Would it be possible to improve error handling here? At least some tracing would be nice. From your analysis it looks like this might affect more platforms and not just armv7, and we wouldn't have noticed anything were it not for the backend bug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1993800 Title: LLVM ERROR: Cannot select: 0x2f689c8: v4i32 = ARMISD::VCMPZ 0x2f696b8, Constant:i32<2> Status in LLVM: New Status in llvm-toolchain-15 package in Ubuntu: Confirmed Status in mesa package in Ubuntu: Confirmed Status in llvm-toolchain-15 package in openSUSE: Unknown Bug description: LLVM ERROR: Cannot select: 0x2f689c8: v4i32 = ARMISD::VCMPZ 0x2f696b8, Constant:i32<2> 0x2f696b8: v4i32,ch = ARMISD::VLD1DUP<(load (s32) from %ir.212)> 0x2aad434, 0x2f84090:1, Constant:i32<4> 0x2f84090: i32,i32,ch = load<(load (s32) from %ir.209, align 8), <post-inc>> 0x2aad434, 0x2f63a30, Constant:i32<64> 0x2f63a30: i32,ch = CopyFromReg 0x2aad434, Register:i32 %23 0x2f51c10: i32 = Register %23 0x2f82500: i32 = Constant<64> 0x2f81b28: i32 = Constant<4> 0x2f81e40: i32 = Constant<2> In function: fs_variant_partial [https://launchpadlibrarian.net/629171689/buildlog_ubuntu-kinetic- armhf.mutter_43.0-1ubuntu3_BUILDING.txt.gz] Although "LLVM ERROR: Cannot select" seems to be from LLVM, I can't determine what project "fs_variant_partial" is in. Sounds like it might be in some old version of Mesa? The start of the log suggests it's running on focal.
