Hi,
I was trying to make a symbol table for all the variable declarations

Hi,
As part of GSoC 2010, I am developing a front end for GIMPLE.
You can find the basic theme of the project at:
http://gcc.gnu.org/wiki/GimpleFrontEnd
One of the most important components in this GIMPLE Front End is to
convert the GIMPLE tuples into text.
How such a textual representation shoul

Hi,
I am working to knw the details of the tree-ssa pass.I had this small
piece of code as my test case:
void func()
{
int x=10;
int a=5;
if(a==x)
{
x=x+1;
}
else
{
x=x-1;
}
a=x;
}
and when i did a

I got the following output :

int a;

Hi,
I posted this question on the mailing list gcc-h...@gcc.gnu.org
but did not get any reply about it.
I have bootstrapped gcc 4.4.2 on my machine and now i have to make
changes in gcc code. However, I dont know how to make those changes
effective.Do I need to change the source files accor

Hi,
I have been trying to understand the gcc source code and am interested
in customizing gcc to support speculative parallelization of
conditional branching and loop instructions instructions.I am
considering gimple as input.
I want to know what is the entry point to the gimplification pass? and

I have been told that openMP does parallelizing of loops, but these
types of optimizations are generally don
