[RISCV] Function calls from __attribute__((target("arch=+zvl512b"))) give fatal error #114117
Closed as not planned
Description
The code:
#include <riscv_vector.h>
int ext(int x);
__attribute__((target("arch=+zvl512b")))
int foo(int x) {
return ext(x);
}(https://godbolt.org/z/Tbhh7vnd6) compiled with -march=rv64gcv gives this error:
fatal error: error in backend: riscv-v-vector-bits-min specified is lower than the Zvl*b limitation
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
