Isolation tests:
- Commenting out CPUTYPE?=corei7-avx (all else the same) results in a successful build, / no assertion error.
- Removing -O2 (leaving CPUTYPE?=corei7-avx, and all else the same) results in a successful build / no assertion error.
- Using -O1 (leaving CPUTYPE?=corei7-avx, and all else the same) results in a successful build / no assertion error.
- Changing CPUTYPE?=corei7-avx -> sandybridge (all else the same), results in assertion error
Additional environment information:
- CPU: Intel Core i7-2600K
- FreeBSD is VirtualBox guest (dmest.boot attached)
Reproduced and reported upstream: https://bugs.llvm.org/show_bug.cgi?id=43916 A commit references this bug: Author: dim Date: Thu Nov 7 06:59:10 UTC 2019 New revision: 354429 URL: https://svnweb.freebsd.org/changeset/base/354429 Log: Merge commit 8e34dd941 from llvm git (by Sanjay Patel): [x86] avoid crashing when splitting AVX stores with non-simple type (PR43916) The store splitting transform was assuming a simple type (MVT), but that's not necessarily the case as shown in the test. This should fix 'Assertion failed: (isSimple() && "Expected a SimpleValueType!")' when building the security/openssl111 port targeting a CPU that supports AVX, but not AVX2, such as sandybridge. PR: 241747 MFC after: 1 month X-MFC-With: r353358 Changes: head/contrib/llvm/lib/Target/X86/X86ISelLowering.cpp Thank you Dimitry Any workarounds/changes that can be made to openssl111 in the meantime? (In reply to Kubilay Kocak from comment #5) Yes, just make sure the CPU type is not set, or set to something other than: sandybridge, core-avx-i or corei7-avx. Thanks Dimitry :) Will leave this in progress pending MFC If MFC is not required in stable/11 (due to it being a recent regression), just set the flag value to - This got fixed for stable/12 with the MFC of clang 9.0.1. |
