[Mspgcc-users] what happened to __get_frame_address?

[Alex S. <al...@gm...>]

Hi all!

I am trying to make a switch to mspgcc4 but I get an `undefined
reference to `__get_frame_address' ' error from the linker (in gcc 3..
the macro I am using, GET_FRAME_ADDR_F( __FUNCTION__ ), expands to
assembly code so it does work). This should be a built-in, it seems
and the extern declaration in iomacros.h may be screwing it up. Is
there a fix for this(other functions of similar kind, like
__bic_sr_irq, work fine)?

The error is the same when I use the latest git version of mspgcc4.

Finally, unrelated to this, the code that mspgcc4 generates is about
1K longer than the 3.2.3 branch. Is there a trick (I know this
question is too general but I am looking for something obvious I may
have overlooked) other than -Os switch to make it generate smaller
code?
