See https://github.com/pabigot/freertos-mspgcc for FreeRTOS using MSPGCC as
of mid 2012. The use of naked is in Source/portable/GCC/MSP430, but does
not apply to the timer ISR itself. It was not necessary to use external
assembly sources.

Even though I think it is sorted now, I still wonder (for my own knowledge and
completeness) if there is a way to either override just one of the vector
positions (or is there a magic name that given to the function accomplishes the
same thing) or is there a way to override all of the vector
Yes, the interrupt attribute causes the function to be named __isr_X where
X is the word offset of the interrupt from the vector table start (viz.,
the value of the attribute's parameter divided by two). Those symbols are
used to initialize the vector table in crt0ivtbl.o.
Thus, if you're using
Hello,
I am trying to port FreeRTOS to the MSP430F5519.
In order to write the context switching part, I need to write a timer
interrupt service routine in pure assembly (the compiler right now is doing
some extra push before I can do anything in the ISR, even with nothing in
the body...)
How
Hi Wayne,
have You tried __attribute__ ((naked)) ? This makes function without any
push/pop... just return. Inside body use asm ( ... );

Yes I've tried it, however on an interrupt function it seems to only do half
the job!
Found something that works, putting a single branch in the ISR to a naked
function. At least it seems to work for now, who knows when the compiler will
decide to insert a push before my branch and break it
