This is a back port from development of the code to put and check
that the vvp input file is the right version. It also adds the -V
flag to vvp. It does not add the VERSION_TAG information so will
only produce the single string ivl_version tag. The runtime will
read both forms since if it is feed a V0.9 file we want it to
complain nicely (no syntax error). To change the displayed version
for the various programs and checks change version.h.
This configure option causes the installed commands to have
a suffix string that makes them distinct from other versions
that also have a suffix string. This allows for multiple
installed versions of Icarus Verilog.
Also, move installed C/C++ header files into a subdirectory of
their own under the target include directory, to make clearer
the purpose and source of those files.
(cherry picked from commit 4bc90f7cfd)
The file and line number information needs to be copied when
doing a macro expansion. This prevents a macro that expands to
an `ifdef of other construct that needs to push the stack
from core dumping because the file is NULL.
This is a direct back port from the development branch. It adds
the `elsif directive and adds check that the conditional
directives are used correctly.
For text macro substitutions the lexor did not allow leading underscores.
This patch fixes that omission. All other places that text macros may be
used appear to be correct.
C style comments were not recognized as comments in false or
suppressed sections of ifdef/etc. blocks. This prohibited an
unneeded endif/else/etc. from being commented out with this
style of comment.
