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.

They're legally meaningless.

whitequark 15d2fbaf51 Add an inline hint on Generator::next(). 
This improves the generate benchmark by about 1ns.

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.

The exception to this is %eax is used not %edi on x86 because its

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.

edef 3397e0bcf1 at least allow different lifetimes in Context::swap2 
Really we should allow swapping between different stack types easily, so
we can easily swap between contexts with different stack types.

edef b986931817 remove copyright years 
They're obnoxious to update, and I'm told they have no legal value.

edef 709dad1c4a add Context::swap2, to allow distinct save/restore contexts 
Fix #5

Context::swap is now implemented in terms of Context::swap2, and it
might make sense to remove Context::swap entirely at some point.

edef cd4fe1ecc8 remove obsolete support for Rust stack limits 
rustc removed these in 7a3fdfbf674a08b7f6fd32c9124e52924a2f9a1c, and
this removes a Linux-specific TLS slot from our code.
