* glsl: rewrite glsl_type::record_key_hash() to avoid buffer overflowBrian Paul2015-04-221-10/+13
| | | | | | | | | | | | | | | | | | | | This should be more efficient than the previous snprintf() solution. But more importantly, it avoids a buffer overflow bug that could result in crashes or unpredictable results when processing very large interface blocks. For the app in question, key->length = 103 for some interfaces. The check if size >= sizeof(hash_key) was insufficient to prevent overflows of the hash_key[128] array because it didn't account for the terminating zero. In this case, this caused the call to hash_table_string_hash() to return different results for identical inputs, and then shader linking failed. This new solution also takes all structure fields into account instead of just the first 15 when sizeof(pointer)==8.

* glsl: Mark array access when copying to a temporary for the ?: operator.Kenneth Graunke2015-03-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Piglit's spec/glsl-1.20/compiler/structure-and-array-operations/ array-selection.vert test contains the following code: gl_Position = (pick_from_a_or_b ? a : b)[i]; where "a" and "b" are uniform vec4[2] variables. ast_to_hir creates a temporary vec4[2] variable, conditional_tmp, and generates an if-block to copy one or the other: (declare (temporary) (array vec4 2) conditional_tmp) (if (var_ref pick_from_a_or_b) ((assign () (var_ref conditional_tmp) (var_ref a))) ((assign () (var_ref conditional_tmp) (var_ref b)))) However, we failed to update max_array_access for "a" and "b", so it remained 0 - here, the whole array is being accessed. At link time, update_array_sizes() used this bogus information to change the types of "a" and "b" to vec4[1]. We then had assignments from a vec4[1] to a vec4[2], which is highly illegal. This tripped assertions in nir_split_var_copies with scalar VS.

* glsl: Reduce memory consumption of copy propagation passes.Kenneth Graunke2015-02-242-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | opt_copy_propagation and opt_copy_propagation_elements create new ACP and Kill sets each time they enter a new control flow block. For if blocks, they also copy the entire existing ACP set contents into the new set. When we exit the control flow block, we discard the new sets. However, we weren't freeing them - so they lived on until the pass finished. This can waste a lot of memory (57MB on one pessimal shader). This patch makes the pass allocate ACP entries using this->acp as the memory context, and Kill entries out of this->kill. It also steals kill entries when moving them from the inner kill list to the parent. It then frees the lists, including their contents. v2: Move ralloc_free(this->acp) just before this->acp = orig_acp (suggested by Eric Anholt).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, Mesa uses the lowering pass MOD_TO_FRACT to implement mod(x,y) as y * fract(x/y). This implementation has a down side though: it introduces precision errors due to the fract() operation. Even worse, since the result of fract() is multiplied by y, the larger y gets the larger the precision error we produce, so for large enough numbers the precision loss is significant. Some examples on i965: Operation Precision error ----------------------------------------------------- mod(-1.951171875, 1.9980468750) 0.0000000447 mod(121.57, 13.29) 0.0000023842 mod(3769.12, 321.99) 0.0000762939 mod(3769.12, 1321.99) 0.0001220703 mod(-987654.125, 123456.984375) 0.0160663128 mod( 987654.125, 123456.984375) 0.0312500000 This patch replaces the current lowering pass with a different one (MOD_TO_FLOOR) that follows the recommended implementation in the GLSL man pages: mod(x,y) = x - y * floor(x/y) This implementation eliminates the precision errors at the expense of an additional add instruction on some systems. On systems that can do negate with multiply-add in a single operation this new implementation would come at no additional cost. v2 (Ian Romanick) - Do not clone operands because when they are expressions we would be duplicating them and that can lead to suboptimal code.

This worked pretty well, but for development the error messages were never very useful, Python tools couldn't understand the opcode list, and it was difficult to use nir_opcodes.h to do other things like autogenerate a builder API. Now, we store opcode information in nir_opcodes.py, and we have nir_opcodes_c.py to generate the old nir_opcodes.c and nir_opcodes_h.py to generate nir_opcodes.h, which contains all the enum names and gets included into nir.h like before. In addition to solving the above problems, using Python and Mako to generate everything means that it's much easier to add keep information centralized as we add new things like constant propagation that require per-opcode information. v2: - make Opcode derive from object (Dylan) - don't use assert like it's a function (Dylan) - style fixes for fnoise, use xrange (Dylan) - use iterkeys() in nir_opcodes_h.py (Dylan) - use pydoc-style comments (Jason) - don't make fmin/fmax commutative and associative yet (Jason) Signed-off-by: Connor Abbott <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> v3 Jason Ekstrand <[email protected]> - Alphabetize source file lists - Generate nir_opcodes.h in the builddir instead of the source dir - Include $(builddir)/src/glsl/nir in the i965 build - Rework nir_opcodes.h generation so it generates a complete header file instead of one that has to be embedded inside an enum declaration
