Fix for br978 - assertion involving addition of $ivlh_to_unsigned() result.
...
$ivlh_to_unsigned, unlike $signed and $signed, can cause a reduction
in width. The shared PECallFunction::cast_to_width_ method did not
support this.

Fix for GitHub issue #37 - bug in expression width pruning.
...
If an expression contains a division, remainder, or right shift operation,
set the expression min_width to UINT_MAX to flag that the expression width
cannot be pruned. Using UINT_MAX ensures that the min_width won't change
as we continue to elaborate the expression.

Internally, treat the "$" as a special expression type that takes

The $size function is already implemented for dynamic queues and
it is easy enough to expand it for queues.

Fix for GitHub issue #18 : undef propagation of const multiplies is incorrect.
...
When an expression is elaborated, the compiler converts multiplies with
one constamt zero operand into a constant zero value. This is only valid
if the other operand is not a 4-state variable.
2014-02-27 19:30:28 +00:00
5dcd2e8957
Added width cap for unsized expressions.
...
Unsized expressions can expand to extremely large widths. Usually this
is actually a mistake in the source code, but it can lead to the compiler
temporarily using extremely large amounts of memory, or in the worst
case, crashing. This adds a cap on the width of unsized expressions (by
default 65536 bits, but overridable by the user), and causes a warning
message to be output when the cap is reached.
2014-02-27 19:20:20 +00:00
a3450bf856
Fixes for GitHub issues 13 and 15.
...
The verinum arithmetic operators now observe the standard Verilog
rules for calculating the result width if all operands are sized.
If any operand is unsized, the result is lossless, as before.
They also now all observe the standard rules for handling partially
undefined operands (if any operand bit is 'x', the entire result is
'x').
I've also added the unary '-' operator, and renamed v_not() to be
the unary '~' operator. This has allowed some simplification in
other parts of the compiler.
