| | | | | | | | We need to build certain parts of Mesa (namely gallium, llvmpipe, and therefore util) with Windows SDK 7.0.7600, which includes MSVC 2008. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
* util/u_atomic: Add new macro p_atomic_addCarl Worth2015-02-091-0/+16
| | | | | | | | | | | | | This provides for atomic addition, which will be used by an upcoming shader-cache patch. A simple test is added to "make check" as well. Note: The various O/S functions differ on whether they return the original value or the value after the addition, so I did not provide an add_return() macro which would be sensitive to that difference.

* util/u_atomic: Fix the unlocked implementation.José Fonseca2014-12-011-6/+6
| | | | | | | | | | | | | | | | | | It was totally broken: - p_atomic_dec_zero() was returning the negation of the expected value - p_atomic_inc_return()/p_atomic_dec_return() was post-incrementing/decrementing, hence returning the old value instead of the new - p_atomic_cmpxchg() was returning the new value on success, instead of the old It is clear this never used in the past. I wonder if it wouldn't be better to yank it altogether. Reviewed-by: Matt Turner <[email protected]>
* util: Make u_atomic.h typeless.Matt Turner2014-12-011-113/+93
| | | | | | | | | | | | like how C11's stdatomic.h provides generic functions. GCC's __sync_* builtins already take a variety of types, so that's simple. MSVC and Sun Studio don't, but we can implement it with something that looks a little crazy but is actually quite readable. Thanks to Jose for some MSVC fixes!
