* glsl: Make ir_validate actually visit ir_if nodes.Kenneth Graunke2011-08-221-2/+3
| | | | | | | | | | | | There is no ir_hierarchical_visitor::visit(ir_if *) method, since ir_if is not a leaf node. Instead, there are visit_enter and visit_leave methods. Use visit_enter arbitrarily (either would work fine, though visit_enter will catch errors sooner). Found thanks to a warning emitted by Clang.

* glsl_to_tgsi: implement ir_binop_logic_or using an add w/saturate or add w/SLTBryan Cain2011-08-201-4/+27
| | | | | | | | | | | | | | | | | | | | | Logical-or is implemented using addition (followed by clamping to [0,1]) on values of 0.0 and 1.0. Replacing the logical-or operators with addition gives a + b which has a result on the range [0, 2]. Previously a SNE instruction was used to clamp the resulting logic value to [0,1]. In a fragment shader, using a saturate on the add has the same effect. Adding the saturate to the add is free, so (at least) one instruction is saved. In a vertex shader, using an SLT on the negation of the add result has the same effect. Many older shader architectures do not support the SNE instruction. It must be emulated using two SLT instructions and an ADD. On these architectures, the single SLT saves two instructions. Note that SNE is still used when integers are used for boolean values, since there is no such thing as an integer saturate, and older shader architectures without SNE don't support integers. This is a port of commit 41f8ffe5e07c to glsl_to_tgsi with integer support added.
* glsl_to_tgsi: implement ir_unop_logic_not using 1-xBryan Cain2011-08-201-1/+11
| | | | | | | Since our logic values are 0.0 (false) and 1.0 (true), 1.0 - x accurately implements logical not. This is a port of commit 6ad08989d7c1 to glsl_to_tgsi.

* st/egl: add android backendChia-I Wu2011-08-215-0/+781
| | | | | | | | | | Both HW and SW rendering are supported for Android. For SW rendering, we use the generic gralloc lock/unlock for mapping and unmapping color buffers (in winsys/android). For HW rendering, we need to know the real type of color buffers. This backend works with drm_gralloc, where a color buffer is backed by a GEM object.

| | | | | | | | | | | | | When ctx->Const.NativeIntegers is set, Core Mesa loads integer/boolean uniforms directly, rather than loading the floating point equivalent. So, when that's set, we don't need to perform any conversions. Unfortunately, we can't properly support native integers with the old vertex shader backend, so this patch leaves them disabled for now.

* mesa, glsl_to_tgsi: Add new gl_context::NativeIntegers flag.Kenneth Graunke2011-08-193-27/+37
| | | | | | | | | | | | | | | | | | | Previously, native integer support was based on whether the driver advertised GLSL 1.30 or not. However, drivers that natively support integers may wish to do so for older GLSL versions as well. Adding this new opt-in flag allows them to do so. Currently disabled by default on all drivers, which was the existing behavior (no drivers currently implement GLSL 1.30).
