* mesa: Replace _mesa_round_to_even() with _mesa_roundeven().Matt Turner2015-03-181-22/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eric's initial patch adding constant expression evaluation for ir_unop_round_even used nearbyint. The open-coded _mesa_round_to_even implementation came about without much explanation after a reviewer asked whether nearbyint depended on the application not modifying the rounding mode. Of course (as Eric commented) we rely on the application not changing the rounding mode from its default (round-to-nearest) in many other places, including the IROUND function used by _mesa_round_to_even! Worse, IROUND() is implemented using the trunc(x + 0.5) trick which fails for x = nextafterf(0.5, 0.0). Still worse, _mesa_round_to_even unexpectedly returns an int. I suspect that could cause problems when rounding large integral values not representable as an int in ir_constant_expression.cpp's ir_unop_round_even evaluation. Its use of _mesa_round_to_even is clearly broken for doubles (as noted during review). The constant expression evaluation code for the packing built-in functions also mistakenly assumed that _mesa_round_to_even returned a float, as can be seen by the cast through a signed integer type to an unsigned (since negative float -> unsigned conversions are undefined). rint() and nearbyint() implement the round-half-to-even behavior we want when the rounding mode is set to the default round-to-nearest. The only difference between them is that nearbyint() raises the inexact exception. This patch implements _mesa_roundeven{f,}, a function similar to the roundeven function added by a yet unimplemented technical specification (ISO/IEC TS 18661-1:2014), with a small difference in behavior -- we don't bother raising the inexact exception, which I don't think we care about anyway. At least recent Intel CPUs can quickly change a subset of the bits in the x87 floating-point control register, but the exception mask bits are not included. rint() does not need to change these bits, but nearbyint() does (twice: save old, set new, and restore old) in order to raise the inexact exception, which would incur some penalty.

* mesa: Remove rounding bias in _mesa_float_to_half()Chad Versace2013-01-241-29/+37
| | | | | | | | | | | | | | | | | | | | | | | Not all float32 values can be exactly represented as a float16. _mesa_float_to_half() rounded such intermediate float32 values to zero by truncating unrepresentable bits in the mantissa. This patch improves _mesa_float_to_half() by rounding intermediate float32 values to the nearest float16; when the float32 is exactly between two float16 values we round to the one with an even mantissa. This behavior is preferred over the old behavior because: - It has reduced bias relative to the old behavior. - It reproduces the behavior of real hardware: opcode F32TO16 in Intel's GPU ISA. - By reproducing the behavior of the GPU (at least on Intel hardware), compile-time evaluation of constant packHalf2x16 GLSL expressions will result in the same value as if the expression were executed on the GPU.

| | | | | | | | | | | | | | | | The i965 driver already had a function to count bits in a 64-bit uint (brw_count_bits()), but it was buggy (it only counted the bottom 32 bits) and it was clumsy (it had a strange and broken fallback for non-GCC-like compilers, which fortunately was never used). Since Mesa already has a _mesa_bitcount() function, it seems better to just create a _mesa_bitcount_64() function rather than special-case this in the i965 driver.
