[AnyC-devel] CPP Support

[Patrick E. <pa...@pa...>]

I have finally added CPP support.  It took a bit longer than 
anticipated as I didn't understand that I would be getting some extra 
output from CPP and because I had to implement a C string parser.  
The parser should come in handy for string literals too.

I made the following changes to the version of the compiler in the 
CVS:

* Added cpp support
* Modified error/warning message format, added another error routine.
* Added preprocessor directive parsing support.
* Added missing newline to Generating Library output.
* Added C string parsing capabilities
* Made the file/line redirection messages from the preprocessor work.
* Fixed the duplicate memory_type problem.

It should also be noted that doing the parsing for the #pragma 
directives is trivial at this point.  All the routines are in place 
to handle it.  I'm quite pleased with the results.  Here's a sample 
from the new output:

[patearl@patmain anyc]$ ./anyc input.c output.asm
input.h:3: warning: Ignoring #pragma
input.c:4: warning: Ignoring #pragma
input.c:13: warning: Implicit type conversion
input.c:20: error: Assignment to invalid expression
input.c:21: error: invalid lvalue (assignment invalid)
input.c:33: warning: bitwise operator used on signed type
input.c:35: warning: Implicit type conversion
input.c:36: error: Can't mix signed and unsigned types without cast
input.c:36: warning: Implicit type conversion
input.c:38: warning: Implicit type conversion
Generating Library: 
.........................................................................................................................................................................
[patearl@patmain anyc]$ 

Notice the warning from the #included header file.  The 
multi-file/line error message support is shown here also.  A simple 
pragma parser can be placed in the section of the code that currently 
outputs that "Ignoring" message.

Have a nice day.
