From: "slyfox at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/115115] [12/13/14/15 Regression] highway-1.0.7 wrong _mm_cvttps_epi32() constant fold Date: Wed, 15 May 2024 21:45:05 +0000 [thread overview] Message-ID: <bug-115115-4-hFjdQwajXZ@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-115115-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115115 --- Comment #1 from Sergei Trofimovich <slyfox at gcc dot gnu.org> --- If I understand the test correctly it uses 2^63 floating point value and converts it to uint32_t (or int32_t?). gcc's constant-fold saturates it to 2^63-1 while CPU keeps it at 2^63 (as if it was uint32_t). Original highway test names are: The following tests FAILED: 464 - HwyConvertTestGroup/HwyConvertTest.TestAllF2IPromoteTo/AVX2 # GetParam() = 512 (Subprocess aborted) 465 - HwyConvertTestGroup/HwyConvertTest.TestAllF2IPromoteTo/SSE4 # GetParam() = 2048 (Subprocess aborted) 466 - HwyConvertTestGroup/HwyConvertTest.TestAllF2IPromoteTo/SSSE3 # GetParam() = 4096 (Subprocess aborted) 467 - HwyConvertTestGroup/HwyConvertTest.TestAllF2IPromoteTo/SSE2 # GetParam() = 16384 (Subprocess aborted) 972 - HwyShuffle4TestGroup/HwyShuffle4Test.TestAllPer4LaneBlockShuffle/SSE2 # GetParam() = 16384 (Subprocess aborted)
