No there is no real way to do this from my experience (especially not at
compile time). I did have success with using an empty function after my flash
writer and then doing pointer arithmetic to find the size of the flash func, eg
void A()
{
...
}
void B()
{}
//find size of A
sizeofA = B - A; //something like that
I didn't feel safe doing this though so in the end I just ended up starting at
A and copying as much data as I could fit in my buffer because it doesn't
matter if you copy far too much, better to be safe than sorry.

Subject: [Mspgcc-users] Size of functions
Does msp430-gcc provide any systematic way, such as a generated symbol, from
which a C source file can determine the size of a function? I have a function
for field reprogramming, which is moved to RAM before use, and need to know
how many words to move.
