Hi Yin, MCA does support the –mcpu and –mtriple options. We have one arm test in llvm/test/tools/llvm-mca/ARM for a cortex-9, which is an Out of Order chip.

Hi Matt, Thanks you so much for the reply! I've tried the llvm-mca, it is helpful. I was wondering whether the llvm-mca support the assembly code for the ARM? I cross-compile the test file for ARM like that: clang test.c -O2 -target arm-linux-gnueabihf -static -S -o test.s If I want to check the performance using llvm-mca, is there any option of "-mcpu" for ARM ? Thanks, Yin
