@ilovepi I minimised the failing issue from:
https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/src/graphics/lib/compute/spinel/ext/transform_stack/transform_stack.c
to:
```cpp
#include <math.h>
#include <stdio.h>
#define SPN_TRANSFORM_STACK_TAN(x_) tanf(x_)
float
spinel_transform_stack_push_skew_x(float theta)
{
float const tan_theta = SPN_TRANSFORM_STACK_TAN(theta);
return tan_theta;
}
int main() {
printf("%f\n", spinel_transform_stack_push_skew_x(1.05f));
return 0;
}
```
run like so:
```bash
farzon@devbox: projects/llvm-project$ <build_dir>/bin/clang <test_path>/test.c
-lm -o <test_out_path>/test.out
farzon@devbox: projects/llvm-project$ ./<test_out_path>/test.out
1.743315
```
The intrinsic should be able to be lowered now.
