Dear testers,
8.0.0-rc2 has been tagged from the release_80 branch at r353413.
Please run the test script, share your results, and upload binaries.
I'll get the source tarballs and docs published as soon as possible,
and binaries as they become available.
Thanks,
Hans

Hello,
We have started to build the 8.x branch and part of our build process is to run check-clang, check-llvm and check-lld on Linux, Windows, Macos and FreeBSD. Is there a test report or file we can collect in the CI and share with the community if there is interest?

Hi,

rc2 build on Ubuntu 16.04 saw a stage 2/3 mismatch on X86IselLowering.cpp.o -- I didn't try to build rc1 for 16.04 but I can try it now to see if it's there too.
I can pass along logs if anyone wants to investigate. On Thu, Feb 7, 2019 at 9:41 AM Hans Wennborg via Release-testers < [hidden email]> wrote: Dear testers,

rc1 did not exhibit this mismatch. A repeat of the rc2 build repeated the mismatch. I diff'd the disassembly between phase 2 and phase 3 and the difference is the same on both builds. The difference follows:
# diff x86isel_p{2,3}.s 2c2 < Phase2/Release/llvmCore-8.0.0-rc2.obj/lib/Target/X86/CMakeFiles/LLVMX86CodeGen.dir/X86ISelLowering.cpp.o: file format elf64-x86-64 --- > Phase3/Release/llvmCore-8.0.0-rc2.obj/lib/Target/X86/CMakeFiles/LLVMX86CodeGen.dir/X86ISelLowering.cpp.o: file format elf64-x86-64 121757c121757 < 863: 48 8b 84 24 e0 05 00 mov 0x5e0(%rsp),%rax --- > 863: 48 8b 84 24 b0 01 00 mov 0x1b0(%rsp),%rax 121759c121759 < 86b: 48 33 84 24 b0 01 00 xor 0x1b0(%rsp),%rax --- > 86b: 48 33 84 24 e0 05 00 xor 0x5e0(%rsp),%rax 121761,121762c121761,121762 < 873: 8b 8c 24 e8 05 00 00 mov 0x5e8(%rsp),%ecx < 87a: 33 8c 24 b8 01 00 00 xor 0x1b8(%rsp),%ecx --- > 873: 8b 8c 24 b8 01 00 00 mov 0x1b8(%rsp),%ecx > 87a: 33 8c 24 e8 05 00 00 xor 0x5e8(%rsp),%ecx

This is quite odd, because libc++ trunk has no mentions of `_Float16`, and I see none here:

Uploaded ARM & AArch64:

clang+llvm-8.0.0-rc2-aarch64-linux-gnu.tar.xz

clang+llvm-8.0.0-rc2-armv7a-linux-gnueabihf.tar.xz
Same as before, ARM looks fine but we have a MSan failure on AArch64
(I haven't yet managed to reproduce it outside Jenkins though, I'll
try harder).
Cheers,
Diana

Any tips or suggestions on how to isolate or identify this defect? It seems non-trivial to bisect this failure.
Hans: presumably this bug should block the 8.0 release? rc1 did not exhibit this mismatch. A repeat of the rc2 build repeated the mismatch. I diff'd the disassembly between phase 2 and phase 3 and the difference is the same on both builds. The difference follows:
# diff x86isel_p{2,3}.s 2c2 < Phase2/Release/llvmCore-8.0.0-rc2.obj/lib/Target/X86/CMakeFiles/LLVMX86CodeGen.dir/X86ISelLowering.cpp.o: file format elf64-x86-64 --- > Phase3/Release/llvmCore-8.0.0-rc2.obj/lib/Target/X86/CMakeFiles/LLVMX86CodeGen.dir/X86ISelLowering.cpp.o: file format elf64-x86-64 121757c121757 < 863: 48 8b 84 24 e0 05 00 mov 0x5e0(%rsp),%rax --- > 863: 48 8b 84 24 b0 01 00 mov 0x1b0(%rsp),%rax 121759c121759 < 86b: 48 33 84 24 b0 01 00 xor 0x1b0(%rsp),%rax --- > 86b: 48 33 84 24 e0 05 00 xor 0x5e0(%rsp),%rax 121761,121762c121761,121762 < 873: 8b 8c 24 e8 05 00 00 mov 0x5e8(%rsp),%ecx < 87a: 33 8c 24 b8 01 00 00 xor 0x1b8(%rsp),%ecx --- > 873: 8b 8c 24 b8 01 00 00 mov 0x1b8(%rsp),%ecx > 87a: 33 8c 24 e8 05 00 00 xor 0x5e8(%rsp),%ecx

Unfortunately I had to disable compiler-rt for this test run, as most of the sanitizers are totally broken. They get into an endless recursive loop between AsanTSDGet() and the __tls_get_addr() interceptor, and crash with DEADLYSIGNAL due to stack overflow. I haven't found the time to further diagnose this.
Main test results on amd64-freebsd11:
Expected Passes : 53882
Expected Failures : 220
Unsupported Tests : 1081
Unresolved Tests : 10
Unexpected Passes : 3
Unexpected Failures: 60
Main test results on i386-freebsd11:
Expected Passes : 53729
Expected Failures : 236
Unsupported Tests : 903
Unresolved Tests : 10
Unexpected Passes : 5
Unexpected Failures: 178
The unresolved tests are due to a number of tests hanging in <defunct> state, forcing me to kill their parent .py processes.
