From: Christophe Lyon <clyon@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r12-8279] testsuite: Add arm testcase for PR105374 Date: Wed, 27 Apr 2022 08:20:03 +0000 (GMT) [thread overview] Message-ID: <20220427082003.1792E3858C53@sourceware.org> (raw) https://gcc.gnu.org/g:6c211e70eb9d89db2be630c0d5555d21e4aee144 commit r12-8279-g6c211e70eb9d89db2be630c0d5555d21e4aee144 Author: Christophe Lyon <christophe.lyon@arm.com> Date: Tue Apr 26 15:57:02 2022 +0100 testsuite: Add arm testcase for PR105374 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.lyon@arm.com> gcc/testsuite/ PR tree-optimization/105374 * gcc.target/arm/simd/pr105374.C: New.
