Hello, This patch series implements the support for VK_KHR_shader_float_controls for Intel platforms (Broadwell and later).
This extension enables efficient use of floating-point computations through the ability to query and override the implementation's default behavior for rounding modes, denormals, signed zero, and infinity. This patch series depends on Iago's patch series implementing VK_KHR_shader_float16_int8 support on ANV [0] for the float16 support. If you want to test this patch series, you can clone this branch (it already includes Iago's patch series): $ git clone -b siglesias/VK_KHR_shader_float_controls \ https://github.com/Igalia/mesa.git Thanks!
