- 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.

+ 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.
