* gallium/tgsi: move tgsi_exec.h header out of draw_context.hDave Airlie2016-04-262-1/+1
| | | | | | | | | It gets annoying that changing the tgsi exec rebuilds the state tracker unnecessarily. Putting this include into draw_gs.h which uses it causes a lot less rebuilds. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* gallivm: make sampling more robust against bogus coordinatesRoland Scheidegger2016-04-263-13/+43
| | | | | | | | | | | | | | | | | | | | | | Some cases (especially these using fract for coord wrapping) did not handle NaNs (or Infs) correctly - the following code assumed the fract result could not be outside [0,1], but if the input is a NaN (or +-Inf) the fract result was NaN - which then could produce out-of-bound offsets. (Note that the explicit NaN behavior changes for min/max on x86 sse don't result in actual changes in the generated jit code, but may on other architectures. Found by looking through all the wrap functions.) This fixes https://bugs.freedesktop.org/show_bug.cgi?id=94955 No piglit changes.

* gallivm: fix bogus argument order to lp_build_sample_mipmap functionRoland Scheidegger2016-04-211-2/+2
| | | | | | | | | | | | | | | Screwed up since 0753b135f6e83b171d8a1b08aea967374f3542bc. (Only an issue with different min/mag filters, and then only in some cases, which is probably why it went unnoticed for quite a while. The effect should have simply been nearest mip filter instead of linear, iff min was nearest, mag was linear, and all pixels hit the mignifying path.) Fixes a bunch of dEQP failures.

| | | | | | | | | | | | | | | | Add support for lowering FLR and CEIL to FRC/SUB and FRC/ADD instructions for GPUs that support FRC but not FLR or CEIL. Since these uses FRC, it is invalid to ask for FLR or CEIL to be lowered along with FRC, so add an assert to catch this invalid configuration. We also need to deal with FLR instructions emitted by the lowering code. Fix these up with the FRC+SUB equivalent when FLR lowering is enabled.

* gallivm: use llvm.nearbyint instead of llvm.round.Roland Scheidegger2016-04-131-98/+1
| | | | | | | | | | | | | | | | We used to use sse roundps intrinsic directly, but switched to use the llvm intrinsics for rounding with e4f01da15d8c6ce3e8c77ff3ff3d2ce2574a3f7b. However, llvm semantics follows standard math lib round function which is specced to do roundNearestAwayFromZero but we really want roundNearestEven (moreoever, using round generates atrocious code since the cpu can't do it directly and it results in scalar calls to libm __roundf). So, use llvm.nearbyint instead, which does exactly the right thing, and even has the advantage of being available with llvm 3.3 too. (I've verified it actually generates a roundps instruction with llvm 3.3.) This fixes https://bugs.freedesktop.org/show_bug.cgi?id=94909 Reviewed-by: Jose Fonseca <[email protected]>

V4: Squash in the following patch: 'gallium/util: Ensure util_framebuffer_get_num_samples() is valid' Upon context creation, internal driver structures are malloc()'ed and memset() to zero them.
