* ra: Don't use regs as the ralloc context.Matt Turner2014-12-011-1/+1
| | | | | | | | | | The i965 backends pass something out of 'screen', which is allocated per-process, making using this as a ralloc context not thread-safe. All callers ra_alloc_interference_graph() already ralloc_free() its return value. Reviewed-by: Jason Ekstrand <[email protected]>
* 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/u_atomic: Add a simple test.José Fonseca2014-12-012-0/+146
| | | | | | | | | | | | | It was much easier for me to verify things build and run as expected with this simple test, than building and testing whole Mesa. With scons the test can be build and run merely by doing: scons u_atomic_test Building the test with autotools is left as a future exercise. 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!

| | | | | | | | | | | | | | | | | This hash table is used in core Mesa, the GLSL compiler, and the i965 driver, which makes it a good candidate for the new src/util module. It's much faster than program/hash_table.[ch] (see commit 6991c2922f5 for data), and José's u_hash_table.c has a comment saying Gallium should probably consider switching to a linear probing hash table at some point. So this seems like the best candidate for a shared data structure.

* util: Move ralloc to a new src/util directory.Kenneth Graunke2014-08-047-0/+1095
For a long time, we've wanted a place to put utility code which isn't directly tied to Mesa or Gallium internals. This patch creates a new src/util directory for exactly that purpose, and builds the contents as libmesautil.la. ralloc seemed like a good first candidate. These days, it's directly used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl didn't make much sense.
