stderr with RADEON_DEBUG=fp
With shader detail=high the strogg radar becomes completely black. I think this corresponds to the two compiler errors (log attached).
I forgot to mention that this used to work couple of months ago.
Can you bisect?

I think this issue is duplicate of #36939, despite looking entirely different, bisect found the same commit.

Can you apply this patch and post the output of RADEON_DEBUG=fp again?

I applied the reverse of commit 217cd216eac65983004ca77a9e49dbfad1b720b6 to the compiler, and recorded stderr again with correct rendering.
And this time I didn't forget to compress it before uploading.

Can you try this patch? If it doesn't work, can you post the output again?
The patch fixed this one and #36939. Thanks.
Fixed in git commit 2d1004d9aa719bb93a4f057b0eefe88f23b44e44
