c5a82dd848 * New MI man page for fp{set,get}{round,sticky,mask}(3). 
* Implement fpgetsticky() for alpha.
* Direct fpsetsticky() and fp{get,set}mask() into alpha kernel via sysarch(2).
* Define new sysarch(2) stub for above and install and distribute sysarch.h
for alpha.  (The fpcr IS user mode r/w, but for reasons beyond the scope
of a commit message kernel calls are needed.) And much kernel Magick is
required before these do anything, but this way programs compiled under
1.4 will DTRT on future snapshots and releases.

5423093850 Modify syncicache on PowerPC from an inline to a real function. 
Support different cache line sizes with the same object code in userland.
While here, move the function to implementation name space.

713a1d89ff Add _dtoul() which gcc generates a lot. Maybe it should go in another file. 1999-04-04 21:01:39 +00:00

dccf2a15e4 While in transition, conditionally rename _ASM_LABEL(cerror) and 
_ASM_LABEL(curbrk) to _C_LABEL(__cerror) and _C_LABEL(__curbrk), respectively,
depending on the object format chosen, to avoid user namespace clashes.

e387e174fc Amend for the PLT fixes, things broke last night with the changes to SYS.h 
and cerror.S. In particular, the syscalls in the files committed below were
broken.

cb41675175 Add PIC_PROLOGUE before the PLT call to cerror. ELF dynamic linking needs 
this.

2d40554ce3 _setjmp.S needs OFFSETOF_SC_{FP,}REGS, so include <machine/signal.h> 
even tho _setjmp()/_longjmp() don't manipulate signals.  (more thought?)

f44e783c10 When invoking ALTENTRY, the arguments may not contain spaces (not even 
after the ",") or this will fail when cpp is run with -traditional-cpp.

dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

6348b7d5b5 * On architectures using ELF, and conditionally on those in transition, rename 
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

efd37a7da8 Warn about references to the compatibility vfork() (i.e. the vfork() with 
the 4.4BSD non-shared-address-space semantics), and direct the user to
include <unistd.h> to generate the correct reference.

This warning isn't about an ABI compatibility issue, but the new vfork() is
considerably faster.
