here are some more typos to fix:
were -> where
exerises -> exercises
comparision -> comparison
againsts -> against
lol, thanks.
For me running this throws following assert:
shader_runner: ../src/compiler/glsl/ir.cpp:491:
ir_expression::ir_expression(int, ir_rvalue*, ir_rvalue*): Assertion
`op0->type == op1->type' failed.
Is this the issue?
Seems to be a bug with do_tree_grafting()
Either that or in opt_algebraic. It's turning lessThan(a + b, 0) into a
< -b, but it's loosing all the swizzles and the sizes.
Ah yes you are right. It does seem to be opt_algebraic() that is the cause.
