SUB / Function Lock - britlion - 03-17-2010
I think we need some word in the definition for subs and functions that makes -O2/3 NOT optimize something out of the loop because it doesn't seem to be called - but needs to be kept in, perhaps because it contains asm code that we need to keep.
REQUIRED SUB Name()
REQUIRED FUNCTION a(b as uInteger) as uinteger
or some such?
This then culminates in interesting stuff like
REQUIRED SUB initialize () AS INTERRUPT
<code>
END SUB
Re: SUB / Function Lock - boriel - 03-17-2010
I was also thinking a different approach: Tell the compiler which SUBs, FUNCs and vars it requires:
Code:
DIM Var1, Var2 AS uByte : REM Required vars
SUB mysub
ASM
[...]
END ASM
END SUB
ASM
[...]
END ASM (mysub, Var1, Var2) : REM Tells what this block requiresBoth solutions (yours and mine) are OK. So I think I can implement when the next release is out.
