Bad wording isn't the only problem :-(. That is why there is an
ia32 psABI discussion group. You can bring up any ia32 psABI
issue

That perked up my curiosity:

In rtlanal.c we have these lines:
nregs_ymode = hard_regno_nregs[xregno][ymode];
...
&& (GET_MODE_SIZE (ymode) % nregs_ymode) == 0)
The m32c cc1 crashes here because xregno is 1 and ymode is QI, and
register 1 cannot hold a QI value (there are no QImode ops that take
that register), so
Hi all,
Looks like gcc 4.3 has some rather inconvenient changes in C++ FE, with the
latest trunk. Lets see with an example :
[~]> cat test.cpp
#define foo bar
#define foo baz
[~]> g++ -c test.cpp
test.cpp:2:1: error: "foo" redefined
test.cpp:1:1: error: this is the location of the previous defi

Hello all.
As many know, various linux distributors are working on re-compiling
their distros with GCC mainline in the hopes of helping GCC 4.3
stabilize. As part of this effort, many bugs have been filed in GCC
bugzilla, and many portability issues have been identified.

Hi, All. I don't know How to regenerate a new
configure file while added new target on config.sub,
and gcc/config.gcc. I am a newcomer in using GCC.
Thank you very much.

Not surprising since it is a pedwarn. It would be nice to point to the
relevant sections of the standard in the code as a comment, if you
