whitequark aa364056fd Add more documentation, and rephrase it elsewhere. 2016-07-16 20:54:47 -04:00
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.

John Ericson 1ea4b01eda Use mostly the same registers for consistency
The exception to this is %eax is used not %edi on x86 because its
caller-save

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.

The two-parameter version is the only necessary API.

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.

edef 3f0ec83bf3 remove valgrind_stack_change

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