| | | | | | | | | | | | | This patch add correct vector addition and substraction intrisics when using Altivec with PPC. Current code uses default path and LLVM backend ends up issuing carry-out arithmetic instruction while it is expected saturated ones. It also includes a fix for PowerPC where char are unsigned by default, resulting in bogus values for vector shifting.

* i965/vs: Move struct brw_compile (p) entirely inside vec4_generator.Kenneth Graunke2012-11-283-4/+3
| | | | | | | | | | | | | | The brw_compile structure contains the brw_instruction store and the brw_eu_emit.c state tracking fields. These are only useful for the final assembly generation pass; the earlier compilation stages doesn't need them. This also means that the code generator for future hardware won't have access to the brw_compile structure, which is extremely desirable because it prevents accidental generation of Gen4-7 code.

* i965/vs: Split final assembly code generation out of vec4_visitor.Kenneth Graunke2012-11-284-53/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compiling shaders requires several main steps: 1. Generating VS IR from either GLSL IR or Mesa IR 2. Optimizing the IR 3. Register allocation 4. Generating assembly code This patch splits out step 4 into a separate class named "vec4_generator." There are several reasons for doing so: 1. Future hardware has a different instruction encoding. Splitting this out will allow us to replace vec4_generator (which relies heavily on the brw_eu_emit.c code and struct brw_instruction) with a new code generator that writes the new format. 2. It reduces the size of the vec4_visitor monolith. (Arguably, a lot more should be split out, but that's left for "future work.") 3. Separate namespaces allow us to make helper functions for generating instructions in both classes: ADD() can exist in vec4_visitor and create IR, while ADD() in vec4_generator() can create brw_instructions.

* i965/vs: Abort on unsupported opcodes rather than failing.Kenneth Graunke2012-11-281-3/+4
| | | | | | | | | | Final code generation should never fail. This is a bug, and there should be no user-triggerable cases where this could occur. Also, we're not going to have a fail() method after the split. Reviewed-by: Eric Anholt <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>
* i965/vs: Move uses of brw_compile from do_vs_prog to brw_vs_emit.Kenneth Graunke2012-11-283-14/+19
| | | | | | | | | | | | The brw_compile structure is closely tied to the Gen4-7 hardware encoding. However, do_vs_prog is very generic: it just calls out to get a compiled program and then uploads it. This isn't ultimately where we want it, but it's a step in the right direction: it's now closer to the code generator.

* i965/vs: Rework memory contexts for shader compilation data.Kenneth Graunke2012-11-285-8/+12
| | | | | | | | | | | | | | During compilation, we allocate a bunch of things: the IR needs to last at least until code generation...and then the program store needs to last until after we upload the program. For simplicity's sake, just keep it all around until we upload the program. After that, it can all be freed. This will also save a lot of headaches during the upcoming refactoring.

| | | | | | | | | | | This leaves only the final code generation stage in brw_vec4_emit.cpp, moving the payload setup, run(), and brw_vs_emit functions to brw_vec4.cpp. The fragment shader backend puts these functions in brw_fs.cpp, so this patch also helps with consistency.

* meta: Don't try to glOrtho when the draw buffer isn't initialized.Kenneth Graunke2012-11-281-3/+5
| | | | | | | | | | | | | | | I ran across this while running a glGenerateMipmap() test. _meta_GenerateMipmap sets MESA_META_TRANSFORM, which causes _mesa_meta_begin to try and set a default orthographic projection. Unfortunately, if the drawbuffer isn't set up, ctx->DrawBuffer->Width and Height are 0, which just causes an GL_INVALID_VALUE error.
