[Qemu-devel] compile error with gcc 3.4.1

[Qemu-devel] compile error with gcc 3.4.1

[Iain McFarlane]

Hi,

When trying to compile from cvs i get the following error:

gcc -Wall -O2 -g -fno-strict-aliasing -fomit-frame-pointer 
-mpreferred-stack-boundary=2 -falign-functions=0 -fno-reorder-blocks 
-fno-optimize-sibling-calls -I. -I/home/iain/qemu/qemu/target-i386 
-I/home/iain/qemu/qemu -D_GNU_SOURCE -I/home/iain/qemu/qemu/slirp -c -o 
op.o /home/iain/qemu/qemu/target-i386/op.c
/home/iain/qemu/qemu/target-i386/ops_template_mem.h: In function 
`op_rolb_kernel_T0_T1_cc':
/home/iain/qemu/qemu/softmmu_header.h:179: error: can't find a register in 
class `GENERAL_REGS' while reloading `asm'
make[1]: *** [op.o] Error 1
make[1]: Leaving directory `/home/iain/src/qemu/i386-softmmu'

if I reduce it to -O1 then there is no error and everything works ok.

Thanks,

Iain

There is an opened bug that looks very similar:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15482

gcc 3.4.1 is still not out, it has just been frozen yesterday.
Did you try with another version of gcc?

A version of 3.4.1 has been in mandrake cooker for at least a week now - 
they've been updating the package from cvs

It used to work absolutely fine with 3.4.0 so I presume something in gcc has 
changed - there is a lot of comment about the new version in the cooker 
mailing lists.  It is no big deal as I can still compile with -O1 but I think 
it will become more of an issue as people upgrade to gcc-3.4.1

Cheers

Iain

This reminds me of the 2.96 version that never existed...
Some showstoppers bugs were corrected for the forthcoming
*official* 3.4.1 release, so if MDK did not update their
build, using it looks dangerous to me.

You are not using 3.4.1, just a snapshot of it, so you
can't extrapolate ;-)

I have not been ever able to compile qemu by gcc3.4.0 -- haven't you make
mistake by using 3.3.x?
