The GNU Compiler Collection version 4.4.2 has been released.
GCC 4.4.2 is a bug-fix release containing fixes for regressions and
serious bugs in GCC 4.4.1. This release is available from the
FTP servers listed at:
http://www.gnu.org/order/ftp.html
Please do not contact me directly regarding

the MVS libraries and header are installed.

Hi there. The architecture I'm working on porting gcc to has indirect
addressing but no constant offset or register offset versions. Code

p[2] = 0;
p[3] = 0;
Turns into:

This is a deliberate design decision.
If you really need to refer to classes with dlsym, use -fno-indirect-classes.
However, this has a number of restrictions: in particular it fixes the ABI

CRTP does not seem to work together with variadic templates.
On a larger program, type canonization seems to be faulty and leads to a g++
crash.

struct base a, ENCLOSING

GNU gold (GNU Binutils for Debian 2.20) 1.9
This happens only if I use all of -flto -O1 -use-linker-plugin, not using -O1,
or not using -use-linker-plugin hides the bug (and not using -flto too of
course).

Confirmed, for -m32 -march=i686 -O3 -g vs. -g0 generates different code on:
typedef struct { int t; } *T;
struct S1 { unsigned s1; };
struct S2 { struct S1 s2; };
struct S3 { unsigned s3; struct S2 **s4; };
struct S5

The line numbers in the traceback in comment #9 are completly bogus. I had to
upgrade my gdb to version 0.7. Now it looks much better:
Core was generated by `ia64-unknown-linux-gnu-ld --verbose

I confirm this on FreeBSD-8.0 for gcc-4.5.0.20091001.
I notified the maintainer of FreeBSD gcc port.
But once the fix will be found it should go into gcj itself, not into port.

verified that compiling only bfd/elf64-ia64.c with -fno-ipa-sra is sufficient
to get a working ia64-unknown-linux-gnu-ld.

You can't merge no-exception and exception code, it seems. Should exceptions
be enabled per-function for LTO?

Actually, it is not DSE1 but already loop-invariant.c, and the difference is in
max_reg_pressure of the current loop (4 vs. 5 for one of the classes).

How to run testsuite for gcj?
When I run 'gmake check-gcc' from the build directory it doesn't run gcj tests
at all, and gcc/g++ tests summaries are all empty. Not sure what that means.
