x86: Properly handle PLT expression in directive
For PLT expressions, we should subtract the PLT relocation size only for jump instructions. Since PLT relocations are PC relative, we only allow "symbol@PLT" in PLT expression. gas/ PR gas/23997 * config/tc-i386.c (x86_cons): Check for invalid PLT expression. (md_apply_fix): Subtract the PLT relocation size only for jump instructions. * testsuite/gas/i386/reloc32.s: Add test for invalid PLT expression. * testsuite/gas/i386/reloc64.s: Likewise. * testsuite/gas/i386/ilp32/reloc64.s: Likewise. * testsuite/gas/i386/reloc32.l: Updated. * testsuite/gas/i386/reloc64.l: Likewise. * testsuite/gas/i386/ilp32/reloc64.l: Likewise. ld/ PR gas/23997 * testsuite/ld-i386/i386.exp: Run PR gas/23997 test. * testsuite/ld-x86-64/x86-64.exp: Likewise. * testsuite/ld-x86-64/pr23997a.s: New file. * testsuite/ld-x86-64/pr23997b.c: Likewise. * testsuite/ld-x86-64/pr23997c.c: Likewise.
