From 6f93a7c7fc62b2d6ab47e5d5eb60d41366e1ee9e Mon Sep 17 00:00:00 2001 From: Christophe Lyon Date: Tue, 30 Mar 2021 12:26:33 +0000 Subject: [PATCH] arm: Fix emission of Tag_ABI_VFP_args with MVE and -mfloat-abi=hard (PR target/99773) When compiling with -mfloat-abi=hard -march=armv8.1-m.main+mve, we want to emit Tag_ABI_VFP_args even though we are not emitting floating-point instructions (we need "+mve.fp" for that), because we use MVE registers to pass FP arguments. This patch removes the condition on (! TARGET_SOFT_FLOAT) because this is a case where TARGET_SOFT_FLOAT is true, and TARGET_HARD_FLOAT_ABI is true too. 2021-03-30 Richard Earnshaw gcc/ PR target/99773 * config/arm/arm.c (arm_file_start): Fix emission of Tag_ABI_VFP_args attribute. --- gcc/config/arm/arm.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) diff --git a/gcc/config/arm/arm.c b/gcc/config/arm/arm.c index e89f5e2..518bfed 100644 --- a/gcc/config/arm/arm.c +++ b/gcc/config/arm/arm.c @@ -28150,14 +28150,11 @@ arm_file_start (void) if (print_tune_info) arm_print_tune_info (); - if (!
