asm operand requires impossible reload

Hello!
I have the following #define:
#define HAL_DISABLE_INTERRUPTS(_old_) \
register int x ; \
asm volatile ("st r1, @-r15 ;\n" \
"mov ps, r1 ;\n" \
"ldi:8 #0x10, %0 ;\n" \
"and r1, %0 ;\n" \
"lsr #1, %0 ;\n" \
"ld @r15+, r1 ;\n" \
"andccr #0xef \n" \
: "=r" (x) \
); \
(_old_) = (x);
and then a c-File using this macro.
When I compile this c-File I get this error in the line, where the macro is
used:
asm operand requires impossible reload
What does this error message mean ?
If I compile using the -S switch, the generated assembler file looks fine and
the inline assembler is inserted right.
Thanks,
Lars
