* glsl 1.30: Fix numerical instabilities in asinhPaul Berry2011-09-281-4/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The formula we were previously using for asinh: asinh x = ln(x + sqrt(x * x + 1)) is numerically unstable: when x is a large negative value, the quantity x + sqrt(x * x + 1) is a small positive value (on the order of 1/(2|x|)). Since the logarithm function is very sensitive in this range, any error in the computation of the square root manifests as a large error in the result. This patch changes to the equivalent formula: asinh x = sign(x) * ln(abs(x) + sqrt(x * x + 1)) which is only slightly more expensive to compute, and is numerically stable for all x. Fixes piglit tests spec/glsl-1.30/execution/built-in-functions/[fv]s-asinh-*.

* i965: don't intepolate clip distances on pre-GEN6.Paul Berry2011-09-281-2/+8
| | | | | | | | | | | | | On pre-GEN6 chips, the VUE slots set aside for clip distance aren't actually used, so there is no reason for the clipper to waste time interpolating them. When commit 62bad54727690bff5ed42a74272e7822fd36cdb6 changed the enum value used to represent these VUE slots, that caused the clipper to start interpolating them as an accidental side effect. This patch reverts to the old clipper behavior. Reviewed-by: Kenneth Graunke <[email protected]>
* i965 new VS: Fix bugs in pre-GEN6 psiz/flags computationPaul Berry2011-09-281-5/+5
| | | | | | | | | | | | | | | | | | This patch corrects two errors in the computation of the psiz/flags VUE slot on pre-GEN5 when using the new VS backend: - The clip flags (which should be stored in the w component of the first VUE slot) were being accidentally duplicated in all other components of that VUE slot, causing partially clipped triangles to sometimes disappear completely. - The OR instruction wasn't being stored in "inst", causing the BRW_PREDICATE_NORMAL flag to be applied to the wrong instruction. This patch fixes regressions in clipping behavior when using shaders on GEN4-5. Reviewed-by: Kenneth Graunke <[email protected]>
* i965 new VS: Fix src_reg(uint32_t) constructor.Paul Berry2011-09-281-1/+1
| | | | | | | | | This constructor was storing its argument in the wrong field of the "imm" enum, resulting in it being converted to a float when it should have remained an unsigned integer. This was preventing clipping from working properly on pre-GEN6. Reviewed-by: Kenneth Graunke <[email protected]>
* i965 new VS: don't share clip plane constants in pre-GEN6Paul Berry2011-09-286-43/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | In pre-GEN6, when using clip planes, both the vertex shader and the clipper need access to the client-supplied clip planes, since the vertex shader needs them to set the clip flags, and the clipper needs them to determine where to insert new vertices. With the old VS backend, we used a clever optimization to avoid placing duplicate copies of these planes in the CURBE: we used the same block of memory for both the clipper and vertex shader constants, with the clip planes at the front of it, and then we instructed the clipper to read just the initial part of this block containing the clip planes. This optimization was tricky, of dubious value, and not completely working in the new VS backend, so I've removed it. Now, when using the new VS backend, separate parts of the CURBE are used for the clipper and the vertex shader. Note that this doesn't affect the number of push constants available to the vertex shader, it simply causes the CURBE to occupy a few more bytes of URB memory. The old VS backend is unaffected. GEN6+, which does clipping entirely in hardware, is also unaffected. Reviewed-by: Kenneth Graunke <[email protected]>
* i965: Fix a hardcoded user clip plane count.Paul Berry2011-09-281-1/+1
| | | | | | | | | Now that i965 supports 8 clip planes instead of 6, the size of the brw_vs_compile::userplane array needs to be increased to 8. Changed the array size to MAX_CLIP_PLANES so that if the number changes again in the future, this array size won't be missed. Reviewed-by: Kenneth Graunke <[email protected]>
* i965: allow for nonconsecutive elements of gl_ClipDistance to be enabled.Paul Berry2011-09-283-4/+38
| | | | | | | | | | | | | | | | | | | | | | When using user-defined clipping planes, the i965 driver compacts the array of clipping planes so that disabled clipping planes do not appear in it--this saves precious push constant space and makes it easier to generate the pre-GEN6 clip program. As a result, when enabling clipping planes in GEN6+ hardware, we always enable clipping planes 0 through n-1 (where n is the number of clipping planes enabled), regardless of which clipping planes the user actually requested. However, we can't do this when using gl_ClipDistance, because it would be prohibitively complex to compact the gl_ClipDistance array inside the user-supplied vertex shader. So, when enabling clipping planes in GEN6+ hardware, if gl_ClipDistance is in use, we need to pass the user-supplied enable flags directly through to the hardware rather than just enabling the first n planes. Fixes Piglit test vs-clip-distance-enables. Reviewed-by: Kenneth Graunke <[email protected]>
* i965: Use 4 bits to store nr_userclip in brw_clip.h.Paul Berry2011-09-281-2/+1
| | | | | | | | | | | | | | | Since the i965 driver supports 8 clipping planes now, we need 4 bits to store the number of user clipping planes, not 3. In theory this isn't strictly necessary, since brw_clip.h is only used on pre-GEN6, and pre-GEN6 only advertises support for 6 clipping planes, but it seems wise to err on the safe side. In the process I removed the pad0 element of struct brw_clip_prog_key--it doesn't seem necessary because the compiler automatically inserts padding if needed.
