DragonFly-2.3.1.379.geb9f47 master lib/libc/amd64 DEFS.h SYS.h l
commit eb9f4715e9826cbe89be0778e43ed144bcd1d5bc
Author: Peter Avalos <pavalos@dragonflybsd.org>
Date: Sun Apr 26 03:57:31 2009 +0000
Update some of the amd64 parts of libc:
* Change the syscall stub branch orders so that the static branch
prediction will assume that syscalls will succeed rather than fail.
* Add error handling for PSEUDO syscalls.
* Add END() macros for Assembler code. This causes the symbol
table to include the size of the function.
* ldexp: Fix a typo in the !__GNUC__ case and remove an obsolete
comment.
* setjmp/longjmp changes:
-Save and restore the control part of the MXCSR in addition to the
i387 control word to ensure that the two are consistent.
-Don't clobber the FPU exception flags in longjmp. C99 requires them
to remain unchanged.
