2020-12-04x86-64: Convert load to mov only for GOTPCRELX relocationsH.J. Lu8-1/+91
Since converting load to mov needs to rewrite the REX byte and we don't know if there is a REX byte with GOTPCREL relocation, do it only for GOTPCRELX relocations. bfd/ PR ld/27016 * elf64-x86-64.c (elf_x86_64_convert_load_reloc): Convert load to mov only for GOTPCRELX relocations. ld/ PR ld/27016 * testsuite/ld-x86-64/x86-64.exp: Run pr27016a and pr27016b. * testsuite/ld-x86-64/pr27016a.d: New file. * testsuite/ld-x86-64/pr27016a.s: Likewise. * testsuite/ld-x86-64/pr27016b.d: Likewise. * testsuite/ld-x86-64/pr27016b.s: Likewise.
