Hi,
We are implementing a new context-sensitive algorithm for pointer
analysis in GCC-4.5.0.
Can anyone please suggest some good benchmarks for testing it ?
Thanks,
Swaroop.

framework for writing GCC instrumentation plug-ins called InterAspect.
I am releasing the project today, and since there is a general

Hi,
I am doing a port in GCC 4.5.1. For the port
1. there is only (reg + offset) addressing mode only when reg is SP.
Other base registers are not allowed
2. FP cannot be used as a base register. (FP based addressing is done
by copying it into a base register)
In order to take advantage of FP el
Thanks for the explanation, Robert.
To be clear, it's code maintained by Adacore that has run afoul of the
change. I don't believe gprbuild is part of Adacore's public
repository, so I'm not quite sure how I'm supposed to obtain a version
of gprbuild that will compile with GCC 4.6.0. This v

Emitting a bunch of CLOBBERs in epilogue/sibcall_epilogue works also, at least
for the small example above. But using LOCAL_REGNO seems more natural to me and

True. It's a pretty elegant solution, and I missed it in my mail (I

Hi all,
I am trying to use define_split, but it seems to me that I don't
understand how it is used.
It says in the gccint.pdf (which I use as my tutorial (is there
anything better or more up to date?)) that the combiner only uses the
define_split if it doesn't find any define_insn to match. This i
