Hi,
I'm running the gentoo version of gcc-3.4.5 on my ppc system here. The
patch below is required to make qemu compile cleanly for me. The
compiler gives me some very unintuitive error message from within an
__asm__ statement but the fix is rather trivial.
The patch fixes line 746 of linux-user/elfload.c:
if (k_platform)
NEW_AUX_ENT(AT_PLATFORM, (target_ulong) u_platform);
In the original definition NEW_AUX_ENT expanded to several statements
of which only the first will be dependant on the if statement above. I
guess the patch changes the code to the way it was actually intended.
