Rewrite a bunch of constructors. It's now important that the first
...
constructor for any given type be the one that takes the most parameters
as this is the constructor that'll be used when there's no perfect match
to the caller's arguments.
See the _slang_adapt_call() function for details.

_slang_gen_function_call_name() now tries to adapt function calls (expand
...
vectors, insert casts) when a perfect match isn't found.
2007-01-17 16:14:03 -07:00
eabb7e66bd
New _slang_adapt_call() function.
...
This is used to modify function calls (when possible) to make the arguments
map to the function parameters. This includes "unrolling" vector types
and doing casts.
Example:
vec2 v2 = vec2(1.2, 3.4)
ivec3 iv = ivec3(false, v2);
Is converted into:
ivec3 iv = ivec3(int(false), int(v2[0]), int(v2[1]))
