mycroft 9e21b6555a In the `MY THAT'S GROSS' department...
Eliminate the recursive include of machine/endian.h from sys/endian.h.

mycroft 02905321b2 Foolish consistency. Mainly, always use underscores and sys/endian.h. 2000-03-16 15:09:34 +00:00
simonb 3c185af5fd Include <sys/endian.h> after defining whether where are little- or
big-endian.  i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions.  mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.

bouyer 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.

kleink 1b6a24c1d4 Support for compound statements enclosed in parenthes to appear as
expressions is a GNU C extension; mark as such them with __extension__ to
suppress portability warnings.  Addresses kern/3562 and misc/6185, as suggested
by Dave Sainty <dave@dtsp.co.nz>.

thorpej 1484fa567d Generate dependencies on the CPU type options (I386_CPU, I486_CPU, ...) 1998-01-15 19:47:36 +00:00
bouyer 6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

thorpej 8d85b14ca8 Give the __GNUC__ versions of ntohl() and friends the proper (in_addr_t
or in_port_t) signature.

christos 1f54d4ded6 add in_addr_t and in_port_t and use them. 1996-10-11 00:02:47 +00:00
jtc 0edf3579f4 Revert last change.
Changing types from unsigned {long,short} to u_int{32,16}_t causes problems
in a lot of userlevel code because those types aren't defined when machine/
endian.h is included.  And IMO including sys/types.h in machine/endian.h
is clearly wrong.

XPG4.2 defines new types in_addr_t and in_port_t for the {h,n}to{n,h}{l,s}
functions.  But we don't have time to figure out the implementation issues
given the current release schedule.
1996-05-08 20:00:38 +00:00
christos 391a4ddc7c use u_int32_t instead of unsigned long
and u_int16_t instead of short in the {h,n}to{n,h}{l,s} inline routines
and macros.

mycroft 551f7bc780 Since we're no longer using xchg instructions, there's no reason to prefer
a q reg over and other.  Also, fix some types in the case of _POSIX_SOURCE.
1994-07-15 21:10:21 +00:00
jtc 91906bc019 Inline assembly [hn]to[nh][sl] functions used xchgb %h1,%b1 instead of the
faster (on the i486 & i586) rorw $8, %w1.  The inline assembly for GCC 1.X
already used rorw.  Using rorw is one byte longer, but we wouldn't be
inlining at all if we weren't optimizing for speed.

cgd efa03b9a6c fix from Thomas Eberhardt <thomas@mathematik.uni-Bremen.de>:
byte swap macros used a variable "X" internally, which would get
screwed up if user programs #defined "X".  change uses of X to __x.
