden_normal) (non PIC) FAIL: visibility (hidden_normal) (non PIC, load offset) FAIL: visibility (hidden_normal) (PIC main, non PIC so) FAIL: visibility (hidden_weak) (non PIC) FAIL: visibility (hidden_weak) (non PIC, load offset) FAIL: visibility (hidden_weak) (PIC main, non PIC so) FAIL: visibility (protected) (non PIC) FAIL: visibility (protected) (non PIC, load offset) FAIL: visibility (protected) (PIC main, non PIC so) FAIL: visibility (protected_undef_def) (non PIC) FAIL: visibility (protected_undef_def) (non PIC, load offset) FAIL: visibility (protected_undef_def) (PIC main, non PIC so) FAIL: visibility (protected_weak) (non PIC) FAIL: visibility (protected_weak) (non PIC, load offset) FAIL: visibility (protected_weak) (PIC main, non PIC so) FAIL: visibility (normal) (non PIC) FAIL: visibility (normal) (non PIC, load offset) FAIL: visibility (normal) (PIC main, non PIC so) FAIL: ld-i386/pr19636-2a FAIL: ld-i386/pr19636-2b FAIL: ld-i386/pr19636-2c FAIL: ld-i386/pr19636-2d FAIL: ld-i386/pr19636-2e FAIL: ld-i386/pr20515 FAIL: shared (non PIC) FAIL: shared (non PIC, load offset) FAIL: shared (PIC main, non PIC so) in i386 linker tests. -- You are receiving this mail because: You are on the CC list for the bug.
