|
|
|
|
|
|
|
|
|
|
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. */
