simeng runs the FP32 SME instruction with an exception

[zhukang16]

I use your FP32 code to compile: armclang-static-march =armv8.4-a+ sve-Wall-O3 --target=aarch64-arm-none- eabi-o simeng_matmul_fp32 main.c matmu. c Then I ran Simeng:/SimEng/bin/simeng /SimEng/configs/a64fx_SME.yaml /SimEng/simeng_matmul_fp32 However, the following error will be reported: [SimEng] Build metadata: [SimEng] Version: 0.9.6 [SimEng] Compile Time - Date: 10:28:12 - Jan 2 2025 [SimEng] Build type: Release [SimEng] Compile options: $<$<COMPILE_LANGUAGE:CXX>:-fno-rtti>;-Wall;-pedantic;-Werror [SimEng] Test suite: ON

Hi, please could you try running this on our dev branch?

I suspect that the compiler you are using has generated an instruction we do not have execution logic for yet on main, whereas dev is more up to date, especially for SME related things
