Re: [Simulavr-devel] __builtin_avr_delay_cycles and avr-gcc 4.5.3 issue

[Michael Hennebry]

Neither the original nor the proposed code works as advertised.
ms is supposed to be tenths of milliseconds, so I renamed it.

// Delay in 1/10's of a millisecond
// won't work with -O0, use -O1 for debugging
void msleep(INT16U ms10) { for( ; ms10; --ms10) _delay_ms(0.1); } }



-O0 really is pretty awful for debugging.
There is so much object code that it's hard to wade through.
In one example, "fred+=greg;" made four copies of fred's address.
