does extending the test in target-i386/op.c to cover gcc 3.4.0 solve this?
now it only handles gcc 3.3.X.

#if !(__GNUC__ == 3 && __GNUC_MINOR__ == 3)
#define ASM_SOFTMMU

[Qemu-devel] qemu CVS HEAD does not compile with gcc 3.4

Here's what happens:

It's the function "glue", which is static inline, but still uses ebp.  Huh?
We are compiling -fomit-frame-pointer...?

The function spills eax, ecx and edx, takes two register arguments and two
memory location arguments.  Apparently, gcc 3.4 wants to put the memory
locations into registers as well...?
