I can't reproduce this with 4.4 or 4.5, either.

assembler error occurs when compiling this file with -O2 option. Without -O2
option the file was compiled without error.
Revision 152496 does not yet have this error. Revision of 152600 already has

On ARM, gcc generates assembly code for the bb-reorg.c test case that gas fails
to assemble. The pr34999.c test case fails for the same reason. The following
reduced assembly snippet illustrates it:
cat bb-reorg.s
--- Comment #4 from rguenth at gcc dot gnu dot org 2009-10-18 12:55 ---
We now print
t.i:3:1: sorry, unimplemented: gimple bytecode streams do not support the
optimization attribute
Thus fixed.

It looks like basic-block frequencies are completely off. The BB in question
is
# BLOCK 7 freq:3
# PRED: 6 [100.0%] (fallthru,exec) 7 [99.0%] (false,exec)
# ivtmp.65_38 = PHI ivtmp.65_113(6),
Take the following example:
void *memset(void *b, int c, unsigned long len)
{
unsigned long i;
for (i = 0; i len; i++)
((unsigned char *)b)[i] = c;
return b;
}
-O2 generates:
memset:
cmpwi 0,5,0
beqlr 0
mtctr 5
rlwinm
--- Comment #1 from rguenth at gcc dot gnu dot org 2009-10-18 13:53 ---
I think that's the usual loop-header copying trade-off. If you do it you
possibly increase code size, if you don't, you lose optimization - especially
on induction variables.

Linked from http://x264dev.multimedia.cx/?p=185, I'd forgotten all about the
ridiculous flamewar in this one.
Just as a note, the actual definitions of the four variables (from liba52):
x2k = x + 2 * k;
x3k =
I use this command line:
gcj -o ecj --main=org.eclipse.jdt.internal.compiler.batch.Main
/usr/local/share/java/ecj.jar
to compile ecj.jar into native binary ecj.
However, when I try running resulting binary on Hello World Java program it
crashes. Original ecj.jar compiles HelloWorld successfully.

pair(pair) is in the WP now.
4.5 gives no errors for the testcase, which I believe is correct; it's OK to
bind an rvalue to a const lvalue reference.

Should fail for cygwin as the target anyways. That is bug 41529.
Now it should compile for cygwin as the host though ...
