[llvm-dev] llc: Unknown command line argument '-debug-only=isel'
-debug-only only works on builds with assertions enabled. Your version string says optimized build and doesn’t mention assertions.

[llvm-dev] llc: Unknown command line argument '-debug-only=isel'
I believe Crag answered your problem. As for the command line option, usually you can use `-help-hidden` to list developers' option, `-debug-only` is one example. 2017-12-21 23:39 GMT+08:00 Craig Topper via llvm-dev < llvm-dev at lists.llvm.org>:> -debug-only only works on builds with assertions enabled.

[llvm-dev] llc: Unknown command line argument '-debug-only=isel'
Thanks for your hint! I will try -DLLVM_ENABLE_ASSERTIONS=ON build option. 在 2017年12月21日 23:39, Craig Topper 写道:> -debug-only only works on builds with assertions enabled.
