After D87528: Enable '#pragma STDC FENV_ACCESS' commit, our bots have a failure
on the wasm target, could you please take a look?
test.c:
double a, b;
c() {
#pragma STDC FENV_ACCESS ON
b == a;
}
Run `clang -cc1 -triple wasm32-unknown-wasi -emit-obj test.c` (clang needs to
be build with `-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly`)
Result:
clang:
/home/vm/src/llvm-project/llvm/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp:3764:
bool (anonymous namespace)::SelectionDAGLegalize::ExpandNode(llvm::SDNode *):
Assertion `!IsStrict && "Don't know how to expand for strict nodes."' failed.</pre>
