* util/u_atomic: Add new macro p_atomic_addCarl Worth2015-02-092-0/+21
| | | | | | | | | | | | | 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/set: Do a full search when adding new itemsJason Ekstrand2015-02-071-6/+15
| | | | | | | | | | | | Previously, the set_insert function would bail early if it found a deleted slot that it could re-use. However, this is a problem if the key being inserted is already in the set but further down the list. If this happens, the element ends up getting inserted in the set twice. This commit makes it so that we walk over all of the possible entries for the given key and then, if we don't find the key, place it in the available free entry we found.

* util: Predicate the fpclassify fallback on !defined(__cplusplus)Jason Ekstrand2015-01-281-2/+12
| | | | | | | | | | | The problem is that the fallbacks we have at the moment don't work in C++. While we could theoretically fix the fallbacks it would also raise the issue of correctly detecting the fpclassify function. So, for now, we'll just disable it until we actually have a C++ user.

* configure: Add machinery for --enable-shader-cache (and --disable-shader-cache)Carl Worth2015-01-163-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't actually have the code for the shader cache just yet, but this configure machinery puts everything in place so that the shader cache can be optionally compiled in. Specifically, if the user passes no option (neither --disable-shader-cache, nor --enable-shader-cache), then this feature will be automatically detected based on the presence of a usable SHA-1 library. If no suitable library can be found, then the shader cache will be automatically disabled, (and reported in the final output from configure). The user can force the shader-cache feature to not be compiled, (even if a SHA-1 library is detected), by passing --disable-shader-cache. This will prevent the compiled Mesa libraries from depending on any library for SHA-1 implementation. Finally, the user can also force the shader cache on with --enable-shader-cache. This will cause configure to trigger a fatal error if no sutiable SHA-1 implementation can be found for the shader-cache feature. Bug fix by José Fonseca <[email protected]>: Fix to put conditional assignment in Makefile.am, not Makefile.sources to avoid breaking scons build. Note: As recommended by José, with this commit the scons build will not compile any of the SHA-1-using code. This is waiting for someone to write SConstruct detection of the available SHA-1 libraries, (and set the appropriate HAVE_SHA1_* variables). Reviewed-by: Matt Turner <[email protected]>

* util/hash_set: Rework the API to know about hashingJason Ekstrand2015-01-152-8/+51
| | | | | | | | | | | | | | | | | | | | | | | | Previously, the set API required the user to do all of the hashing of keys as it passed them in. Since the hashing function is intrinsically tied to the comparison function, it makes sense for the hash set to know about it. Also, it makes for a somewhat clumsy API as the user is constantly calling hashing functions many of which have long names. This is especially bad when the standard call looks something like _mesa_set_add(ht, _mesa_pointer_hash(key), key); In the above case, there is no reason why the hash set shouldn't do the hashing for you. We leave the option for you to do your own hashing if it's more efficient, but it's no longer needed. Also, if you do do your own hashing, the hash set will assert that your hash matches what it expects out of the hashing function. This should make it harder to mess up your hashing.
