[clang-cl] Due to #pragma function, no_builtin attribute is incorrectly added to functions #116256
Description
Consider the following example (due to the selected function name, this example is arm64 specific):
extern "C" __inline float __cdecl fabsf( float _X);
#pragma function(fabsf)
__inline float __cdecl fabsf( float _X)
{
return 0;
}
struct A {
int foo() = delete;
A() = default;
};
int main() {
return 0;
}
This gets successfully compiled with arm64 latest (14.41) MSVC.
However, with clang (with -fms-compatibility), the following errors occur:
error: no_builtin attribute has no effect on defaulted or deleted functions
error: no_builtin attribute has no effect on defaulted or deleted functions
2 errors generated.
Compiler returned: 1
