/*
* The SPARC stack frame is only held together by the frame pointers
* in the register windows. According to the SVR4 SPARC ABI
* Supplement, Low Level System Information/Operating System
* Interface/Software Trap Types, a type 3 trap will flush all of the
* register windows to the stack, which will make it possible to walk
* the frames and find the return addresses.
* However, it seems awfully expensive to incur a trap (system
* call) for every function call. It turns out that "call" simply puts
* the return address in %o7 expecting the "save" in the procedure to
* shift it into %i7; this means that before the "save" occurs, %o7
* contains the address of the call to mcount, and %i7 still contains
* the caller above that. The asm mcount here simply saves those
* registers in argument registers and branches to internal_mcount,
* simulating a call with arguments.
* Kludges:
* 1) the branch to internal_mcount is hard coded; it should be
* possible to tell asm to use the assembler-name of a symbol.
* 2) in theory, the function calling mcount could have saved %i7
* somewhere and reused the register; in practice, I *think* this will
* break longjmp (and maybe the debugger) but I'm not certain. (I take
* some comfort in the knowledge that it will break the native mcount
* as well.)
* 3) if builtin_return_address worked, this could be portable.
* However, it would really have to be optimized for arguments of 0
* and 1 and do something like what we have here in order to avoid the
* trap per function call performance hit.
* 4) the atexit and monsetup calls prevent this from simply
* being a leaf routine that doesn't do a "save" (and would thus have
* access to %o7 and %i7 directly) but the call to write() at the end
* would have also prevented this.
