Assertion `llvm::isUIntN(BitWidth, val) && "Value is not an N-bit unsigned value"' failed. #160981
Description
The assertion is hit when trying the following IR:
https://godbolt.org/z/6cbhrrbME
declare { float, i32 } @llvm.frexp.f32.i32(float)
define { float, i32 } @frexp_pos_denorm() {
%ret = call { float, i32 } @llvm.frexp.f32.i32(float bitcast (i32 8388607 to float))
ret { float, i32 } %ret
}Backtrace:
llc: /root/llvm-project/llvm/include/llvm/ADT/APInt.h:127: llvm::APInt::APInt(unsigned int, uint64_t, bool, bool): Assertion `llvm::isUIntN(BitWidth, val) && "Value is not an N-bit unsigned value"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
