- Subject: [PATCH] opcodes: fix -std=gnu23 compatibility wrt static_assert
- static_assert is declared in C23 so we can't reuse that identifier:
- * Define our own static_assert conditionally;
- * Rename "static assert" hacks to _N as we do already in some places
- to avoid a conflict.
- ChangeLog:
- PR ld/32372
- * i386-gen.c (static_assert): Define conditionally.
- * mips-formats.h (MAPPED_INT): Rename identifier.
- (MAPPED_REG): Rename identifier.
- (OPTIONAL_MAPPED_REG): Rename identifier.
- * s390-opc.c (static_assert): Define conditionally.
