With the current kernel (2.6.23.1) in my R5000 based O2 it seems
impossible for GCC's exception unwinding machinery to unwind through
signal frames. The cause of the problems is the
ICACHE_REFILLS_WORKAROUND_WAR which puts the sigcontext at an almost
impossible to determine offset from the sig

Hello everybody,
I started working on the GCC CLI back end just a few weeks ago and I'm having
some trouble declaring new fields and adding them to an already existing
structure. I'm still fairly unfamiliar with gcc's code so please bear with me :)

I created a new branch for the debugging improvements based on
tracking multiple variables per computed value approach. The branch is
maintained by me and Michael Matz.
I'll do initial patch postings and checkins in the following days, please

Thanks,

Hi Uros,
It sounds like a great idea! I'm forwarding this to the Fortran list,
because I think it might raise quite some interest there also :

Hello everyone,
First, I'm a real beginner at gcc, so I hope my question is not so foolish.
I have used bounds checking patch and find it pretty good though it
can't deal with dangle pointer. The problem is my company doesn't use
GCC in it's every product.
It seems bounds checking mainly instrument
