* st/mesa/r200/i915/i965: move ARB program fields into a unionTimothy Arceri2016-11-171-26/+27
| | | | | | | | | | | It's common for games to compile 2000 programs or more so at 32bits x 2000 programs x 22 fields x 2 (at least) stages This should give us something like 352 kilobytes in savings once we add some more glsl only fields. Reviewed-by: Emil Velikov <[email protected]>
* mesa: make use of ralloc when creating ARB asm gl_program fieldsTimothy Arceri2016-11-171-13/+15
| | | | | | | | | | | This will allow us to move the ARB asm fields in gl_program into a union as we will be able call ralloc_free() on the entire struct when destroying the context. In this change we switch over to using ralloc for the Instructions, String and LocalParams fields of gl_program. Reviewed-by: Emil Velikov <[email protected]>

* program: Shrink and rename SaturateMode field to Saturate.Matt Turner2015-06-031-2/+2
| | | | | | | | | | | It was 2 bits to accommodate SATURATE_PLUS_MINUS_ONE (removed by commit 09b566e1). A similar change was made to TGSI recently in commit e1c4e8aa. Reducing the size from 2 bits to 1 reduces the size of the bit fields from 17 bits to 16, which is a much nicer number. Reviewed-by: Brian Paul <[email protected]>

* 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]>
