* glsl: improve accuracy of atan()Erik Faye-Lund2014-10-101-10/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our current atan()-approximation is pretty inaccurate at 1.0, so let's try to improve the situation by doing a direct approximation without going through atan. This new implementation uses an 11th degree polynomial to approximate atan in the [-1..1] range, and the following identitiy to reduce the entire range to [-1..1]: atan(x) = 0.5 * pi * sign(x) - atan(1.0 / x) This range-reduction idea is taken from the paper "Fast computation of Arctangent Functions for Embedded Applications: A Comparative Analysis" (Ukil et al. 2011). The polynomial that approximates atan(x) is: x * 0.9999793128310355 - x^3 * 0.3326756418091246 + x^5 * 0.1938924977115610 - x^7 * 0.1173503194786851 + x^9 * 0.0536813784310406 - x^11 * 0.0121323213173444 This polynomial was found with the following GNU Octave script: x = linspace(0, 1); y = atan(x); n = [1, 3, 5, 7, 9, 11]; format long; polyfitc(x, y, n) The polyfitc function is not built-in, but too long to include here.

| | | | | | | | | | | | | | | | | | Historically, we've implemented the rules for overriding built-in functions by creating multiple ir_functions and relying on the symbol table to hide the one containing built-in functions. That works, but has a few drawbacks, so the next patch will change it. Instead, we'll have a single ir_function for a particular name, which will contain both built-in and user-defined signatures. Passing an extra parameter to matching_signature makes it easy to ignore built-ins when they're supposed to be hidden.
