Does .comm create a local or global variable?

__asm void DISABLE_INT( void )
{
    .comm DISABLE_VAR,4,4
    mfmsr   r3          ; Get current MSR
    rlwinm  r4,r3,0,17,15       ; Mask External Interrupt Enable bit
    mtmsr   r4          ;  in MSR (bit 16)
    sync                ; Must sync because of chip bug in some 603E.
    addis   r4,r0,DISABLE_VAR@ha
    stw r3,DISABLE_VAR@l(r4)    
}

Does the .comm statement in the __asm block create a local or global variable?

Depends on your assembler. Assuming GNU as the manual says global. You can use .lcomm for local.
