juj:more_webgl_code_size_opts

Feb 7, 2019

Commits on Feb 6, 2019

Micro-optimize WebGL support: each GL object table stores null at index 0, so testing "id ? GL.table[id] : null" is redundant. Optimizes -21 bytes (-0.13%) in minimal WebGL demo

Micro-optimize WebGL support: Collapse WebGL 1 bufferData() call to one. Saves -17 bytes (-0.11%) on minimal WebGL demo

Micro-optimize WebGL library: save -7 bytes (-0.11%) on redundant null check

Micro-optimize WebGL library: simplify uniform array bracket parsing. Reduces minimal WebGL demo by -57 bytes (-0.92%)

Micro-optimize WebGL support library: avoid Math.max() to save -5 bytes (-0.03%) on minimal WebGL demo

Micro-optimize WebGL library: GL.getSource() smaller, saves -8 bytes (-0.14%)
juj
committed
Micro-optimize WebGL glBindAttribLocation and glGetUniformBlockIndex. Optimizes -4 bytes (0.07%)
juj
committed
Micro-optimize WebGL glLinkProgram: Closure is for some reason unable to collapse redundant assignments. Saves -16 bytes (-0.31%) in minimal WebGL demo.
juj
committed
Micro-optimize WebGL library: Power of 2 rounding up when computing unpack alignment. Saves -5 bytes (-0.10%). Also use GL_ASSERTIONS instead of ASSERTIONS in WebGL library.

Micro-optimize WebGL context activation. Saves -18 bytes (0.12%)

Micro-optimize WebGL object creation

Revert unreadable '9e9' and 'if (x > max) max = x;' optimizations from srx/library_gl.js. Regresses hello webgl by 10 bytes (+0.17%)
