4b6fd39c89 Add a virtual clone() method to ir_instruction. 
This will be used by function inlining, the linker, and avoiding double
usage of the LHS deref chains in ++, *=, and similar operations.

ac95f2f8c8 Include stdio.h and stdlib.h everywhere, and don't cook our own #define NULL. 2010-06-22 12:30:55 -07:00

f8b88bea0f ir_constant_visitor: Type of constant result is same as original expression 
The type of the resulting constant must be the same as the type of the
original expression.  The changes to the code require that the case
where an unhandled expression is received, and there really shouldn't
be any of these, must be an exit point.

083d75a942 ir_constant_visitor: Types of ir_binop_{equal,nequal} must match 
The types must match exactly, so there is no reason to check the types here.

d6a32d4b54 ir_constant_visitor: Add support for dFdx and dFdy operations. 
If the argument is a constant expression...it's not changing per pixel,
so the result is simply 0.

fad607a9be Add ir_loop to represent loops 
This touches a lot of files because everything derived from ir_visitor
has to be updated.  This is the primary disadvantage of the visitor pattern.
