Function for determining which basic constructor op to use

Both test, and if necessary spit out an error, to see if we are currently globally scoped. Returns true if the was an error.

Add branches.

Create loop nodes

For "if" test nodes. There are three children; a condition, a true path, and a false path. The two paths are in the nodePair.

returns true if the operator is for one of the constructors

Both test and if necessary, spit out an error, to see if the node is really an l-value that can be operated on this way. Returns true if the was an e

forks stdio to debug console so when you hit a breakpoint you can more easily see what test is running:

For each re-used semantic (e.g. TEXCOORD0) record the symbol for which it is output. This is so that you can specify the same semantic in multiple str

This function takes two aggragates, and merges them into a single one It does not nest the right inside the left, as ir_grow_aggregate would

Say whether or not an operation node changes the value of a variable. Returns true if state is modified.

Enforce non-initializer type/qualifier rules. Returns true if there was an error.

Do semantic checking for a variable declaration that has no initializer, and update the symbol table. Returns true if there was an error.

This is the sort function for parameter matching in findCompatible method below

Determine the GLSL attribute semantic for a given HLSL semantic

Look at a '.' field selector string and change it into offsets for a matrix.

Look at a '.' field selector string and change it into offsets for a vector.

This function promotes the function arguments contained in node to match the types from func.

Track whether errors have occurred.

For now, keep it simple: if it starts "gl_", it's reserved, independent of scope. Except, if the symbol table is at the built-in push-level, which i

Both test, and if necessary spit out an error, to see if the node is really an integer or convertible to an integer. Returns true if the was an error

Strip the semantic string of any modifiers
