Just wanted to let you know that as of the 20040924 snapshot of GCC
4.0, QEMU won't compile. It fails when compiling op.c:

gcc -Wall -O2 -g -fno-strict-aliasing -fomit-frame-pointer -mpreferred-stack-
boundary=2 -falign-functions=0 -fno-gcse -fno-reorder-blocks -fno-optimize-sibl
ing-calls -I. -Iqemu-snapshot-2004-10-10_23/target-i386
-Iqemu-snapshot-2004-10-10_23 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64
 -D_LARGEFILE_SOURCE -Iqemu-snapshot-2004-10-10_23/slirp -c -
o op.o qemu-snapshot-2004-10-10_23/target-i386/op.c

qemu-snapshot-2004-10-10_23/target-i386/ops_template_mem.h: In
function 'op_cmpxchgb_kernel_T0_T1_EAX_cc':
qemu-snapshot-2004-10-10_23/softmmu_header.h:183: error: can't find a
register in class 'GENERAL_REGS' while reloading 'asm'

So I guess the -fno-gcse hack won't help us anymore.


Cheers,
A.
