Hi,
today I have encountered an unpleasant problem with the function
get_ref_base_and_extent() when it claimed a known and constant offset
for the expression insn_4(D)->u.fld[arg.82_3].rt_rtvec. (arg being a
default_def parameter of the function, insn is an rtx). Moreover, it

I do know these problems and also the place that I have to fix.
I guess a meta bug like this one "Wrong code with -O3
-fgraphite-identity on polyhedron benchmarks" is enough.
Thanks for testing,

I have done a few tests at r142680 on i686-apple-darwin9 on the polyhedron
test suite and I have found a couple of wrong codes at -O3 -fgraphite-identity,
namely for capacita.f90 and fatigue.f90 (nothing to report so far for
channel.f90
and induct.f90). I have little time to explore the problems.

Hi,
I made an extension of the alpha backend. To make it cleaner I have
created another backend directory (in gcc/config/mtalpha). I updated the
configure scripts and binutils accordingly (with the new path, name
"mtalpha", features of my extension).
The problem is when I generate the compil

Gents,
thanks for taking the time to explain stuff - hopefully, in the end,
we'll resolve this.

Firstly, issues with my choice of configure options might be
important - but they are not relevant to the underlying problem.
The basic problem is entirely repeatable with default options

Not just that: SIN is a pure (or const, depending on -frounding-math)
function, which can be subject to CSE and DCE. I don't see anything
suggesting that for MATMUL in

Hello,
I have a basic-block and I want to get the last jump insn of it.
I use BB_END (bb) for that purpose.
The instruction I get is a NOTE_INSN_PROLOGUE_END which appears right
before the jump insn; and when doing NEXT_INSN for that note I get
the first insn of the next bb (code_label); which me
