Stephen Williams c14134aa2e Handle genvar variables in expressions.
In generate for blocks, there is a genvar that can be used in
expressions within the generate block. Generate this genvar in
the generated output, matched to the generate scope.

Stephen Williams 7fad717a1e Redesign selected_name rule to better handle complex prefixes
Prefixes of hierarchical names are complex and cannot be handled

Stephen Williams 621c09105c Sort the typedef emits so that types are emitted in the order used.
It is common for typedefs of complex types to use further typedefs.
Emit the type definitions depth first so that the types that are used
are defined first. This reduces the need for pre-declaration of types.

Stephen Williams 369a0b9eca VHDL named types work in more places. 2012-05-22 17:31:27 -07:00
Stephen Williams 4748f0cb5e Handle incomplete type declarations
Use these in the package library to allow for arbitrary mixing
of type declaration and use. This makes writing libraries much
easier.

Stephen Williams 039e6014fe Rework VType::emit_def methods / use packed arrays to implement arrays.
VHDL arrays are more like SV packed arrays, so use packed arrays
to implement them.

Stephen Williams 63b7fe059d Reword concat to handle aggregate arguments.
When concatenation expressions have aggregate arguments, we need to
get the type of the result down to the aggregate expressions so that
it can know how to interpret the elements.

Stephen Williams 67af96fee7 Module output ports use data_type_or_implicit
This cleans up the parsing of module output ports, allows for more
complex types on the ports, and fixes some bugs.

Stephen Williams 71d2401221 Handle VHDL records.
Elaborate records and emit them as packed SV records. Also handle
record members so handle name prefixes.

While we are at it, handle some cases of array aggregate expressions.

Stephen Williams 7eb89c5548 Parse name prefix syntax for record member reference.
When signals/variables are records, they are often referenced by
their members, using a prefix.name syntax. Parse that syntax and
generate "sorry" messages in elaboration.

Stephen Williams 0775e36a67 Properly elaborate argument types for binary relation expressions.
The argument types of binary relation expressions are decoupled
from the return type for the expression itself.

Cary R 9c99bce054 Update lex/yacc builds to be consistent and to support parallel builds
Not all the lex/yacc (flex/bison) targets were using a consistent syntax.
This patch fixes that and explicitly serializes the *.c/*.cc and *.h build.
Not doing this was causing problem when using make -j. The issue appears to
be that if two targets are specified for a rule (e.g. file.cc file.h: file.y)
make does not realize they are both built by the same call so the rule is
executed twice. Once for the .cc target and once for the .h target. This is
not a problem for a serial build. To work around this only use the .c/.cc
file in the main target and then make the .h file depend on the .c/.cc file
as a sub-target.

This patch fixes a mismatch in the delete style.

Cary R ed13de131d Use mkdir() instead of _mkdir() for MinGW
MinGW-w64 requires the use of mkdir() and MinGW-w32 appears to support
both so use mkdir() to allow compilation to work with both versions.

Cary R cc5efa45ba Fix two bugs and use the more efficient !empty() vs size() > 0
These two bugs were found with a recent cppcheck addition. It also
changes one occurrence of size() > 0 for the more efficient ! empty().

Cary R bcb963a235 Fix Cygwin compile problem (replace abs() call with ?:
This patch fixes a compile problem in Cygwin where there are two
definitions for abs() that do not match so the C++ code doesn't know
which one to call. To avoid the whole mess replace the call to abs()
with the appropriate ?: construct.

Martin Whitaker 58d182bdf3 Compiler fixes for MinGW.
In MinGW, when parameters are passed to vhdlpp by ivlpp, single quotes
are treated as ordinary characters. Use double quotes instead, as is
done in the driver.

Also, MinGW does not have a standard mkdir() function, so we need to
convert calls to mkdir() into calls to _mkdir().
