amd64 build fails within ESXi guest
I'm trying to build HEAD within an ESXi guest system, and the build errors while building the boot code. I've attached the tail end of the log. The host is a Dell Vostro 230 with CPU: Intel(R) Core(TM)2 Quad CPUQ8400 @ 2.66GHz (2659.61-MHz K8-class CPU) and the guest is allocated 256MB of RAM.

This is ESXi 4.1.0.
Locally we've been building the amd64 kernel with a few different
flags and ran into this in our kernel build.
Try this definition of do_cpuid instead:
static __inline void
do_cpuid(u_int ax, u_int *p)
{
#if 0
/*
* Isilon: get a compile error on a new hwpmc file:
/data/sb/BR_HAB_BSDMERGE_STABLE7/src/sys/modules/hwpmc/../../dev/hwpmc/hwpmc_core.c:
In function 'pmc_core_initialize':
./machine/cpufunc.h:111: error: can't find a register in class 'BREG'
while reloading 'asm'
./machine/cpufunc.h:111: error: 'asm' operand has impossible constraints
This presumably has to do with -fPIC. See
http://sam.zoy.org/blog/2007-04-13-shlib-with-non-pic-code-have-inline-assembly-and-pic-mix-well
for this workaround.
*/
__asm __volatile(cpuid
: =a (p[0]), =b (p[1]), =c (p[2]), =d (p[3])
: 0 (ax));
#else
__asm __volatile(push %%ebx \n\t /* save %ebx */
cpuid\n\t
movl %%ebx, %1 \n\t /* save what cpuid just put in
%ebx */
pop %%ebx\n\t /* restore the old %ebx */
: =a (p[0]), =m (p[1]), =c (p[2]), =d (p[3])
: a(ax)
: cc);
#endif
}
Note that using =r for the constraint on p[1] isn't sufficient as once
in a while the compiler has chosen %ebx, which then leads to garbage
in the register after the pop.
Thanks,
