runtime: introduce a type for lfstacks

2017-03-19T22:42:24+00:00

The lfstack API is still a C-style API: lfstacks all have unhelpful
type uint64 and the APIs are package-level functions. Make the code
more readable and Go-style by creating an lfstack type with methods
for push, pop, and empty.

runtime: find a home for orphaned comments

2016-04-14T18:34:09+00:00

These comments were left behind after runtime.h was converted
from C to Go. I examined the original code and tried to move these
to the places that the most sense.

Revert "runtime: merge lfstack{Pack,Unpack} into one file"

2016-04-07T14:05:24+00:00

This broke solaris, which apparently does use the upper 17 bits of the address space.

This reverts commit 3b02c5b1b66df9cdb23d5a3243bb37b2c312ea1b.

runtime: merge lfstack{Pack,Unpack} into one file

2016-04-07T09:17:22+00:00

Merge the remaining lfstack{Pack,Unpack} implemetations into one file.

unsafe.Sizeof(uintptr(0)) == 4 is a constant comparison so this branch
folds away at compile time.

Dmitry confirmed that the upper 17 bits of an address will be zero for a
user mode pointer, so there is no need to sign extend on amd64 during
unpack, so we can reuse the same implementation as all othe 64 bit
archs.

runtime: remove unused return value from lfstackUnpack

2016-04-06T21:04:43+00:00

None of the two places that call lfstackUnpack use the second argument.
This simplifies a followup CL that merges the lfstack{Pack,Unpack}
implementations.

runtime: break atomics out into package runtime/internal/atomic

2015-11-10T17:38:04+00:00

This change breaks out most of the atomics functions in the runtime
into package runtime/internal/atomic. It adds some basic support
in the toolchain for runtime packages, and also modifies linux/arm
atomics to remove the dependency on the runtime's mutex. The mutexes
have been replaced with spinlocks.

all trybots are happy!
In addition to the trybots, I've tested on the darwin/arm64 builder,
on the darwin/arm builder, and on a ppc64le machine.

runtime: rename gothrow to throw

2014-12-28T06:16:16+00:00

Rename "gothrow" to "throw" now that the C version of "throw"
is no longer needed.

This change is purely mechanical except in panic.go where the
old version of "throw" has been deleted.

sed -i "" 's/[[:<:]]gothrow[[:>:]]/throw/g' runtime/*.go
