Martin Whitaker 5929a00845 Handle uninitialised variables in constant user functions. 2013-03-24 14:40:44 -07:00
Martin Whitaker 5d7558b5e0 Fix assigned vector size in constant user functions.
When assigning to a bit/logic variable, the RHS expression value
must be trimmed to match the size of the variable.

Martin Whitaker e8d4039175 Fix implicit casts in assignments (part 4).
This patch fixes a few issues/bugs that showed up when testing the
fixes for implicit casts:

1. Make the compile-time implementation of $abs, $min, and $max match
   the run-time behaviour (system functions can't be polymorphic).

2. Correctly set the type (signed/unsigned) of the result of an
   assignment inside a constant user function (the LHS should not
   inherit the type of the RHS).

3. Fix a bug in the verinum(double) constructor (insufficient bits
   were allocated in the case where the double value rounded up to
   the next power of two).

Martin Whitaker 8b70fefa59 Refactor eval_tree debug code.
This just pulls the eval_tree debug message generation into one place.

Martin Whitaker af91920a17 Add support for system function calls in constant functions. 2013-02-08 11:19:26 -08:00
Martin Whitaker 89244e0f70 Add support for concatenation operations in constant functions.
Also fix a compiler crash when attempting to evaluate a function
which has no valid statement(s) (due to earlier compilation errors).

Cary R 5830e65829 Fix space issues. 2013-02-04 12:17:41 -08:00
Martin Whitaker f3a51fdfd1 Factor out some common eval_tree code.
The eval_tree() function is identical in most of the NetEBinary and
NetEUnary sub-classes.

Martin Whitaker afd23d13d5 Add support for unary operators in constant user functions.
This patch implements the evaluate_function method for the NetEUnary
and NetEUReduce classes.

Martin Whitaker 11f479e028 Add support for all binary operators in constant user functions.
This patch implements the evaluate_function method for the NetEBBits,
NetEBDiv, NetEBLogic, NetEBMinMax, and NetEBPow classes. It also
factors out some common code into the NetEBinary class.
