2015-04-15 22:48:42 -04:00

add valgrind_stack_change
...
Unlike valgrind_stack_register, this won't automatically swap
if `start > end`. It's probably wiser to pretend it doesn't swap at all.

factor Valgrind support out and expose it

Now other Stack / StackSource implementations can use the same Valgrind
code. Ref #3 .

use a statically-allocated stack for Context::new benchmarking
...
Now it's an actual context creation benchmark, instead of benchmarking
our stack creation, which is swappable anyway.

limit compilation of arch to x86_64
...
the current code only supports x86_64 (#1 ), and we want to fail hard on
any other architecture for now.

move arch::{initialize_call_frame, swap} to inherent mthods of Registers
...
they're now Registers::{new, swap}, because they're
already effectively a constructor and a method.

complete rewrite!
...
featuring 7ns inlineable context switches, no more separately-built
assembly objects, and a vastly nicer interface.
incontext/outcontext are no more, context switch calls now take a single
context structure, which functions as both.
everything now also functions without any heap allocations -- for the
context setup, only an FnOnce() value is necessary.
