* android: fix the building rules for Android 5.0Chih-Wei Huang2015-04-221-2/+2
| | | | | | | | | | | | | | | | | Android 5.0 allows modules to generate source into $OUT/gen, which will then be copied into $OUT/obj and $OUT/obj_$(TARGET_2ND_ARCH) as necessary. Modules will need to change calls to local-intermediates-dir into local-generated-sources-dir. The patch changes local-intermediates-dir into local-generated-sources-dir.

* ralloc: Implement a new ralloc_adopt() API.Kenneth Graunke2015-04-022-0/+33
| | | | | | | | | | | | | | | | | | | | | ralloc_adopt() reparents all children from one context to another. Conceptually, ralloc_adopt(new_ctx, old_ctx) behaves like this pseudocode: foreach child of old_ctx: ralloc_steal(new_ctx, child) However, ralloc provides no way to iterate over a memory context's children, and ralloc_adopt does this task more efficiently anyway. One potential use of this is to implement a memory-sweeper pass: first, steal all of a context's memory to a temporary context. Then, walk over anything that should be kept, and ralloc_steal it back to the original context. Finally, free the temporary context. This works when the context is something that can't be freed (i.e. an important structure). Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | The SSE 4.1 ROUND instructions let us implement roundeven directly. Otherwise we assume that the rounding mode has not been modified (as we do in the rest of Mesa) and use rint(). glibc uses the ROUND instruction in rint() after a cpuid check.

* mesa: Replace _mesa_round_to_even() with _mesa_roundeven().Matt Turner2015-03-182-0/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
