<pre>After upstream commit r355981, one of our internal tests started hitting an
error during compilation with optimizations enabled:
/* 1.cpp */
int test(int stuff)
{
int res = 0;
switch(__builtin_expect(stuff, stuff)) {
case 0:
res = 1;
break;
default:
break;
}
return res;
}
$ clang -c -O2 1.cpp
immarg operand has non-immediate parameter
%conv1 = sext i32 %2 to i64
%expval = call i64 @llvm.expect.i64(i64 %conv, i64 %conv1)
in function _Z4testi
fatal error: error in backend: Broken function found, compilation aborted!
clang-9: error: clang frontend command failed with exit code 70 (use -v to see
invocation)
clang version 9.0.0 (trunk 355981)
Target: x86_64-unknown-linux-gnu
Thread model: posix
