Jamie Madill 5dd4ad89 2018-01-29T13:53:43 Vulkan: Add a perf test for the Pipeline cache. This micro-benchmark can be used to measure the performance impact of changing the Pipeline cache. For instance, we can check if changing the size of the hash key affects performance significantly. Also updates the build files so angle_perftests can see vulkan.h, and makes the Vulkan headers an explicit source set. This test currently shows that a lot of time is spent in PMurmurHash, with some time also spent in memcmp.

Jamie Madill cc6ac25e 2017-01-25T12:57:21 GLES: Expose OES_mapbuffer in GLES2 on GLES3. This extension is mandatory for EXT_map_buffer_range support. We can emulate it using GLES 3.0 core map functionality.

Yuly Novikov e3352f94 2016-08-12T20:40:14 Change angle_util to be a shared library So that there will be one instance of static thread synchronization variables in AndroidWindow. Previously there was one instance in lib_angle_deqp_gles2_tests__library and one in libangle_deqp_libgles2, resulting in AndroidWindow::initialize waiting forever. Also make the change in GYP build to fix standalone build, and fix rpath issues on Mac.

Jamie Madill f83cbc65 2016-01-22T15:27:21 Use std::random functions for test and samples RNG. These standard functions are much more powerful than the C random() routines. Use them to improve the random utils, and use a class to clean things up further. This fixes a problem I was having using random_utils where I was having trouble generating random 32 bit unsigned integers.
