altos/arm: Align data so that gcc 5.4 doesn't do byte-accesses. Add -Wcast-align

2017-01-25T19:21:43+00:00

Gcc 5.4.1 tracks alignment of data through assignments, so that a uint32_t pointer which comes from byte-aligned uint8_t data: extern uint8_t foo[]; uint32_t *q = (void *) foo; Fetches and stores through this pointer are done bytewise. This is slow (meh), but if q references a device register, things to bad very quickly. This patch works around this bug in the compiler by adding __attribute__((aligned(4))) tags to some variables, or changing them from uint8_t to uint32_t. Places doing this will now be caught as I've added -Wcast-align to the compiler flags. That required adding (void *) casts, after the relevant code was checked to make sure the compiler could tell that the addresses were aligned. Signed-off-by: Keith Packard

altos/stm: Make ao_usb_set_address static. Saves a bunch of text space

2016-12-13T07:18:50+00:00

I'm sure this makes the function end up in-lined, which saves enough text space to fit the flash loader in ROM again. Signed-off-by: Keith Packard
