* mesa: Fix uf10_to_f32() scale factor in the E == 0 and M != 0 case.Kenneth Graunke2016-08-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GL_EXT_packed_float, 2.1.B Unsigned 10-Bit Floating-Point Numbers: 0.0, if E == 0 and M == 0, 2^-14 * (M / 32), if E == 0 and M != 0, 2^(E-15) * (1 + M/32), if 0 < E < 31, INF, if E == 31 and M == 0, or NaN, if E == 31 and M != 0, In the second case (E == 0 and M != 0), we were multiplying the mantissa by 2^-20, when we should have been multiplying by 2^-19 (which is 2^(-14 + -5), or 2^-14 * 2^-5, or 2^-14 / 32). The previous section defines the formula for 11-bit numbers, which is: 2^-14 * (M / 64), if E == 0 and M != 0, In other words, we had accidentally copy and pasted the 11-bit code to the 10-bit case, and neglected to change the exponent. Fixes dEQP-GLES3.functional.pbo.renderbuffer.r11f_g11f_b10f_triangles when run with surface dimensions of 1536x1152 or 1920x1080.

* util: try to use SSE instructions with MSVC and 32-bit gccBrian Paul2016-08-171-3/+4
| | | | | | | | | | | | | The lrint() and lrintf() functions are pretty slow and make some texture transfers very inefficient. This patch makes a better effort at using those intrisics for 32-bit gcc and MSVC. Note, this patch doesn't address the use of SSE4.1 with MSVC. v2: get rid of the ROUND_WITH_SSE symbol, per Matt.

* util/rgb9e5: Get rid of the float754 unionJason Ekstrand2016-08-051-42/+27
| | | | | | | | | | | There are a number of reasons for this refactor. First, format_rgb9e5.h is not something that a user would expect to define such a generic union. Second, defining it requires checking for endianness which is ugly. Third, 90% of what we were doing with the union was float <-> uint32_t bitcasts and the remaining 10% can be done with a sinmple left-shift by 23.

| | | | | | | | | | | | | | | | | | | | | | Juha-Pekka found this back in May 2015: <[email protected]> From the discussion, obviously it would be preferable to make ralloc_size no longer return zeroed memory, but Juha-Pekka found that it would break Mesa. In <[email protected]>, Juha-Pekka mentioned that patches exist to fix i965 when ralloc_size is fixed to not zero memory, but the patches have not made their way to mesa-dev yet. For now, let's stop doing the double zeroing of rzalloc buffers. v2: * Move ralloc_size code to rzalloc_size, and add a comment as suggested by Ken.

* st/glsl_to_tgsi: reduce stack explosion in recursive expression visitorNicolai Hähnle2016-04-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | In optimized builds, visit(ir_expression *) experiences inlining with gcc that leads the function to have a roughly 32KB stack frame. This is a problem given that the function is called recursively. In non-optimized builds, the stack frame is much smaller, hence one gets crashes that happen only in optimized builds. Arguably there is a compiler bug or at least severe misfeature here. In any case, the easy thing to do for now seems to be moving the bulk of the non-recursive code into a separate function. This is sufficient to convince my version of gcc not to blow up the stack frame of the recursive part. Just to be sure, add the gcc-specific noinline attribute to prevent this bug from reoccuring if inliner heuristics change. v2: put ATTRIBUTE_NOINLINE into macros.h Cc: "11.1 11.2" <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95133 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=95026 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92850 Reviewed-by: Ilia Mirkin <[email protected]> Reviewed-by: Rob Clark <[email protected]>

| | | | | | | | | | | | | | | | | | These were being defined in SCons, but it's not practical: - we actually need to include Gallium headers from external source trees, with completely disjoint build infrastructure, and it's unsustainable to replicate the HAVE_xxx checks or even hard-coded defines across everywhere. - checking compiler version via command line doesn't really work due to Clang essentially being like a cameleon which can fake either GCC or MSVC There's no change for autoconf.

Could just use UNUSED directly, but MAYBE_UNUSED should be less confusing and is similar to what the Linux kernel has.

| | | | | | | | | | | | | | | | | | When we delete entries in the hash set, we mark them "deleted" by setting their key to the deleted_key, which points to a dummy deleted_key_value.
