[llvm-dev] How to precisely reproduce the buildbot fail in local?

[Wang, Phoebe via llvm-dev]

Hi Yuanfang,

Great point!!
I still haven't gotten the assertion, but with thoroughly debug, I believe it is the root cause. Thanks for your help!

Thanks
Phoebe

Sorry, I spoke too soon. Is "isMem()" needed in `isMemPlaceholder`?

Thanks Yuanfang.
Assertion was enabled with "-DLLVM_ENABLE_ASSERTIONS=True"
I also tried with debug type with no luck :(

Thanks
Phoebe

Enable assertion to see it?

Hi,

I have a patch that caused several buildbot fails in a lit test. The test passed with my local setup. Surprisingly, it passed even I used the same commands with the bot.


Here is one of the failed bot: https://urldefense.com/v3/__https://lab.llvm.org/buildbot*builders/110/builds/8880__;Iw!!JmoZiZGBv3RvKRSx!umeOkYKONJu8vyE4GXdjm3zdjzRr9nRGily-_lzpJ5LYDOeoEXd_Y-sdAwV-ISbFdA$ <https://urldefense.com/v3/__https://lab.llvm.org/buildbot*builders/110/builds/8880__;Iw!!JmoZiZGBv3RvKRSx!r6IHXSkbE6DnacmQoXRLiZs50WtTV2s18KqwxUpesCTMKnHmSiDJ2ohDfHpzs5Uj0g$>
Here are steps I tried (used the identical command copy + paste from the bot):
$ cmake -G Ninja ../llvm/llvm -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=True '-DLLVM_LIT_ARGS='"'"'-v'"'"'' -DCMAKE_INSTALL_PREFIX=../stage1.install -DLLVM_ENABLE_ASSERTIONS=ON '-DCMAKE_C_FLAGS='"'"'-march=broadwell'"'"'' '-DCMAKE_CXX_FLAGS='"'"'-march=broadwell'"'"'' '-DLLVM_TARGETS_TO_BUILD='"'"'X86'"'"'' '-DLLVM_ENABLE_PROJECTS=llvm;clang'
$ ninja check-all

Any idea how can I reproduce it locally?

Thanks
Phoebe
