--- Comment #19 from iive at yahoo.com --- Created attachment 125130 --> https://bugs.freedesktop.org/attachment.cgi?id=125130&action=edit Octrodad crashing pixel shader - TGSI, disassembly, sbdump of IR code and crash backtrace I've discovered few more things. 1. When retracing with mesa3d debug enabled, the shader backend internal checker is run and it does detect errors (and crashes at failed assert). It seems to error out at shader 70 (a draw command before the one that hangs). I've attached a log that includes the output of `sbdump` too. 2. `R600_DEBUG=sbsafemath` could also be used to workaround the above crash and the original lockup. (Please test if this works with the other titles too.) Looking at the source, the 'safe math' option skips few optimization. The one that seems to cause problem is the call to `fold_assoc()` in `expr_handler::fold_alu_op2()` somewhere around `sb_expr.cpp:740`. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
