Created attachment 40484 [details] backtrace Using mesa from git commit 6a0255122a7d7c0aa09bceacda90a5cea67d5ee2 Yo Frankie! 1.1 (http://www.yofrankie.org/download/) causes an assertion failure: tgsi_ureg.h:790:ureg_writemask: Assertion `reg.File != TGSI_FILE_NULL' failed. I'm using r300g, but this seems to be a problem converting Mesa IR to TGSI. I've attached a backtrace.
