[Qemu-devel] Compile failure of 0.7.2 with gcc 4.0.1

[Qemu-devel] Compile failure of 0.7.2 with gcc 4.0.1

[Richard Neill]

Dear All,

I thought you might like to know the following:

  Neither Qemu 0.7.2 nor 0.7.1 will compile under gcc 4.0.1, which is 
the default under Mandrake 2006. It works fine with the older 3.3.6 though.

Here are the relevant bits of the output. I've cut all the irrelvant 
bits, but I'm including the warnings in case they are useful. However, 
the important bit is near the end. (I've separated the paragraph for 
clarity.) The actual error is this:

     /home/cvsp2/qemu-test/qemu-0.7.2/target-i386/ops_sse.h:574:
     error: unable to find a register to spill in class 'GENERAL_REGS'


Hope that's useful.

Best wishes,

Richard

This is a know problem, and there's little that can be done right now
without considerable work.
