Hi!
As mentioned in the PR, for boolean x we currently optimize
in phiopt x ? 0 : -1 into -(int)!x but it can be optimized as
(int) x - 1 which is one less operation both in GIMPLE and in x86 assembly.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
And/or, shall we have a m
Hi Segher,
I've been holding off pinging these knowing you had a lot of other
review work, but maybe that's settling down now? You already OK'd

[PATCH 4/8] [RS6000]
Hi!
The following patch improves code generation on the included testcase by
enabling two_value_replacement on booleans. It does that only for arg0/arg1
values that conditional_replacement doesn't handle, and only does it if not
in the early phiopt pass, because conditional_replacement isn't done

Thank you for your review. I have applied all the changes now, as posted
in their most recent versions, except for 01/31 where I have noticed an
anomaly in the included gcc/testsuite/gcc.c-torture/compile/pr5890

Now that VAX has been converted as well, the entry can be updated here as well.

Hi Joseph,
the patch to drop qualifiers during lvalue conversion
was broken, because the code to emit atomic loads did
not trigger anymore. I now added a test that scans for
"atomic_load".
I should have taken the new warning for
_Atomic int y;
y; // warning statement with no effect

Andreas Schwab has created a bug entry for this issue,
using awk or shell should be fine to get the same functionality, but
it might take some time,
so I plan to add some checking to detect python, python2 or python3,
and skip this step if none of
We'll try to canonicalize the arch string for --with-arch,

GCC require python to build for RISC-V port, it's not expect as
the GCC requirement.
So this patch is made this as optional, detect python and only use it
