Hi all,

are there missing optimizer bug fixes in gcc-3.3.3 targeted at arm=20
as in the 3.0_BETA branch? (I note that gcc-3 is up to gcc-3.4.3 (I think))=
...

Long story:

The NetBSD-3.0_BETA compiler is:

> marie is 118% gcc -v
> Configured with: /home/nick/work/netbsd/src/tools/gcc/../../gnu/dist/gcc/
> configure --enable-long-long --disable-multilib --enable-threads=20
> --disable-symvers --build=3Di386-unknown-netbsdelf2.0. --host=3Darm--netb=
sdelf
> --target=3Darm--netbsdelf
> Thread model: posix
> gcc version 3.3.3 (NetBSD nb3 20040520)

With the NetBSD-3.0_BETA lex built with this gcc with optimization, I can't
build the sourceforge:adtools cross-gcc-3.4.3 (host NetBSD/arm 3.0_BETA,
target amigaos-ppc).

Somewhere shortly after starting gmake after configuring the cross-compiler,
I get:


> flex  -ogengtype-lex.c ../../gcc/gcc/gengtype-lex.l

Now, looking at the lex file, and the input.h file, there is no way I can
detect this can happen. OTOH, if I compile flex without optimization,
compilation of the cross-compiler succeeds.

Compilation also succeeds (with optimization) on Solaris/sparc 2.8
with some gcc-3ish compiler, and NetBSD/i386 3.0_BETA, to name the
two I tried.

Sorry, I don't have any less bulky test case (yet?).
