Hi LLVM developers, llc -march=mips -debug-only=isel was able to work in Nov 8 2017 https://reviews.llvm.org/D39723 But it doesn't work now: $ clang --version LLVM China clang version 6.0.0 (git at github.com:llvm-mirror/clang.git 9b7b03045ee9b5622028537266aafeb9ea218ac1) (git at github.com:llvm-mirror/llvm.git 3a26601a88394c02603b8756527c55df9ab94d78) (based on LLVM 6.0.0svn) Target:

Hi,It's first time to post question on community, so I'm not sure this is right way to ask. I'm hoping that someone can help me figure out how to speed up compilation. I'm working on LLVM 4.0 and modifying clang for my own purpose. It seems like after LLVM switches its compilation framework to cmake, the compile time is largely increased. It took almost over an hour even though I

Hi llvm-dev, I have unit tests set up in the XRay implementation (compiler-rt/lib/xray/tests/unit) following the pattern that the TSAN and other sanitiser unit tests. However, I'm running into the following problem: When I make changes to the runtime (in this case, XRay) and do `ninja all check-xray`, it seems that the unit tests don't get re-liked to the new version of the runtime. It

Dear llvm developpers, I followed the tutorial to build llvm and clang provided here: https://clang.llvm.org/get_started.html The sources are in sync with subversion repository, and I ended up with more than 30GB of binaries in llvm/bin as shown at the end of this message. I assume I did something wrong, but I did not find any entry in the doc that helps me understand how to reduce the size of
