* gallivm: implement seamless cube filteringRoland Scheidegger2013-10-213-40/+368
| | | | | | | | | | | | | | | | | | | | | | | | | For seamless cube filtering it is necessary to determine new faces and new coords per sample. The logic for this is _seriously_ complex (what needs to happen is very "asymmetric" wrt face, x/y under/overflow), further complicated by the fact that if the 4 samples are in a corner (meaning we only have actually 3 samples, and all 3 are on different faces) then falling off the edge is happening _both_ on x and y axis simultaneously. There was a noticeable performance hit in mesa's cubemap demo when seamless filtering was forced on (just below 10 percent or so in a debug build, when disabling all filtering hacks, otherwise it would probably be a bit more) and when always doing the logic, hence use a branch which it only does it if any of the pixels in a quad (or in two quads) actually hit this. With that there was no measurable performance hit in the cubemap demo (neither in a debug nor release buidl), but this will vary (cubemap demo very rarely hits edges). Might also be different on other cpus, as this forces SoA sampling path which potentially can be quite a bit slower. Note that as for corners, this code gets all the 3 samples which actually exist right, and the 4th texel will simply be the same as one of the others, meaning that filter weights will be a bit wrong. This however should be enough for full OpenGL (but not d3d10) compliance. Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* translate_sse: Fix generated code argument handling for msabi on x86_64Jon TURNEY2013-10-181-3/+11
| | | | | | | | | | | | | | | | translate_sse.c contains code for msabi on x86_64, but it appears to be untested. Currently arguments 1 and 2 passed to the generated code are moved as 32-bit quantities into the registers used by sysvabi, irrespective of the architecture. Since these may be pointers, they must be moved as 64-bit quantities to avoid truncation. Commit f4dd0991719ef3e2606920c5100b372181c60899 disabled tranlate_sse.c on MinGW x86_64, I don't know if was due to this issue, or a different one...

| | | | | | | | | | This reverts commit 94d05bf87a21bd364e84f699a0064e5fba58a6f9 as it has a few problems: - it breaks windows builds becuase env[LLVM_CXXFLAGS] is never set there - it is merging not only rtti, but the whole cxxflags (defines etc) which has proven to be a source of troubles (breaks debugging etc.)
* cso: fix incorrect sampler view count in cso_restore_sampler_views()Brian Paul2013-10-161-3/+6
| | | | | | | | | | | | | | | | | | During the recent bind_sampler_states() interface change in gallium we changed the CSO single_sampler_done() function so that if we were decreasing the number of sampler states bound in the driver, we'd null-out the "extra/old" sampler states to unbind them. See commit 1e2fbf265. However, we didn't make the corresponding fix for sampler views. This caused an assertion to fail in the svga driver which checked that the number of sampler views matched the number of sampler states. This patch fixes cso_restore_sampler_views() so that it nulls-out the extra/old sampler views if the number of new views is less than the number of current/old views.

* build: remove forced -fno-rttiAlexander von Gluck IV2013-10-141-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | * As discussed on the mailing list, forced no-rtti breaks C++ public API's such as the Haiku C++ libGL.so * -fno-rtti *can* be still set however instead of blindly forcing -fno-rtti, we can rely on the llvm-config --cppflags output. If the system llvm is built without rtti (default), the no-rtti flag will be present in llvm-config --cppflags (which we pick up on) If llvm is built with rtti (REQUIRES_RTTI=1), then -fno-rtti is removed from llvm-config --cppflags. * We could selectively add / remove rtti from various components, however mixing rtti and non-rtti code is tricky and could introduce missing symbols. * This needs impact tested.

* gallivm: handle explicit derivatives for cubemapsRoland Scheidegger2013-10-103-56/+235
| | | | | | | | | | | | | | | | | | | | They need some special handling. Quite complicated. Additionally, use the same code for implicit derivatives too if no_rho_approx and no_quad_lod is set, because it seems while generally it should be ok to use per quad lod for implicit derivatives there's at least some test which insists that in case of cubemaps the shared lod value MUST come from a pixel inside the primitive (due to the derivatives becoming different if a different larger major axis is chosen). v2: based on Brian's feedback, clean up code a bit. And use sign bit of major axis instead of pre-select s/t/r sign for coord mirroring (which should be the same in the end, saves 2 ands). Also fix two bugs with select/mirror of derivatives, the minor axes need to use major axis sign as well (instead of major derivative axis sign), and don't mistakenly use absolute values of major derivative and inverse major values.

* gallivm: ignore rho approximation for cube mapsRoland Scheidegger2013-10-101-30/+20
| | | | | | | | | | | | | | There's two reasons for this: 1) even when ignoring rho approximation for cube maps, the result is still not correct, but it's better as the max error at edges is now sqrt(2) instead of 2 (which was a full mip level), same as it is for ordinary 2d maps when doing rho approximations (so the error actually goes from factor 2 at edges and sqrt(2) completely inside a face to sqrt(2) at edges and 0 inside a face). 2) I want to repurpose rho_no_approx for cubemaps for fully correct cubemap derivatives (so don't need yet another debug var).

| | | | | | | | | | | | Technically without seamless filtering enabled GL allows any wrap mode, which made sense when supporting true borders (can get seamless effect with border and CLAMP_TO_BORDER), but gallium doesn't support borders and d3d9 requires wrap modes to be ignored and it's a pain to fix up the sampler state (as it makes it texture dependent). It is difficult to imagine a situation where an app really wants another behavior so just cheat here. (It looks like some graphics hw (intel) actually requires this too hence it should be safe.)
