Hans-Kristian Arntzen	e23c9ea700	Force complex loop in certain rare access chain scenarios. ... If we generate an access chain in a loop body, and it is consumed in the loop continue block, we have a problem because we cannot emit a temporary here holding the access chain reference. Force a complex loop body to workaround this exceptionally rare case.	2019-04-10 16:02:03 +02:00

Hans-Kristian Arntzen	eeb3f24991	Properly deal with sign-dependent GLSL opcodes. ... The GLSLstd450 spec is very lax about input signs, so we need to do the bitcasting dance to implement it correctly.	2019-03-27 12:20:53 +01:00
Hans-Kristian Arntzen	df3e21a762	Parser: Fix OpCompositeConstruct with OpUndef. ... Just treat any undefined argument as 0. It is risky to use the undefined variable as it might not lower to a true constant.	2019-03-27 10:51:23 +01:00
