[MLton-devel] cvs commit: stack profiling

[Stephen Weeks]

>   I'll try out self compiles tomorrow and see what happens.

Here are the times for the "Compile SML" portion of a self compile
(with the usual flags), running 5 different versions of the compiler.

time	compiler compiled with
------	-------------------------------
591s	-profile no
636s	-profile alloc -profile-stack false
916s	-profile alloc -profile-stack true
614s	-profile time -profile-stack false
711s	-profile time -profile-stack true

So, the hit for time stack profiling is only 20%, which is pretty
good, considering stack walking didn't even finish.  And the hit for
allocation stack profiling is only 55%, which is also pretty good.
