* glsl/linker: Validate IR just before reparenting.Paul Berry2013-11-261-0/+5
| | | | | | | | | | | | | | | | | If reparent_ir() is called on invalid IR, then there's a danger that it will fail to reparent all of the necessary nodes. For example, if the IR contains an ir_dereference_variable which refers to an ir_variable that's not in the tree, that ir_variable won't get reparented, resulting in subtle use-after-free bugs once the non-reparented nodes are freed. (This is exactly what happened in the bug fixed by the previous commit). This patch makes this kind of bug far easier to track down, by transforming it from a use-after-free bug into an explicit IR validation error.

* glsl: Fix lowering of direct assignment in lower_clip_distance.Paul Berry2013-11-261-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 065da16 (glsl: Convert lower_clip_distance_visitor to be an ir_rvalue_visitor), we failed to notice that since lower_clip_distance_visitor overrides visit_leave(ir_assignment *), ir_rvalue_visitor::visit_leave(ir_assignment *) wasn't getting called. As a result, clip distance dereferences appearing directly on the right hand side of an assignment (not in a subexpression) weren't getting properly lowered. This caused an ir_dereference_variable node to be left in the IR that referred to the old gl_ClipDistance variable. However, since the lowering pass replaces gl_ClipDistance with gl_ClipDistanceMESA, this turned into a dangling pointer when the IR got reparented. Prior to the introduction of geometry shaders, this bug was unlikely to arise, because (a) reading from gl_ClipDistance[i] in the fragment shader was rare, and (b) when it happened, it was likely that it would either appear in a subexpression, or be hoisted into a subexpression by tree grafting. However, in a geometry shader, we're likely to see a statement like this, which would trigger the bug: gl_ClipDistance[i] = gl_in[j].gl_ClipDistance[i]; This patch causes lower_clip_distance_visitor::visit_leave(ir_assignment *) to call the base class visitor, so that the right hand side of the assignment is properly lowered.

| | | | | | | | | | | | | The previous commit fixes a bug wherein we would incorrectly refer to stale geometry shader prog_data when no geometry shader was active. This patch reduces the likelihood of that sort of bug occurring in the future by setting prog_data to NULL whenever there is no GS program.

* i965/gs: Properly skip GS binding table upload when no GS active.Paul Berry2013-11-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, in brw_gs_upload_binding_table(), we checked whether brw->gs.prog_data was NULL in order to determine whether a geometry shader was active. This didn't work: brw->gs.prog_data starts off as NULL, but it is set to non-NULL when a geometry shader program is built, and then never set to NULL again. As a result, if we called brw_gs_upload_binding_table() while there was no geometry shader active, but a geometry shader had previously been active, it would refer to a stale (and possibly freed) prog_data structure. This patch fixes the problem by modifying brw_gs_upload_binding_table() to use the proper technique to determine whether a geometry shader is active: by checking whether brw->geometry_program is NULL. This fixes the crash reported in comment 2 of bug 71870 (the incorrect rendering remains, however).

| | | | | | | | | | | | | | | | | | | The fast tiled texture upload code does not compile with GCC 4.8's -Og optimization flag. memcpy() has the always_inline attribute set. This poses a problem, since {x,y}tile_copy_faster calls it indirectly via {x,y}tile_copy, and {x,y}tile_copy normally aren't inlined at -Og. Using __attribute__((flatten)) tells GCC to inline every function call inside the function, which I believe was the author's intent. Fix suggested by Alexander Monakov.

| | | | | | | | | | | | | | | | | | | | I recently made us try two different things that tried to reduce register pressure so that we would be more likely to allocate successfully. But now that we have the logic for trying two, we can make the first thing we try be the normal, not-prioritizing-register-pressure heuristic. This means one less scheduling pass in the common case of that heuristic not producing spills, plus the best schedule we know how to produce, if that one happens to succeed. This is important, because our register allocation produces a lot of possibly avoidable dependencies for the post-register-allocation schedule, despite ra_set_allocate_round_robin().

| | | | | | | | | | | | | | | | | | | | | | | Commit 2f89662 added the driconf option 'clamp_max_samples'. In that commit, the option did not alter the context version. The neglect to alter the context version is a fatal issue for some apps. For example, consider running Chromium with clamp_max_samples=0. Pre-patch, Mesa creates a GL 3.0 context but clamps GL_MAX_SAMPLES to 0. This violates the GL 3.0 spec, which requires GL_MAX_SAMPLES >= 4. The spec violation causes WebGL context creation to fail in many scenarios because Chromium correctly assumes that a GL 3.0 context supports at least 4 samples. Since the driconf option was introduced largely for Chromium, the issue really needs fixing. This patch fixes calculation of the context version to respect the post-clamped value of GL_MAX_SAMPLES. This in turn fixes WebGL on Chromium when clamp_max_samples=0. Reviewed-by: Kenneth Graunke <[email protected]> Signed-off-by: Chad Versace <[email protected]>
