Jim,
I just wanted to see if this was on your radar for the 3.4 C runtime update. I
haven't been able to test it with beta3 because I hit some earlier roadblocks.
Thanks,

Ah it is probably because the backtrack and memorize option. I strongly
advise that you don't use these but left factor your grammar. However, I
will fix it of course.
Jim

I believe that it is caused by using the memorize=true; option and
building 64-bit. The following grammar has these warnings in the
generated TestParser.c (compiled as C++ code in Visual Studio 2008).
You will find the offending line at the beginning of the generated
prog() function.
-----------------------------
grammar Test;
options
{
language=C;
backtrack=true;
memoize=true;
}
prog
: SOMETHING+;
SOMETHING
: 'A'..'Z';

Thanks,
Justin

There were some such warnings a number of versions back but they are
all fixed as far as I know. What construct are you using that results
in the warning? If you give me a reproducible grammar snippet, then I
will fix it for the next release, which is just waiting on my other
commitments right now.

Jim,
I am working on making our compiler support 64-bit builds, and have
run
into a number of compiler warnings due to conflicting types in the
ANTLR generated C code:
warning C4244: '=' : conversion from 'ANTLR3_MARKER' to
'ANTLR3_UINT32', possible loss of data
This comes from the line:
axisMask_StartIndex = INDEX();
axisMask_StartIndex is declared as type ANTLR3_UINT32, and INDEX() is
returning type ANTLR3_MARKER. On a 64-bit build (on a Windows
machine),
ANTLR3_UINT32 is a typedef of uint32_t, and ANTLR3_MARKER is of type
ANTLR3_INT64 which is a typedef of int64_t. It seems to me that this
is
a bug in the template, and that axisMask_StartIndex should have been
declared as type ANTLR3_MARKER.
My questions are, do you know of a quick workaround for this for now?
Do you know if this will be fixed in the next release of the C target
runtime? Also, is there a tenative release date for the C runtime
that
will officially support ANTLR 3.3 (it seems that the code generated
by
ANTLR 3.3 works ok with the 3.2 C runtime)?
Thanks,
Justin Murray
