From b1ec623ed50bb8c7b9b6333fa350c3866dbde87f Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 16 Mar 2021 07:41:46 -0700 Subject: x86_64: Correct THREAD_SETMEM/THREAD_SETMEM_NC for movq [BZ #27591] config/i386/constraints.md in GCC has (define_constraint "e" "32-bit signed integer constant, or a symbolic reference known to fit that range (for immediate operands in sign-extending x86-64 instructions)." (match_operand 0 "x86_64_immediate_operand")) Since movq takes a signed 32-bit immediate or a register source operand, use "er", instead of "nr"/"ir", constraint for 32-bit signed integer constant or register on movq.
