- * 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.
