In this case, we say an entrypoint is supported if ANY of the extensions is supported. This is because, in the XML, entrypoints don't require extensions so much as extensions require entrypoints. Reviewedby: Samuel Iglesias Gonsálvez <siglesias@igalia.com>

Jason Ekstrand authored
The original string map assumed that the mapping from strings to entrypoints was a bijection. This will not be true the moment we add entrypoint aliasing. This reworks things to be an arbitrary map from strings to nonnegative signed integers. The old one also had a potential bug if we ever had a hash collision because it didn't do the strcmp inside the lookup loop. While we're at it, we break things out into a helpful class.

Our previous handling of barriers always used the big hammer and didn't correctly emit memory barriers when specified along with a control barrier. This commit completely reworks the way we emit barriers to make things both more precise and more correct.

When looking up known glsl_type instances in the various hash tables, we end up leaking the key instances used for the lookup, as the glsl_type constructor allocates memory on the global mem_ctx. This patch changes glsl_type to manage its own memory, which fixes the leak and also allows getting rid of the global mem_ctx and its mutex. v2: remove lambda usage (Tapani) (+keep ASSERT_BITFIELD_SIZE, modify dummy ctor to initialize mem_ctx) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=104884 Cc: mesastable@lists.freedesktop.org Signedoffby: Simon Hausmann <simon.hausmann@qt.io> Signedoffby: Tapani Pälli <tapani.palli@intel.com> Reviewedby: Emil Velikov <emil.velikov@collabora.com> Reviewedby: Kenneth Graunke <kenneth@whitecape.org>

These transformations are inexact because section 4.7.1 (Range and Precision) says: Operations and builtin functions that operate on a NaN are not required to return a NaN as the result. The fmin or fmax might not return NaN in cases where the original expression would be required to return NaN.
