/**
 * \file builtin_functions.cpp
 *
 * Support for GLSL built-in functions.
 *
 * This file is split into several main components:
 *
 * 1. Availability predicates
 *
 *    A series of small functions that check whether the current shader
 *    supports the version/extensions required to expose a built-in.
 *
 * 2. Core builtin_builder class functionality
 *
 * 3. Lists of built-in functions
 *
 *    The builtin_builder::create_builtins() function contains lists of all
 *    built-in function signatures, where they're available, what types they
 *    take, and so on.
 *
 * 4. Implementations of built-in function signatures
 *
 *    A series of functions which create ir_function_signatures and emit IR
 *    via ir_builder to implement them.
 *
 * 5. External API
 *
 *    A few functions the rest of the compiler can use to interact with the
 *    built-in function module.  For example, searching for a built-in by
 *    name and parameters.

/**
 * Unfortunately, some versions of MinGW produce bad code if this file
 * is compiled with -O2 or -O3.  The resulting driver will crash in random
 * places if the app uses GLSL.
 * The work-around is to disable optimizations for just this file.  Luckily,
 * this code is basically just executed once.
 *
 * MinGW 4.6.3 (in Ubuntu 13.10) does not have this bug.
 * MinGW 5.3.1 (in Ubuntu 16.04) definitely has this bug.
 * MinGW 6.2.0 (in Ubuntu 16.10) definitely has this bug.
 * MinGW 7.3.0 (in Ubuntu 18.04) does not have this bug.  Assume versions before 7.3.x are buggy
