ES31: Add atomic memory functions for SSBO Due to SSBO is translated to RWByteAddressBuffer in HLSL, the corresponding atomic memory functions atomic* will be translated to RWByteAddressBuffer.Interlocked*. The translation is like below: atomicAdd(instanceName.data[0], 5u); // becomes uint _ssbo_atomicAdd_uint(RWByteAddressBuffer buffer, uint loc, uint value) { uint original_value; buffer.InterlockedAdd(loc, value, original_value); return original_value; } _ssbo_atomicAdd_uint(_instanceName, 0 + 16 * 0, 5); Bug: angleproject:1951 Change-Id: If2af8bedb67a4135b443d2512d43c6058a78888d Reviewed-on: https://chromium-review.googlesource.com/c/1370676 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Jiajia Qin <jiajia.qin@intel.com>
