* mesa: fix prog_optimize.c assertions triggered by SWZ opcodeBrian Paul2014-09-181-5/+4
| | | | | | | | | | | | | The SWZ instruction can have swizzle terms >4 (SWIZZLE_ZERO, SWIZZLE_ONE). These swizzle terms caused a few assertions to fail. This started happening after the commit "mesa: Actually use the Mesa IR optimizer for ARB programs." when replaying some apitrace files. A new piglit test (tests/asmparsertest/shaders/ARBfp1.0/swz-08.txt) exercises this. Cc: "10.3" <[email protected]> Reviewed-by: Charmaine Lee <[email protected]>
* Eliminate several cases of multiplication in arguments to callocCarl Worth2014-09-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | In commit 32f2fd1c5d6088692551c80352b7d6fa35b0cd09, several calls to _mesa_calloc(x) were replaced with calls to calloc(1, x). This is strictly equivalent to what the code was doing previously. But for cases where "x" involves multiplication, now that we are explicitly using the two-argument calloc, we can do one step better and replace: calloc(1, A * B); with: calloc(A, B); The advantage of the latter is that calloc will detect any overflow that would have resulted from the multiplication and will fail the allocation, (whereas the former would return a small allocation). So this fix can change potentially exploitable buffer overruns into segmentation faults. Reviewed-by: Matt Turner <[email protected]>

* mesa: Add partial constant propagation pass for Mesa IRIan Romanick2011-08-161-0/+2
| | | | | | | | | | | | This cleans up some code generated by the IR-to-Mesa pass for i915. In particular, some shaders involving arrays of constant matrices result in really bad code. v2: Silence several warnings from merging the gl_constant_value work. Fix DP[23] folding. Add support for a bunch more opcodes that appear in piglit runs on i915. Reviewed-by: Eric Anholt <[email protected]>
