Hi Dylan, looks ok now. One thing: the ISR is now: __vector_21: ; @__vector_21 __vector_21$local: sei push r0 push r1 in r0, 63 push r0 clr r0 push r24 lds r24, v1 sts v2, r24 pop r24 pop r0 out 63, r0 pop r1 pop r0 reti There are unneccessary push/pops of r1 and r0 too, since the clr is useless ... GCC had the same problem but they made improvements. Thanks. Am 31.03.20 um 08:09 schrieb Wilhelm Meier via llvm-dev: > Hi Dylan, > > thank you. I'll be back with a test ... > > Wilhelm > &g...

...or_21v>: 74: 80 91 60 00 lds r24, 0x0060 ; 0x800060 <__data_end> 78: 80 93 61 00 sts 0x0061, r24 ; 0x800061 <v2> 7c: 08 95 ret So, in C++ mode it is not recognized as ISR due to name mangling. Furthermore there are no register push/pos and no reti. Whats wrong? Thanks.

...rrupt handler as an ordinary function on > x86-32-linux. There can be significant differences between an interrupt handler and a void f(void) function. An interrupt handler may have to: - Save /all/ registers, including those that are normally caller saved. - Use a special return instruction (RETI). - Step over the "red zone" on the stack. - Set up a safe stack frame before calling normal functions. I usually write the first level interrupt handler in assembler, and then call normal C function from there.
