It was flagging a last_bo update even when last_bo didn't change, but
another part was failing to update last_bo when it should have.
|
|
Failure to consistently do so resulted in mismatched aligned versus
unaligned alloc/free.

This patch is a variant of a submission by Michal Wajdeczko to fix
oglconform fpalu failures.

While OPCODE_SWZ has usually been optimized away in pass0, it may still
exist if a SWZ with dst saturate was emitted in pass_fp. Fixes an error
in oglconform fpalu.c.

The pass1 optimization stage clears out writemasks and registers, but the
instructions themselves are still being processed at this stage, and could

We always need to do PBO validation, so do that in core Mesa before calling driver routine.

Helper functions for (some) drivers, including swrast.

In _mesa_Bitmap, can't early return if bitmap ptr is NULL, it may be an offset
into a PBO. Similarly for _mesa_GetTexImage.

Fixes valgrind warnings, and potential performance loss from cache misses.
