From 6c6f96040a13e3403a418803cd9f539701c4c00e Mon Sep 17 00:00:00 2001 From: Jin Ma Date: Wed, 17 May 2023 15:48:39 -0600 Subject: [PATCH] Fix type error of 'switch (SUBREG_BYTE (op)).' For example: (define_insn "mov_lowpart_sidi2" [(set (match_operand:SI 0 "register_operand" "=r") (subreg:SI (match_operand:DI 1 "register_operand" " r") 0))] "TARGET_64BIT" "mov\t%0,%1") (define_insn "mov_highpart_sidi2" [(set (match_operand:SI 0 "register_operand" "=r") (subreg:SI (match_operand:DI 1 "register_operand" " r") 1))] "TARGET_64BIT" "movh\t%0,%1") When defining the above patterns, the generated file insn-recog.cc will appear 'switch (SUBREG_BYTE (op))', but since the return value of SUBREG_BYTE is poly_uint16_pod, the following error will occur: "error: switch quantity not an integer". gcc/ChangeLog: * genrecog.cc (print_nonbool_test): Fix type error of switch (SUBREG_BYTE (op))'. --- gcc/genrecog.cc | 1 + 1 file changed, 1 insertion(+) diff --git a/gcc/genrecog.cc b/gcc/genrecog.cc index 6dd375da5e35..04a5533ca4b2 100644 --- a/gcc/genrecog.cc +++ b/gcc/genrecog.cc @@ -4619,6 +4619,7 @@ print_nonbool_test (output_state *os, const rtx_test &test) printf ("SUBREG_BYTE ("); print_test_rtx (os, test); printf (")"); + printf (".to_constant ()"); break; case rtx_test::WIDE_INT_FIELD: -- 2.47.2
