Hi Li,
this looks nice. Thanks for your work on this.

Thanks,

I've finished the first round of testing on all targets and will be
sending patches soon.
Overall, I think the results are quite satisfying.
For the current bunch of files, I get the same code on the following
targets:

Hi Li,
Hi.
I wrote to gcc mail list some time ago about my work on new RPC system.
So it has auto-parallelization for functions and uses GCC wrapper
compiler to do this job.
May be you will find it interesting in repect with your job.
Project site is - crpc.sf.net

I have these patches against 4.3.2/4.3.3 that should help with this.
(Sorry Eric, I've been too busy with the cygwin gcc distro releases to
start feeding these upstream yet, but they need to wait for 4.5 anyway.
They're not all in entirely suitable shape yet either.)
Hi,
I'd like to open the issue of minimum GMP/MPFR versions for gcc-4.5. We
currently require gmp-4.1 and mpfr-2.3.0 to build GCC.
Part of my motivation is that MPC requires more recent versions of these
packages. But also older GMP/MPFR have known bugs and I'd like to encourage
upgrading

That's good to know. As I said, I'm okay with your patch. I just wondered if
for 4.5 the cse_not_expected trick fixes it. In that case I'd have no problem
applying the patch to 4.4, but I would revert it after SSA

I must be missing something, as I don't see the connection to SSA expansion

problem in the past with mplayer) that some transformation

I agree that it seems like the first testcase should be ill-formed, but I can't
find anything in the standard that says it is, and the EDG front end also
accepts it. Do you have a citation?

GNU C and C++ compilers generate a one byte ahead source file name in the ELF

Block-scope ordinary identifiers with variably modified type are required
to have no linkage. Block-scope function declarations implicitly have
external linkage. However, GCC diagnoses such declarations with variably
modified type only with an explicit extern.
The code
int a;
void
f (void)
{
Compiling the test case, produces undefined symbols codestrs_4 and codestrs_8,
which will result in a link error.
If the static is dropped or one of the cases in the switch statement is
removed, the object file does not have undefined symbols.
Test case:
