whitequark 145c18125a Explain how trampolines work. 2016-08-13 13:38:04 +02:00
whitequark b79e7c0a9b Rename Stack::top() to Stack::base(), which is correct.
Fixes #25.
2016-08-13 13:38:04 +02:00
whitequark 7d5075edc2 Add more examples to README.
This also renames some functions for a mild increase in backtrace
clarity.

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 ddbf9a5afe Reimplement Generator to pass both input and output values around. 2016-08-13 13:38:04 +02:00
whitequark 308df32ac2 Use a more semantically correct PhantomData field in Generator. 2016-08-13 13:38:04 +02:00
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.

whitequark a5d3430e63 Make Generator safe in presence of destructors. 2016-08-13 13:38:04 +02:00
whitequark 23cf17865d Remove workaround for rust-lang/rust#25544. 2016-08-13 13:38:04 +02:00
edef ca43ba0498 Make fringe::Context private. 2016-08-13 13:38:04 +02:00
edef b1a6b17d0a Move the Context tests and benches into src/
This concludes preparations for making Context private again.
2016-08-13 13:38:04 +02:00
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 40fbfdde0c Kill impl StackPointer.
That was a silly idea for a silly abstraction, and it brought no
improvement, only confusion. So, revert it.

whitequark ebd9ca8dec Allocate guard page under existing stack, not in it.
This fixes a segfault when the allocated stack is just one page long.

This also refactors the fringe::os module to use Result consistently.

edef bc184237cc rename simd -> context_simd
This fixes a spurious rustc warning.
2016-07-16 16:18:58 -04:00
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.
