* glsl: Assign locations for uniforms in UBOs using the std140 rules.Eric Anholt2012-07-201-0/+3

* glsl: Merge the lists of uniform blocks into the linked shader program.Eric Anholt2012-07-201-0/+6

* glsl: Set initial values for uniforms in the linkerIan Romanick2012-05-231-0/+3
| | | | | | | | | | | | | | v2: Fix handling of arrays-of-structure. Thanks to Eric Anholt for pointing this out. v3: Minor comment change based on feedback from Ken. Fixes piglit glsl-1.20/execution/uniform-initializer/fs-structure-array and glsl-1.20/execution/uniform-initializer/vs-structure-array.

* ralloc: Make rewrite_tail increase "start" by the new text's length.Kenneth Graunke2012-02-281-1/+1
| | | | | | | | | | | | | | | | | | 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).

* linker: Make linker_{error,warning} generally availableIan Romanick2011-08-021-3/+0
| | | | | | | | | | linker_warning is a new function. It's identical to linker_error except that it doesn't set LinkStatus=false and it prepends "warning: " on messages instead of "error: ".

* linker: Make linker_error set LinkStatus to falseIan Romanick2011-08-021-1/+1
| | | | | | | | | | | | Remove the other places that set LinkStatus to false since they all immediately follow a call to linker_error. The function linker_error was previously known as linker_error_printf. The name was changed because it may seem surprising that a printf function will set an error flag.

* linker: First bits of intrastage, intershader function linkingIan Romanick2010-07-191-0/+35
This handles the easy case of linking a function in a different compilation unit that doesn't call any functions or reference any global variables.
