--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Uros Bizjak <u...@gcc.gnu.org>: https://gcc.gnu.org/g:267dbd42f42c52a515f49c0875d296a9cf5988fe commit r12-1318-g267dbd42f42c52a515f49c0875d296a9cf5988fe Author: Uros Bizjak <ubiz...@gmail.com> Date: Wed Jun 9 09:46:00 2021 +0200 i386: Do not emit segment overrides for %p and %P [PR100936] Using %p to move the address of a symbol using LEA: asm ("lea %p1, %0" : "=r"(addr) : "m"(var)); emits assembler warning when VAR is declared in a non-generic address space: Warning: segment override on `lea' is ineffectual The problem is with %p operand modifier, which should emit raw symbol name: p -- print raw symbol name. Similar problem exists with %P modifier, trying to CALL or JMP to an overridden symbol,e.g: call %gs:zzz jmp %gs:zzz emits assembler warning: Warning: skipping prefixes on `call' Warning: skipping prefixes on `jmp' Ensure that %p and %P never emit segment overrides. 2021-06-08 Uroš Bizjak <ubiz...@gmail.com> gcc/ PR target/100936 * config/i386/i386.c (print_operand_address_as): Rename "no_rip" argument to "raw". Do not emit segment overrides when "raw" is true. gcc/testsuite/ PR target/100936 * gcc.target/i386/pr100936.c: New test.
