Lu <hjl.to...@gmail.com> Date: Thu May 22 11:29:49 2025 +0800 x86: Check MODRM for call and jmp in binutils older than 2.45 When i386 glibc was assembled with commit: commit 11c2852449825a5f486f63bc40aabed56b7c04c1 (HEAD) Author: Jan Beulich <jbeul...@suse.com> Date: Fri Feb 21 10:24:50 2025 +0100 x86: widen @got{,pcrel} support to PUSH and APX IMUL With us doing the transformation to an immediate operand for MOV and various ALU insns, there's little reason to then not support the same conversion for the other two insns which have respective immediate operand forms. Unfortunately for IMUL (due to the 0F opcode prefix) there's no suitable relocation, so the pre-APX forms cannot be marked for relaxation in the assembler. "pushl main@GOT(%ebx)" in sysdeps/i386/start.S was assembled to 1c: ff b3 00 00 00 00 push 0x0(%ebx) 1e: R_386_GOT32X main Linkers in binutils versions older than 2.45 treated it as jmp and relaxed it to 22c: e9 cf ff ff ff jmp 200 <main> 231: 90 nop Update elf_i386_convert_load_reloc in binutils versions older than 2.45 to check MODRM for call and jmp to work with i386 glibc assembled with binutils 2.45 or newer. Do the same in elf_x86_64_convert_load_reloc. PR ld/32991 * elf32-i386.c (elf_i386_convert_load_reloc): Check MODRM for call and jmp. * elf64-x86-64.c (elf_x86_64_convert_load_reloc): Likewise.
