Extended Description
After some experimenting with cross compilation to the ARM, I'm seeing this compiler error:
Invalid operand for inline asm constraint 'I'!
I suspect this is the offending macro:
#define __with_interrupts_disabled(expr)
do {
u_int cpsr_save, tmp;
__asm __volatile(
"mrs %0, cpsr;"
"orr %1, %0, %2;"
"msr cpsr_all, %1;"
: "=r" (cpsr_save), "=r" (tmp)
: "I" (I32_bit | F32_bit)
: "cc" );
(expr);
__asm __volatile(
"msr cpsr_all, %0"
: /* no output */
: "r" (cpsr_save)
: "cc" );
} while(0)
