edef 4813dd7411 Leak the stack if it's unsafe to drop it 
We can't free the stack before the generator has returned, or been
unwound. Without unwinding, the only safe course of action is to leak
it.

whitequark f34ddc6805 Don't use core::intrinsics. 
The core::intrinsics::unreachable() we used at the end of every naked
function is essentially pointless, as #[naked] implies that intrinsic
at the end of the function. rustc currently does not implement that
behavior (rust-lang/rust#32487), but it is a bug. On top of that,
anything except a single asm!() in naked functions is likely to be
disallowed in the future (rust-lang/rust#32490).

A nice side effect is that we avoid the core_intrinsics feature,
which will be never stabilized, though neither asm nor
naked_functions are likely to be stabilized soon.

whitequark 302ceef10a Clarify the Windows situation. 
Also, remove the Windows OsStack implementation. It will not ever
be useful in libfringe, as even if we add support for Windows
using fibers, the OS allocates stacks for fibers and we needn't
do it manually.

This concludes preparations for making Context private again.

whitequark 892a7696ec Allow unwinding to propagate across a context swap. 
The main purpose of this is having nice backtraces in gdb, although
it also slightly simplifies poisoning state of the API consumers
after a panic.

whitequark cbe136b762 Completely rework fringe::Context and fringe::arch. 
The new design concerns itself with one thing and exactly one thing:
passing values back and forth with an extern "C" function.
This allows to simplify fringe::arch into a single primitive, swap.

edef ff25697444 remove StackSource 
Nothing in this library took StackSources, and it's probably too
high-level a concept to include here. Maybe later.

edef cbfb62e62f only expose context and stack through the facade 
It's fairly pointless to have submodules when there are only three
items.

edef 2760a0a7aa move Valgrind handling into Context 
fix #3
This takes all Valgrind functionality private again.
Valgrind stack registrations are now associated with a Context, not with
a Stack. This makes sense, since it's only actually a stack when a
Context is running on it. Perhaps Valgrind will even be able to detect
early stack frees now.
 2015-04-16 02:59:58 -04:00
edef 7e0b126f42 separate all the libc interaction out per OS 
We're now handling more of this ourselves, and leaving less to libstd.
Hopefully, we'll eventually break free of libstd, leaving a
highly-focused low-level library that retains all its conveniences in
freestanding environments.
 2015-04-16 02:16:08 -04:00
edef db6a2ff89b factor Valgrind support out and expose it 
Now other Stack / StackSource implementations can use the same Valgrind
code. Ref #3.

edef 31652d7b8f 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.
