This instruments the plumbing for the extension without adding any functionality or exposing the extensions string. The extension text is also updated to reflect the new entry point design and naming. Also this corrects a few mistakes. This will be followed up by the tests (which won't run) and then the extension functionality in ANGLE. BUG=angleproject:1897 Change-Id: I5b009e23bc27da06b067375525bd6fc574027702

OpenGL ES Extension #??
|
|
|
|
Dependencies
|
|
|
|
OpenGL ES 3.0 is required.
|
|
|
|
This extension is written against the wording of the OpenGL ES
|
|
3.0 specification.
|
|
|
|
Overview
|
|
|
|
With the program cache enabled, created OpenGL ES contexts will use an
|
|
internal program binary cache to save linking time. The extension allows the
|
|
application to determine if a particular Context has this feature enabled.

Accepted by the <cap> parameter to IsEnabled and the <pname> parameter to
|
|
GetBooleanv, GetIntegerv, GetFloatv, and GetInteger64v:
|
|
|
|
PROGRAM_CACHE_ENABLED_ANGLE 0x93AC
|
|
|
|
Additions to the OpenGL ES Specification:
|
|
|
|
Add to section 2.12.3 (Program Objects), p. 52, after paragraph 4:
|
|
|
|
Contexts with PROGRAM_CACHE_ENABLED_ANGLE set to TRUE will query the
|
|
internal program cache on any LinkProgram call, and re-use program binaries
|
|
if matching values are found. LinkProgram will succeed in this case. If the
|
|
binary load fails for any reason, LinkProgram will fall back to linking
|
|
normally.
