I'm getting the following compilation error when trying to build the DFU bootloader example, using gcc 4.9.3 (4_9-2015q3) on Mac.

"mov r12, %1\n\t" \
"svc %0\n\t" \
"bx r14\n\t" \
: /* no output */ \

: "r12" /* do we need to clobber? */ \
); \
} \
_Pragma("GCC diagnostic pop")
I guess this has something to do with the use of var args within a macro, but I don't know what exactly.
