From: Hongyu Wang <hongyuw@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r14-5749] [APX PUSH2POP2] Adjust operand order for PUSH2POP2 Date: Wed, 22 Nov 2023 07:40:55 +0000 (GMT) [thread overview] Message-ID: <20231122074055.5A6FC38582A4@sourceware.org> (raw) https://gcc.gnu.org/g:bd17d00a4bdee34876cc97bdf9a1f2316e0a6790 commit r14-5749-gbd17d00a4bdee34876cc97bdf9a1f2316e0a6790 Author: Hongyu Wang <hongyu.wang@intel.com> Date: Fri Nov 17 15:30:16 2023 +0800 [APX PUSH2POP2] Adjust operand order for PUSH2POP2 The push2/pop2 operand order does not match the binutils implementation for AT&T syntax that it will first push operands[2] then operands[1]. Correct it by reverse operand order for AT&T syntax. gcc/ChangeLog: * config/i386/i386.md (push2_di): Adjust operand order for AT&T syntax. (pop2_di): Likewise. (push2p_di): Likewise. (pop2p_di): Likewise. gcc/testsuite/ChangeLog: * gcc.target/i386/apx-push2pop2-1.c: Adjust output scan. * gcc.target/i386/apx-push2pop2_force_drap-1.c: Likewise.
