ggml-cpu: cmake: append xsmtvdotii march for SpacemiT IME (#22317) * ggml-cpu: cmake: append xsmtvdotii march for SpacemiT IME When GGML_CPU_RISCV64_SPACEMIT=ON is set, ime1_kernels.cpp contains inline asm for the vmadot family which requires the xsmtvdotii custom extension.(problem can see in some blogs and make sure in K3 platform) The current CMakeLists does not include xsmtvdotii, so any toolchain that honours the explicit -march (tested with SpacemiT GCC 15.2) fails at the assembler stage: Error: unrecognized opcode `vmadot v16,v14,v0', extension `xsmtvdotii' required Append _xsmtvdotii to MARCH_STR when GGML_CPU_RISCV64_SPACEMIT is enabled so the IME path can actually build with a capable toolchain. No effect on builds that leave GGML_CPU_RISCV64_SPACEMIT off. toolchain from https://www.spacemit.com/community/resources-download/Tools * Update ggml/src/ggml-cpu/CMakeLists.txt Co-authored-by: alex-spacemit <jinghui.huang@spacemit.com> --------- Co-authored-by: alex-spacemit <jinghui.huang@spacemit.com>
