/* Function prologues on the Motorola MCore processors consist of:
|
1999-08-09 23:36:23 +02:00
|
|
|
|
|
|
|
|
|
- adjustments to the stack pointer (r1 used as scratch register)
|
|
|
|
|
- store word/multiples that use r0 as the base address
|
|
|
|
|
- making a copy of r0 into another register (a "frame" pointer)
|
|
|
|
|
|
|
|
|
|
Note that the MCore really doesn't have a real frame pointer.
|
|
|
|
|
Instead, the compiler may copy the SP into a register (usually
|
|
|
|
|
r8) to act as an arg pointer. For our target-dependent purposes,
|
|
|
|
|
the frame info's "frame" member will be the beginning of the
|
|
|
|
|
frame. The SP could, in fact, point below this.
|
|
|
|
|
|
|
|
|
|
The prologue ends when an instruction fails to meet either of
|
|
|
|
|
the first two criteria or when an FP is made. We make a special
|
|
|
|
|
exception for gcc. When compiling unoptimized code, gcc will
|
|
|
|
|
setup stack slots. We need to make sure that we skip the filling
|
|
|
|
|
of these stack slots as much as possible. This is only done
|
|
|
|
|
when SKIP_PROLOGUE is set, so that it does not mess up
|
|
|
|
|
backtraces. */
