* st/mesa: handle new GLSL IR enumerants in switch statementsBrian Paul2013-01-251-2/+16

* st/mesa: do proper error checking for u_upload_alloc() callsBrian Paul2013-01-255-17/+26
| | | | | | | | | We weren't properly checking the return value of these calls (and calls to u_upload_data()) to detect OOM errors. Note: This is a candidate for the 9.0 branch. Reviewed-by: Jose Fonseca <[email protected]>

* glsl: Replace most default cases in switches on GLSL typeIan Romanick2013-01-251-3/+5
| | | | | | | | | | | | | | | This makes it easier to find switch-statements that need to be updated after a new GLSL_TYPE_* is added because the compiler will generate a warning. Switch-statements that only had a small number of cases (e.g., everything in ir_constant_expression.cpp) were not modified. I may regret that decision when we eventually add support for doubles.

* glsl: Eliminate ambiguity between function ins/outs and shader ins/outsPaul Berry2013-01-241-10/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the three ir_variable_mode enums: - ir_var_in - ir_var_out - ir_var_inout with the following five: - ir_var_shader_in - ir_var_shader_out - ir_var_function_in - ir_var_function_out - ir_var_function_inout This eliminates a frustrating ambiguity: it used to be impossible to tell whether an ir_var_{in,out} variable was a shader in/out or a function in/out without seeing where the variable was declared in the IR. This complicated some optimization and lowering passes, and would have become a problem for implementing varying structs. In the lisp-style serialization of GLSL IR to strings performed by ir_print_visitor.cpp and ir_reader.cpp, I've retained the names "in", "out", and "inout" for function parameters, to avoid introducing code churn to the src/glsl/builtins/ir/ directory. Note: a couple of comments in the code seemed to indicate that we were planning for a possible future in which geometry shaders could have shader-scope inout variables. Our GLSL grammar rejects shader-scope inout variables, and I've been unable to find any evidence in the GLSL standards documents (or extensions) that this will ever be allowed, so I've eliminated these comments.

* st/mesa: a couple fixes for st_BlitFramebuffer()Brian Paul2013-01-161-30/+52
| | | | | | | | | | | | 1. Loop over multiple destination color buffers. If we set glDrawBuffers(GL_FRONT_AND_BACK) we need to loop over multiple color buffers, blitting to each. 2. Add checks for null src/dst surface pointers. This fixes a crash in the piglit fbo-missing-attachment-blit test.

* st/mesa: try to find the format matching format+type in decompressed_with_blitMarek Olšák2013-01-041-19/+50
| | | | | | | | | | | | | | | There was the fast path based on _mesa_format_matches_format_and_type for GetTexImage, but it never worked, because the Mesa format we were testing there was always compressed. Further testing showed that the fast path had been completely broken. In this commit, the somewhat limited helper util_create_rgba_texture is no longer used and instead, custom code for the texture creation is added, which tries to find the best matching RGBA8 format, so that we can hit the fast path *always* if the read format is a variant of RGBA8 and supported by the driver.

| | | | | | | | | | | | | | | | | | ARB/EXT_timer_query's definition of GL_TIME_ELAPSED match precisely the subtraction of two GL_TIMESTAMP queries. And for a lot of drivers, that's precisely how they have to implement internally -- by emitting two hardware timestamp queries. So, to simplify driver implementation, simply allow doing so in the state tracker. Eventually if no driver implements PIPE_QUERY_TIME_ELAPSED then we could retire it.
