/* Return the innermost lexical block in execution
in a specified stack frame. The frame address is assumed valid.
If ADDR_IN_BLOCK is non-zero, set *ADDR_IN_BLOCK to the exact code
address we used to choose the block. We use this to find a source
line, to decide which macro definitions are in scope.
The value returned in *ADDR_IN_BLOCK isn't necessarily the frame's
PC, and may not really be a valid PC at all. For example, in the
caller of a function declared to never return, the code at the
return address will never be reached, so the call instruction may
be the very last instruction in the block. So the address we use
to choose the block is actually one byte before the return address
--- hopefully pointing us at the call instruction, or its delay
slot instruction. */
