[Qemu-devel] qemu-0.14.0 doesn't compile on ppc32

[Qemu-devel] qemu-0.14.0 doesn't compile on ppc32

[nello martuscielli]

hi,
i'm unable to compile qemu-0.14.0 on my PowerPC box.
The same kind of error there is also compiling qemu-0.13.0 in the same
environment.

Testing box is a PowerMac G4 with CRUX PPC (32bit) 2.7
gcc-4.5.2, binutils-2.21, glibc-2.12.2, linux-2.6.37.1
I always get the same compile failure.

instead with the same configure:
--audio-drv-list=alsa,sdl --enable-sdl --disable-bluez --disable-kvm
it compiles fine on my ppc64 (G5) box with CRUX PPC (64bit) 2.7

Can i receive help about? Is it really a compiler problem?
I compiled a lot of stuff and this is the first time i receive this
kind of error.

thanks  and my best regards,

It is most likely a compiler/setup issue. My guess your machine got out
of memory, and the OOM killer killed cc1. Try adding more memory and/or
swap, it should work.

Replacing -O2 with -O or no O at all will work too.

Some of qemu's code does seem to trigger rather excessive memory
use by gcc; for instance we've had problems with memory usage
building for ARM with gcc of target-sparc/translate.c wanting
gigabytes of RAM with some compiler flags:
https://bugs.launchpad.net/gcc-linaro/+bug/714921

I suspect it's all those large switch statements...

i've 1.5GB of ram and 1GB of swap.
I tried installing a chroot with the same CRUX PPC 32bit on my G5 and
there it compiles just fine as it does with the CRUX PPC 64bit. I
really don't know... maybe it's an hw failure on my G4.

It's on my todo list to report it to GCC, since this memory-hog behavior 
is a GCC regression.

compiling with  -fno-var-tracking i just succesfully built it without
any out of memory error.
So it seems it's possible to compile qemu on ppc32 without a
ridiculous high amount of ram with gcc-4.5.2.

We've been working on this in Linaro, and the following two patches
have been posted upstream:

    http://gcc.gnu.org/ml/gcc-patches/2011-03/msg00193.html
    http://gcc.gnu.org/ml/gcc-patches/2011-03/msg00255.html

so you can probably cross that item off your todo list :-)

Interesting.  Alexander Graf and I recently hit an out of memory when
building translate.o on ppc64 host.  It was solved by adding more RAM
to the box but this patch looks nice too ;).

Maybe the switch blocks should be rearranged, or inline attribute
removed from the functions. Are the nested switch and if statements
optimal from performance point of view or could there be a faster and
less memory hungry version?
