Hi Amit,
Thanks for the additional insight. I'm not using the -mlongcall compiler
switch but nonetheless have experieinced CC2.7.2 compiler crashes,
particularly in some of the schema source.
I was able to eliminate some of the compiler crashes by "simplifying" (e.g.
splitting a compound C++ statement containing many operations into multiple
simple C++ statements) the Xerces code fragments that were crashing the
compiler.
Some of the "simplifying" necessary in the schema code proved too laborious
and I resorted to the
#include <assert.h>
#ifdef VXWORKS
assert(false);
#else
XERCES CODE THAT IS CRASHING YOUR COMPILER
#endif
technique since my application doesn't require schema.

Hello Dennis,
Thanks for the reply. I tried doing that, but only one person answered and
that didnt help much; nothing from the GNU people themselves.
But I discovered the problem late friday evening. And this might be helpful
to others too.
Our build file was using the flag "-mlongcall" alongwith all the other flags
given to ccppc. That was throwing the "unrecognizable insn" error. Though I
dont exactly know what is meant by "unrecognizable insn", I do know this
has got something to do with jumping between instructions. I just took it
off and it compiled with just some warnings.
I hope atleast some people gain from my experience .. I had already tried 4
versions of Xerces (v1.7, v1.4, v1.3 and v1.2) !!
Thanks,
~Amit

Hi Shah,
Perhaps you could try reposting this to a GNU CC users forum.

Hello,
Irrespective of whatever version of Xerces I use, when I try to compile, I
always see the following in the DTD directory. I gather that some people
have used the ccppc compiler before. Has anyone see this earlier? What is
meant by unrecognizable insn? It seems like this is a compiler issue. Can
someone shed some light?
Thanks,
~amit
