Hi Guys... I m in immediate need of the solution for writing a syntax analyser using lex and yacc....here the language i m using is C on Linux... (Red Hat...
Hi, Can any one please tell me what type of parser is used in most of the modern c/c++ compilers? I am actually interested in knowing as to what is the look...
I hope everyone had a good new year. I have been very busy over the last few months with travel and just had a moment to revisit my compiler project I was...

What I originally thought is I'd need to define my stack as something like: unsigned char stack[32768]; // 32k stack. Can someone comment on this concept and...

... Do you need to fetch objects off in larger chunks than a byte at a time? I.e. is an integer fetch something like I = stack[SP] << 24 | stack[SP+1] << 16 |...
Yes, I will need to be able to put 32-bit addresses, integers, longs, floats, etc on the stack. Can you provide me an example of how to push these types of...

... off the top of my head, not run through a compiler... // method 1: ignore alignment, do everything a byte at a time #define push(x) push(&x, sizeof(x)) ...
When you say that it does not work well with binary code, are you refering to an actual executable binary file or just storing the data in an intermediate file...

Graham, Again, thanks for all your help. I know we may have spoke about this in the past, but what about floats/doubles? These are 8-bytes. I extended your...

Hi there, I am new to this group, and I hope someone could help me, sorting out my question? I have had a look at Fabrice Bellard's otcc(n) Compiler. I am very...

Hello, I'm writing a lazy interpreter for a functional programming language. I've written my lexical analyzer in Lex, and parser in YACC. I want to generate...
Hi Haifa, Is this a class homework or just a personal project? ... Remember that in YACC, you've got three sections: the declaration, rules and user subroutine...
Hi Raheem, Thanks for the feedback and help. ... It's a personal project! Since what you're writing is an interpreter, ... Actually in order for it to be a...
Hi Haifa, ... Are you saying that what you really want to do is translate code in the language of your grammar into a program in lambda calculus, which is a...

Hiya Raheem (and everyone else) Firstly i can't thank u enough! You're really helping me put this all in perspective :) Ok lazy evaluation is basically...

Hi Group. I recently ported Jack's 'Tiny' compiler to C, and added some additional functionality (article published in January's C/C++ Users Journal). Anyway,...
