Copy files from ../librthread in preparation for moving functionality

2017-08-15T06:13:24Z

from libpthread to libc. No changes to the build yet, just making it easier to review the substantive diffs. ok beck@ kettenis@ tedu@

Wrap fpgetround() so internal calls to it (seen on arm, powerpc, and sh)

2016-07-26T19:07:09Z

go direct instead of through the PLT. ok millert@ kettenis@

Consistently reference '_end' instead of 'end' in the brk/sbrk implementation

ok deraadt@

Only require 4 byte alignment on ILP32 archs

2016-05-29T07:59:36Z

Add XOR cookies for rp and sp. Switch from calling obsolete

2016-05-23T00:24:50Z

sig{block,setmask} to directly using the sigprocmask syscall. Remove longjmperror()-if-passed-real-sigcontext checks and the filling in of sigcontext fields that longjmp ignores. in snaps; ok deraadt@

Remove sigreturn declaration and the now-unused libc syscall stub

Use a Thread Information Block in both single and multi-threaded programs.

This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@

Don't add setjmp.S twice.

The asm in the MD_DISABLE_KBIND macro was too fragile and broke alpha and hppa.

2016-03-21T00:41:13Z

So instead, do the kbind disabling with syscall(). debugging and ok deraadt@, ok kettenis@

Rearrange C runtime bits: now that ld.so exports environ and __progname,

move their definitions and initialization in static links to libc.a Make crt0 always invoke a new func _csu_finish() in libc to process the auxv and to either register the ld.so cleanup function (in dynamic links) or initialize environ and __progname and do MC_DISABLE_KBIND (in static links). In libc, get pagesize from auxv; cache that between getpagesize() and sysconf(_SC_PAGESIZE) ok mpi@ "good time" deraadt@
