Summary: in etqw the strogg radar is black Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: aaalmosss@gmail.com

Created an attachment (id=50186) --> (https://bugs.freedesktop.org/attachment.cgi?id=50186) 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).

Can you bisect?

217cd216eac65983004ca77a9e49dbfad1b720b6 is the first bad commit commit 217cd216eac65983004ca77a9e49dbfad1b720b6 Author: Tom Stellard tstellar@gmail.com Date: Tue May 17 18:51:20 2011 -0700

r300/compiler: Fix bug in rc_get_variables()

Variables that write to the same source select need to pe paired together otherwise the register allocator might fail.

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

Verbose patch

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.
