| | | | | | | | | | | | | This avoids extra if statements in the common case of just comparing two expressions that don't involve assignments or function calls, along with simplifying the handling of constant expressions. Reduces i965 instructions generated in unigine tropics and sanctuary, yofrankie, warsow, gstreamer shaders, and the weston compositor. shader-db results: Total instructions: 213052 -> 212752 38/1246 programs affected (3.0%) 14309 -> 14009 instructions in affected programs (2.1% reduction)

| | | | | | | | | | | | Before, we were only counting top-level instructions. But if we have an assignment of a giant expression tree (such as the ones eventually generated by glsl-fs-unroll), we were counting the same as an assignment of a variable deref. glsl-fs-unroll-explosion now fails in a reasonable amount of time on i965 because the unrolling didn't go ridiculously far.

* ralloc: Make rewrite_tail increase "start" by the new text's length.Kenneth Graunke2012-02-284-16/+18
| | | | | | | | | | | | | | | | | | Both callers of rewrite_tail immediately compute the new total string length by adding the (known) length of the existing string plus the length of the newly appended text. Unfortunately, callers generally won't know the length of the new text, as it's printf-formatted. Since ralloc already computes this length, it makes sense to add it in and save the caller the effort. This simplifies both existing callers, but more importantly, will allow for cheap-appending in the next commit. v2: The link_uniforms code needs both the old and new length. Apply the obvious fix (which sadly makes it less of a cleanup).

* glsl: Avoid excessive loop unrolling.Mathias Fröhlich2012-02-091-0/+15
| | | | | | | | | | | | | | | | | | | Avoid unrollong loops that are either nested loops or where the loop body times the unroll count is huge. The change is far from being perfect but it extends the loop unrolling decision heuristic by some additional safeguard. In particular this cuts down compilation of a shader precomputing atmospheric scattering integral tables containing two nesting levels in a loop from something way beyond some minutes (I never waited for it to finish) to some fractions of a second.

* glsl: Avoid ralloc_stealing a long-lived object to a short-lived parentCarl Worth2012-02-021-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 6ecee54a9aecc120cb68b02f7e14dcac86b9eca2 a call to talloc_reference was replaced with a call to talloc_steal. This was in preparation for moving to ralloc which doesn't support reference counting. The justification for talloc_steal within token_list_append in that commit is that the tokens are being copied already. But the copies are shallow, so this does not work. Fortunately, the lifetime of these tokens is easy to understand. A token list for "replacements" is created and stored in a hash table when a function-like macro is defined. This list will live until the macro is #undefed (if ever). Meanwhile, a shallow copy of the list is created when the macro is used and the list expanded. This copy is short-lived, so is unsuitable as a new parent. So we can just let the original, longer-lived owner continue to own the underlying objects and things will work.

* glcpp: Fix so that trailing punctuation does not prevent macro expansionCarl Worth2012-02-021-1/+9
| | | | | | | | | | | | | | | | | | | | The trick here is that flex always chooses the rule that matches the most text. So with a input text of "two:" which we want to be lexed as an IDENTIFIER token "two" followed by an OTHER token ":" the previous OTHER rule would match longer as a single token of "two:" which we don't want. We prevent this by forcing the OTHER pattern to never match any characters that appear in other constructs, (no letters, numbers, #, _, whitespace, nor any punctuation that appear in CPP operators).

| | | | | | | | | | | | | | | | | | | Exporting a publicly visible class with a generic name like "variable_entry" via ir_variable_refcount.h is kind of mean. Many IR transformers would like to define their own "variable_entry" class. If they accidentally include this header, the compiler/linker may get confused and try to instantiate the wrong variable_entry class, leading to bizarre runtime crashes. The hope is that renaming this one will allow .cpp files to safely declare and use their own file-scope "variable_entry" classes. This avoids crashes caused by converting src/glsl to automake.

| | | | | | | | | | | | | | | | | | | | | | | | | Previous to this patch, we didn't do the limit check for MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS until the end of the store_tfeedback_info() function, *after* storing all of the transform feedback info in the gl_transform_feedback_info::Outputs array. This meant that the limit check wouldn't prevent us from overflowing the array and corrupting memory. This patch moves the limit check to the top of tfeedback_decl::store() so that there is no risk of overflowing the array. It also adds assertions to verify that the checks for MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS and MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS are sufficient to avoid array overflow. Note: strictly speaking this patch isn't necessary, since the maximum possible number of varyings is MAX_VARYING (16), whereas the size of the Outputs array is MAX_PROGRAM_OUTPUTS (64), so it's impossible to have enough varyings to overflow the array. However it seems prudent to do the limit check before the array access in case these limits change in the future. Reviewed-by: Ian Romanick <[email protected]>
