* draw/llvm: reduce memory usageZack Rusin2014-04-245-20/+27

| | | | | | | | Mostly for consistency; as MSVC's static source code analysis doesn't seem to rely on assertions, but instead on different kind of source annotations( http://msdn.microsoft.com/en-us/library/hh916383.aspx ). Reviewed-by: Brian Paul <[email protected]>

| | | | | | | | | | | | | | | | warning. Now that _debug_assert_fail() has the noreturn attribute, it is better that execution truly never returns. Not just for sake of silencing the warning, but because the code at the return IP address may be invalid or lead to inconsistent results. This removes support for the GALLIUM_ABORT_ON_ASSERT debugging environment variable, but between the usefulness of GALLIUM_ABORT_ON_ASSERT and better static code analysis I think better static code analysis wins.

* llvmpipe: add support for b5g6r5_srgbRoland Scheidegger2014-03-213-5/+25
| | | | | | | | | | | | | The conversion code for srgb was tuned for n x 4x8bit AoS -> 4 x nxfloat SoA (and vice versa), fix this to handle also 16bit 565-style srgb formats. Still not really all that generic, things like r10g10b10a2_srgb or r4g4b4a4_srgb wouldn't work (the latter trivial to fix, the former would not require more work to not crash but near certainly need some higher precision calculation) but not needed right now. The code is not fully optimized for this (could use more direct calculation instead of expanding to 8-bit range first) but should be good enough. Reviewed-by: Jose Fonseca <[email protected]>
* gallium: add b5g6r5 srgb formatRoland Scheidegger2014-03-213-4/+19
| | | | | | | | | | | | | | | GL generally doesn't seem to allow srgb formats with less (or more) than 8 bit for the rgb channels, though some hw could easily do it (typically for formats with up to 10 bits for the rgb channels, at least for formats with less than 8 bits support is likely widespread even). While it may be true there aren't really any benefits for such formats, we need for it for d3d, though luckily only for b5g6r5_srgb it seems. So add this format along with the util code for conversion - since that util code is heavily tuned for 8bit srgb this isn't really all that well optimized and rounding doesn't seem right but at least it should give some halfway meaningful results.

* gallivm: optimize repeat linear npot code in the aos int pathJeff Muizelaar2014-03-141-12/+62
| | | | | | Similar to the other cases, shift some weight/coord calculations to int space. This should be slightly faster (on x86 sse it should actually safe one instruction, and generally int instructions are cheaper).
* gallivm: use correct rounding for nearest wrap mode (in the aos int path)Roland Scheidegger2014-03-141-29/+9
| | | | | | | | | | | | | The previous code used coords which were calculated as (int) (f_coord * tex_size * 256) >> 8. This is not only unnecessarily complex but can give the wrong texel due to rounding for negative coords (as an example, after denormalization coords from -1.0 to 0.0 should give -1, but this will give -1 for numbers from -1.0-1/256 - 0.0-1/256. Instead, juse use ifloor, dropping the shift stuff. Unfortunately, this will most likely be slower - with arch rounding available it shouldn't be too bad (trades a int shift for a round but also saves an int mul (which is shared by all coords) but otherwise it's a mess.
* gallivm: use correct rounding for linear wrap mode (in the aos int path)Jeff Muizelaar2014-03-141-6/+8
| | | | | | | | | | | | | | | | | | | The previous method for converting coords to ints was sligthly inaccurate (effectively losing 1bit from the 8bit lerp weight). This is probably especially noticeable when trying to draw a pixel-aligned texture. As an example, for a 100x100 texture after dernormalization the texture coords in this case would turn up as 0.5, 1.5, 2.5, 3.5, 4.5, ... After the mul by 256, conversion to int and 128 subtraction, they end up as 0, 256, 512, 768, 1024, ... which gets us the correct coords/weights of 0/0, 1/0, 2/0, 3/0, 4/0, ... But even LSB errors (which are unavoidable) in the input coords may cause these coords/weights to be wrong, e.g. for a coord of 3.49999 we'd get a coord/weight of 2/255 instead. Fix this by using round-to-nearest int instead of FPToSi (trunc). Should be equally fast on x86 sse though other archs probably suffer a little.

* gallium: allow setting of the internal stream output offsetZack Rusin2014-03-0710-21/+29
| | | | | | | | | | | | | | | | D3D10 allows setting of the internal offset of a buffer, which is in general only incremented via actual stream output writes. By allowing setting of the internal offset draw_auto is capable of rendering from buffers which have not been actually streamed out to. Our interface didn't allow. This change functionally shouldn't make any difference to OpenGL where instead of an append_bitmask you just get a real array where -1 means append (like in D3D) and 0 means do not append.

| | | | | | | | | | | | | | Because in draw we always inject position at slot 0 whenever fragment shader would take the maximum number of inputs (32) it meant that we had PIPE_MAX_ATTRIBS + 1 slots to translate, which meant that we were crashing with fragment shaders that took the maximum number of attributes as inputs.

* draw/llvm: fix generation of the VS with GS presentZack Rusin2014-03-041-7/+7
| | | | | | | | | | | | | | | | | draw_current_shader_* functions return a final output when considering both the geometry shader and the vertex shader. But when code generating vertex shader we can not be using output slots from the geometry shader because, obviously, those can be completely different. This fixes a number of very non-obvious crashes. A side-effect of this bug was that sometimes the vertex shading code could save some random outputs as position/clip when the geometry shader was writing them and vertex shader had different outputs at those slots (sometimes writing garbage and sometimes something correct).
