| | | | | | | | | | | | | | | | Patch provides new compiler option for backend to force unroll loops that have non-constant expression indexing on sampler arrays. This makes sure that we can never end up with a shader that uses loop induction variable as sampler array index but does not unroll because of having too much instructions.

| | | | | | | | | | | | | | | | | | | | Dynamic indexing of sampler arrays is prohibited by GLSL ES 3.00.

* util: port _mesa_strto[df] to CErik Faye-Lund2015-06-292-0/+6
| | | | | | | | | | | | | _mesa_strtod and _mesa_strtof are only used from the GLSL compiler and the ARB_[vertex|fragment]_program code, meaning that the locale doesn't need to be initialized before the first OpenGL context gets initialized. So let's use explicit initialization from the one-time init code instead of depending on a C++ compiler to initialize at image-load time.

| | | | | | | | | | | This reverts commit c2ff3485b3d48749ea9dcad07bc1a691627dc3e5. Ilia and I noticed a memory leak caused by this patch: at least with fixed-function programs, we clone things using ProgramResourceList as the context before reralloc makes it non-NULL. I believe Tapani found other bugs with these patches, so I'm just going to revert them for now and let him pursue them further.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are basically just moves, so they should be safe as well. When disabling i965's GLSL IR level scalarizer (channel expressions) pass, I started seeing NIR code like this: if ssa_21 { block block_1: /* preds: block_0 */ vec4 ssa_120 = vec4 ssa_82, ssa_83, ssa_84, ssa_30 /* succs: block_3 */ } else { block block_2: /* preds: block_0 */ /* succs: block_3 */ } block block_3: /* preds: block_1 block_2 */ vec4 ssa_33 = phi block_1: ssa_120, block_2: ssa_2 Previously, the GLSL IR scalarizer pass would break the vec4 into a series of fmovs, which were allowed by the peephole pass. But with the vec4 operation, they were not. We want to keep getting selects.

* glsl: Fail linkage when UBO exceeds GL_MAX_UNIFORM_BLOCK_SIZE.Jose Fonseca2015-06-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | It's not totally clear whether other Mesa drivers can safely cope with over-sized UBOs, but at least for llvmpipe receiving a UBO larger than its limit causes problems, as it won't fit into its internal display lists. This fixes piglit "arb_uniform_buffer_object-maxuniformblocksize fsexceed" without regressions for llvmpipe. NVIDIA driver also fails to link the shader from "arb_uniform_buffer_object-maxuniformblocksize fsexceed". Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=65525 PS: I don't recommend cherry-picking this for Mesa stable, as some app might inadvertently been relying on UBOs larger than GL_MAX_UNIFORM_BLOCK_SIZE to work on other drivers, so even if this commit is universally accepted it's probably best to let it mature in master for a while.

| | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, the following constructs (not an extensive list) would crash mesa: - mat2 foo = mat2(1); vec4 bar = vec4(foo); - mat3 foo = mat3(1); vec4 bar = vec4(foo); - mat3 foo = mat3(1); ivec4 bar = ivec4(foo); The first case is explicitely allowed by the GLSL spec, as seen on page 101 of the GLSL 4.40 spec: "vec4(mat2) // the vec4 is column 0 followed by column 1" The other cases are implicitely allowed also. The actual changes are quite minimal. We first split each column of the matrix to a list of vectors and then use them to initialize the vector. An additional check to make sure that we are not trying to copy 0 elements of a vector fix the (i)vec4(mat3) case as the last vector (3rd column) is not needed at all.

| | | | | | | | | | | | | | | This change introduces a new field in gl_uniform_storage to explicitely say that a uniform is built-in. In the case where it is, no storage is defined to make it clear that it is read-only from the mesa side. I fixed all the places in the code that made use of the structure that I changed. Any place making a wrong assumption and using the storage straight away will just crash.

| | | | | | | | | | | | | | | | | | lower_phis_to_scalar() pass recurses the instruction dependence graph to determine if all the sources of a given instruction are scalarizable. To prevent cycles, it temporary marks the phi instruction before recursing in, then updates the entry with the resulting value. However, it does not consider that the entry value may have changed after a recursion pass, hence causing a use-after-free situation and a crash. This patch fixes this by reloading the entry corresponding to the 'phi' after recursing and before updating its value.
