If 3.4.4 works where 3.4.6 doesn't, you should report this as a
bug; either here, or to the GCC team (but please be aware that the
3.4 series isn't supported anymore), or to whoever built that
compiler for you.

Huh? 3.4 doesn't work for you, so that's why it should stay
a supported compiler?

I didn't bothered reporting it here because linux-mips website quotes
explicitly the dependency on 3.4.4. So at least, I imagined they are
aware of it. (And as you said, no point in reporting it to gcc...)

3.4.4 does. anyway, by this phrase, I only meant: "Dropping support
for 3.4 series won't help in this case"

that's fixed and I'm happiliy building the MIPS tree with gcc 3.3.3.
And I would be very unhappy to upgrade all my crosscompiler just because
someone thinks nobody build -rc kernel with older compilers. I do.

Crap can work. Given enough thrust pigs will fly, but it's not necessary a
good idea. [ RFC1925, 2.3 ]

I don't know what broken MIPS platform you've tried. I keep changing
between compiler versions all the time just so I can ensure builds with
older compilers keep working until we officially deciede to drop support
for them. So the minimum compiler version for 32-bit MIPS kernels is
gcc 3.2 and for 64-bit kernel gcc 3.3.
But for sake of sanity and productivity I definately don't mind dumping
support for gcc < 4.0 or maybe even 4.1. And while we're at it, let's
deprecate ancient binutils version as well. A minimum version of 2.17
would be nice as I could get rid of lads of .word sillyness which is
needed to support older binutils.
