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.
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.
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.
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 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.
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().
Entity generics are easily implemented as module parameters, so make
it so. Give the parameters their default values from the generic declaration.
Array bounds may use values that cannot be evaluated right away, so
put off their evaluation.
This patch makes the code consistently use struct/class in the C++ files,
it removes a couple shadow warnings and where a class pointer is passed to
the C routines, it defines the pointer as a class for C++ and as struct for
C and it removes a namespace std duplication.
