my source code is add.cl,the code is
kernel void add(global int* a, global int *b) { int gid = get_global_id(0); b[gid] = a[gid] + a[gid]; }
I use command: clang -c -x cl -emit-llvm -S -cl-std=CL2.0 -Xclang -finclude-default-header add.cl -o add.bc
then use: llc -march=riscv32 -filetype=obj add.bc -o add.o
but it reports me some bugs,like
LLVM ERROR: RV64 target requires an RV64 CPU PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace. Stack dump: 0. Program arguments: llc -march=riscv64 -filetype=obj add.bc -o add.o
