From b2672dd630c81513e08829adc63294ffeedf5693 Mon Sep 17 00:00:00 2001 From: Fei Yang Date: Tue, 2 Jun 2020 18:17:34 +0100 Subject: [PATCH] aarch64: Fix an ICE in aarch64_short_vector_p [PR95459] In aarch64_short_vector_p, we are simply checking whether a type (and a mode) is a 64/128-bit short vector or not. This should not be affected by the value of TARGET_SVE. Simply leave later code to report an error if SVE is disabled. 2020-06-02 Felix Yang gcc/ PR target/95459 * config/aarch64/aarch64.c (aarch64_short_vector_p): Leave later code to report an error if SVE is disabled. gcc/testsuite/ PR target/95459 * gcc.target/aarch64/mgeneral-regs_6.c: New test. --- gcc/config/aarch64/aarch64.c | 3 ++- .../gcc.target/aarch64/mgeneral-regs_6.c | 15 +++++++++++++++ 2 files changed, 17 insertions(+), 1 deletion(-) create mode 100644 gcc/testsuite/gcc.target/aarch64/mgeneral-regs_6.c diff --git a/gcc/config/aarch64/aarch64.c b/gcc/config/aarch64/aarch64.c index 7feff77adf6..6352d4ff78a 100644 --- a/gcc/config/aarch64/aarch64.c +++ b/gcc/config/aarch64/aarch64.c @@ -16800,7 +16800,8 @@ aarch64_short_vector_p (const_tree type, { /* Rely only on the type, not the mode, when processing SVE types. */ if (type && aarch64_some_values_include_pst_objects_p (type)) - gcc_assert (aarch64_sve_mode_p (mode)); + /* Leave later code to report an error if SVE is disabled. */ + gcc_assert (!TARGET_SVE || aarch64_sve_mode_p (mode)); else size = GET_MODE_SIZE (mode); } diff --git a/gcc/testsuite/gcc.target/aarch64/mgeneral-regs_6.c b/gcc/testsuite/gcc.target/aarch64/mgeneral-regs_6.c new file mode 100644 index 00000000000..427ae6a0e4b --- /dev/null +++ b/gcc/testsuite/gcc.target/aarch64/mgeneral-regs_6.c @@ -0,0 +1,15 @@ +/* { dg-options "-O2 -march=armv8.2-a+sve" } */ +/* { dg-prune-output "compilation terminated" } */ + +#include + +#pragma GCC push_options +#pragma GCC target "general-regs-only" + +svint8x2_t +foo (svint8_t x0, svint8_t x1) /* { dg-error {'foo' requires the SVE ISA extension} } */ +{ + return svcreate2 (x0, x1); /* { dg-error {ACLE function 'svcreate2_s8' is incompatible with the use of '-mgeneral-regs-only'} } */ +} + +#pragma GCC pop_options -- 2.30.2
