go/src/runtime/string.c, branch fix-runtime-test-GOMAXPROCSFork of Go programming language with my patches.http://git.kilabit.info/go/atom?h=fix-runtime-test-GOMAXPROCS2014-11-11T22:07:06Z[dev.cc] runtime: convert basic library routines from C to Go2014-11-11T22:07:06ZRuss Coxrsc@golang.org2014-11-11T22:07:06Zurn:sha1:0c3c2c17243545e9bc7c5d158c5230fe299e8b73
float.c held bit patterns for special float64 values,
hiding from the real uses. Rewrite Go code not to
refer to those values directly.
Convert library routines in runtime.c and string.c.

liblink, runtime: diagnose and fix C code running on Go stack2014-09-08T18:05:23ZRuss Coxrsc@golang.org2014-09-08T18:05:23Zurn:sha1:c81a0ed3c50606d1ada0fd9b571611b3687c90e1
This CL contains compiler+runtime changes that detect C code
running on Go (not g0, not gsignal) stacks, and it contains
corrections for what it detected.
The detection works by changing the C prologue to use a different
stack guard word in the G than Go prologue does. On the g0 and
gsignal stacks, that stack guard word is set to the usual
stack guard value. But on ordinary Go stacks, that stack
guard word is set to ^0, which will make any stack split
check fail. The C prologue then calls morestackc instead
of morestack, and morestackc aborts the program with
a message about running C code on a Go stack.
This check catches all C code running on the Go stack
except NOSPLIT code. The NOSPLIT code is allowed,
so the check is complete. Since it is a dynamic check,
the code must execute to be caught. But unlike the static
checks we've been using in cmd/ld, the dynamic check
works with function pointers and other indirect calls.
For example it caught sigpanic being pushed onto Go
stacks in the signal handlers.
Fixes #8667.
