Support writing initializers using HLSL literal syntax Instead of using constructor functions to initialize variables, it is better to use literal initializer syntax provided by HLSL when it is possible. This way shader complexity is reduced and constant array initialization doesn't have to go through as many AST transformations. Before this patch, vec4 initialization would result in the following kind of HLSL: float4 f = float4(1.0, 2.0, 3.0, 4.0); After this patch, it will be: float4 f = {1.0, 2.0, 3.0, 4.0}; Before this patch, vec2 array initialization would result in the following kind of HLSL: float2 f[2] = {0, 0, 0, 0}; angle_construct_into_2_float2(f, float2(1.0, 2.0), float2(3.0, 4.0)); After this patch, it will be: float2 f[2] = {1.0, 2.0, 3.0, 4.0}; BUG=angleproject:1094 BUG=541551 TEST=WebGL conformance tests Change-Id: I9816a8d95a2cba3964922f6b561862d478da6145 Reviewed-on: https://chromium-review.googlesource.com/311160 Reviewed-by: Zhenyao Mo <zmo@chromium.org> Tested-by: Olli Etuaho <oetuaho@nvidia.com>
