As discussed in the PR, here is the testcase with the appropriate dg-* directives.
Tested on arm-none-eabi with 1 -mcpu=cortex-a7/-mfloat-abi=soft/-march=armv7ve+simd 2 -mcpu=cortex-a7/-mfloat-abi=hard/-march=armv7ve+simd 3 -mthumb/-mcpu=cortex-a7/-mfloat-abi=hard/-march=armv7ve+simd 4 -mthumb/-mfloat-abi=soft/-march=armv6s-m 5 -mthumb/-mfloat-abi=soft/-march=armv7-m 6 -mthumb/-mfloat-abi=hard/-march=armv7e-m+fp 7 -mthumb/-mfloat-abi=hard/-march=armv7e-m+fp.dp 8 -mthumb/-mfloat-abi=hard/-march=armv8-m.main+fp+dsp 9 -mthumb/-mfloat-abi=hard/-march=armv8.1-m.main+mve.fp+fp.dp 10 -mthumb/-mfloat-abi=hard/-march=armv8.1-m.main+mve The test is UNSUPPORTED with the first three ones (because of -mcpu=cortex-a7), ignored with armv6s-m, and PASSes with all the other ones, while it used crash without Jakub's fix (r12-8263), ie. FAIL with options 5,6,7,8,10. The test passed without Jakub's fix with option 9 because the problem happens only with an integer-only MVE. 2022-04-26 Christophe Lyon <christophe.l...@arm.com> gcc/testsuite/ PR tree-optimization/105374 * gcc.target/arm/simd/pr105374.C: New. --- gcc/testsuite/gcc.target/arm/simd/pr105374.C | 8 ++++++++ 1 file changed, 8 insertions(+) create mode 100644 gcc/testsuite/gcc.target/arm/simd/pr105374.C diff --git a/gcc/testsuite/gcc.target/arm/simd/pr105374.C b/gcc/testsuite/gcc.target/arm/simd/pr105374.C new file mode 100644 index 00000000000..2b9096f1f52 --- /dev/null +++ b/gcc/testsuite/gcc.target/arm/simd/pr105374.C @@ -0,0 +1,8 @@ +/* { dg-do compile } */ +/* { dg-options "-O3" } */ +/* { dg-require-effective-target arm_v8_1m_mve_ok } */ +/* { dg-add-options arm_v8_1m_mve } */ + +typedef float v4f __attribute__((vector_size(4 * sizeof(float)))); +v4f f_x, f_y; +long f() { return (f_x < f_y | f_x <= f_y)[2]; } -- 2.17.1
