* glsl linker: compare interface blocks during interstage linkingKenneth Graunke2013-05-231-0/+4
| | | | | | | | | | | | Verify that interface blocks match when linking separate shader stages into a program. Fixes piglit glsl-1.50 tests: * linker/interface-blocks-vs-fs-member-count-mismatch.shader_test * linker/interface-blocks-vs-fs-member-order-mismatch.shader_test Signed-off-by: Kenneth Graunke <[email protected]> Signed-off-by: Jordan Justen <[email protected]>
* glsl linker: compare interface blocks during intrastage linkingJordan Justen2013-05-231-0/+4
| | | | | | | | | | | | | | | | Verify that interface blocks match when combining compilation units at the same stage. (For example, when merging all vertex shaders.) Fixes piglit glsl-1.50 test: * linker/interface-blocks-multiple-vs-member-count-mismatch.shader_test v5 (Ken): Rename to link_interface_blocks.cpp and drop the separate .h file for consistency with other linker code. Remove "ok" variable. Fold cross_validate_interface_blocks into its caller. Signed-off-by: Jordan Justen <[email protected]> Signed-off-by: Kenneth Graunke <[email protected]>
* glsl: Rename uniform_field_visitor to program_resource_visitor.Paul Berry2013-02-041-16/+17
| | | | | | | | | | | | | | | | There's actually nothing uniform-specific in uniform_field_visitor. It is potentially useful for all kinds of program resources (in particular, future patches will use it for transform feedback varyings). This patch renames it to program_resource_visitor, and clarifies several comments, to reflect the fact that it is useful for more than just uniforms. NOTE: This is a candidate for the 9.1 branch.

* glsl: Add new uniform_field_visitor::process variantIan Romanick2013-01-251-0/+17
| | | | | | | | | | This flavor takes a type and a base name. It will be used to handle cases where the block name (instead of the instance name) is used for an interface block.

* linker: Refactor intra-stage block compatabililty testingIan Romanick2013-01-251-0/+4
| | | | | | | | | | | | | | | | Also slightly change the compatibility test. Instead of comparing the offsets of the block variables, compare the packing mode of the blocks. Ideally we don't want to assign the offsets until a later stage of linking. This is put in a new file called link_uniform_blocks.cpp. Some new functions related to uniform blocks are going to live in that file as well.

* 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).

| | | | | | | | | | | | 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.
