Hi. Sorry for inconvenience. The link should work now. If it wont, then please have patience for few days. The work of server upgradation is going on, which might have coused problem. We are talking to system administrator for the same. The problem will be fixed within a couple of days. - Seema

ts to foo would be stored. Is there any way to find it out? - Seema Ravandale Note: I am working on GCC-4.3.0

Re: How to use gcc source and try new optmization techniques

Hi Rohan, I have already worked on cfg data structure, plugin "data flow pass" on cfg. For this purpose, following links would be useful. http://www.cse.iitb.ac.in/~uday/gcc-workshop/?file=downloads more info can be available at http://www.cse.iitb.ac.in/grc/ - Seema On Thu, Aug 2

Re: mf-runtime.c IC error..

allocation so that there will be fewer calls to ggc_realloc, "Make" went through. Is there any known/similar problem related to ggc_realloc() ?? Is it to do with book-keeping information getting merged with allocated memory or it is taken care by gcc-garbage collector?? Thank you. - Seema

What is purpose of numbered variables??

operations. Is this only purpose in case of globals?? e.g int b; //local variable array[b] = c will be translated to b.0 = b; array[b.0] = c anything to do with SSA? What if we disable them? -Seema Ravandale

Access to symbol table??

Hi... This is Seema here. I am working on GCC in IITB as research fellow. Actually i am trying to find out scope information of a variable. But i didnt find any information within "decl" data structure of a variable. somewhere i read that "level # attribute" gives the inforamt
