2013-04-17i965: Fail to blit rather than assert on invalid pitch requirements.Kenneth Graunke1-2/+2
Dungeon Defenders hits TexImage()'s try_pbo_upload() path where image->Width == 2, which doesn't meet intelEmitCopyBlit's requirement that the pitch needs to be a multiple of 4. Since intelEmitCopyBlit can already fail for a myriad of other reasons, and it's not clear that other callers are immune to this failure mode, simply make it return false rather than assert.

2013-04-17glsl: Fix array indexing when constant folding built-in functions.Paul Berry1-1/+1
Mesa constant-folds built-in functions by using a miniature GLSL interpreter (see ir_function_signature::constant_expression_evaluate_expression_list()). This interpreter had a bug in its handling of array indexing, which caused expressions like "m[i][j]" (where m is a matrix) to be handled incorrectly. Specifically, it incorrectly treated j as indexing into the whole matrix (rather than indexing just into the vector m[i]); as a result the offset computed for m[i] was lost and m[i][j] was treated as m[j][0].

2013-04-17gallivm: fix return opcode handling in main function of a shaderRoland Scheidegger2-3/+18
If we're in some conditional or loop we must not return, or the code after the condition is never executed. (v2): And, we also can't just continue as nothing happened, since the mask update code would later check if we actually have a mask, so we need to remember that there was a return in main where we didn't exit (to illustrate this, a ret in a if clause would cause a mask update which is still ok as we're in a conditional, but after the endif the mask update code would drop the mask hence bringing execution back to pixels which should have their execution mask set to zero by the ret).

2013-04-17i965: Apply depthstencil alignment workaround when doing fast clears.Paul Berry1-1/+5
Fast depth clears have the same depth/stencil alignment requirements as other drawing operations. Therefore, we need to call brw_workaround_depthstencil_alignment() from both the clear and drawing paths. Without this fix, we get image corruption if the following conditions hold: (a) the first ever drawing operation to a depth miplevel (or the first drawing operation after having used the texture for sampling) is a clear, (b) the depth miplevel has a size that is eligible for fast depth clears, and (c) the depth miplevel has an offset within the miptree that isn't 8x8 aligned.

2013-04-17llvmpipe: tweak CMD_BLOCK_MAX and LP_SCENE_MAX_SIZEBrian Paul1-2/+8
We advertise a max texture/surfaces size of 8K x 8K but the old values for these limits didn't actually allow us to handle that surface size. For 8K x 8K we'll have 16384 bins. Each bin needs at least one cmd_block object which was 2192 bytes in size. Since 16384 * 2192 exceeded LP_SCENE_MAX_SIZE we'd silently fail in lp_scene_new_data_block() and not draw the complete scene. By reducing CMD_BLOCK_MAX to 29 we get nice 512-byte cmd_blocks. And by increasing LP_SCENE_MAX_SIZE to 9 MB we can allocate enough command blocks for 8K x 8K, plus a few regular data blocks. Fixes the (improved) piglit fbo-maxsize test.

2013-04-17st/mesa: fix polygon offset state translation logicBrian Paul1-7/+3
The old logic was kind of twisted, but seemed to work in practice. Note: This is a candidate for the stable branches. Reviewed-by: José Fonseca <jfonseca@vmware.com> (cherry picked from commit a2c105e31e47779ce1ddd80c62fc436292e40436)
2013-04-17draw: fix broken polygon offset stageBrian Paul1-3/+37
There were several issues. We weren't handling different front/back polygon fill modes. We weren't checking whether the offset applied to fill mode vs. line mode vs. point mode. Fixes problems found with the Visualization Toolkit (VTK) test suite. Note: This is a candidate for the stable branches.

2013-04-17llvmpipe: add missing checks for polygon offset point/line modesBrian Paul1-0/+6
The llvm pipeline handles regular filled triangle offsets, but it doesn't handle offsets for triangles drawn in point or line mode. Fixes failures found with new piglit polygon-mode-offset test. Note: This is a candidate for the stable branches. Reviewed-by: Jose Fonseca <jfonseca@vmware.com> (cherry picked from commit f93c5800637fd0967d53a4bc2b652d5f93d17d5d)
