If it is possible, I would like to begin with a small project to get familiar with GCC code. I have been through the "Simple GCC projects" web page and I would be interested in project such as "Convert reorg.c to use the flow graph". Could someone help me to get involved ? I cannot but reinfo

Re: Newbie

Hi, I was (and largely still am) in your situation. I'd suggest to start, if you already haven't done so, by just trying building (bootstrapping) GCC as needed for development, running testsuite, learning how to compare two testsuite runs. Then try running cc1 under gdb, familiarize with the GCC o

Hello, I have a bunch of command line programs and I am trying to support Windows, Linux and an older version of Solaris. I got the same version of gcc working on all 3 platforms. Now the problem is that I can't get getopt_long to work which is provided by getopt.h. I don't know much about how al

Re: gcc newbie and open projects

Is this still an open project? and if so can anyone give me more information on what is needed? Yes, it is. Basically, insn-recog.c is a huge decision tree. genrecog.c builds it and outputs it as C code. It uses variables like "x0, x1, x2, ..., xn" which would become the virtual machine's

Hello all! I would very much like to contribute to the gcc project and as such have been monitoring the gcc list and perusing the documentation. One project in particular looks interesting. Make insn-recog.c use a byte-coded DFA. Richard Henderson and I started this back in 1999 but never fini

Hello All, I am trying to do some modifications to the register allocator and for the architecture I am dealing with, I want to handle different type of pseudos differently. All local scalars fall under one group, local struct/union variables under one group and all globals under one group. Given a
