* Revert "glsl: Skip processing the first function's body in do_dead_functions()."Paul Berry2011-08-081-10/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | opt_dead_functions contained a shortcut to skip processing the first function's body, based on the assumption that IR functions are topologically sorted, with callees always coming before their callers (therefore the first function cannot contain any calls). This assumption turns out not to be true in general. For example, the following code snippet gets translated to IR that violates this assumption: void f(); void g(); void f() { g(); } void g() { ... } In practice, the shortcut didn't cause bugs because of a coincidence of the circumstances in which opt_dead_functions is called: (a) we do inlining right before dead function elimination, and inlining (when successful) eliminates all calls. (b) for user-defined functions, inlining is always successful, because previous optimization passes (during compilation) have reduced them to a form that is eligible for inlining. (c) the function that appears first in the IR can't possibly call a built-in function, because built-in functions are always emitted before the function that calls them. It seems unnecessarily fragile to have opt_dead_functions depend on these coincidences. And the next patch in this series will break (c). So I'm reverting the shortcut. The consequence will be a slight increase in link time for complex shaders. This reverts commit c75427f4c8767e131e5fb3de44fbc9d904cb992d. Reviewed-by: Kenneth Graunke <[email protected]>

* mesa: In validate_program(), initialize errMsg for safety.Kenneth Graunke2011-08-051-1/+1
| | | | | | | | | | | | | | | validate_program relies on validate_shader_program to fill in errMsg; empirically, there exist cases where that doesn't happen. While tracking those down may be worthwhile, initializing the string so we don't try to ralloc_strdup random garbage also seems wise. Fixes issues caught by valgrind while running some test case.

| | | | | | | | | | | | DRI2 will throw BadRequest for this when the client is not local, but DRI2 is an implementation detail and not something callers should have to know about. Silently swallow errors in this case, and just propagate the failure through DRI2Connect's return code. Note: This is a candidate for the stable release branches.

| | | | | | | | | This saves both register space and upload bandwidth for unused values. Note that previously we were relying on the visitor not initially generating references to different sets of uniforms between the 8-wide and 16-wide code generation, and now we're relying on them dead-code eliminating the same stuff, too.

| | | | | | | | | | | | | | | | Before, if any uniform or constant array was accessed with indirect addressing, st_translate_program() would emit uniform constants in the place of immediates. This behavior was unavoidable with ir_to_mesa/mesa_to_tgsi, but glsl_to_tgsi can work around it since the GLSL IR backend and the TGSI emission are both inside the state tracker.
