* netchild's mega-patch to isolate compiler dependencies into a centralJoerg Wunsch2005-03-021-13/+3
| | | | | | | | | | | | | | | | | | | place. This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

* Microoptimization to allow the compiler to evaluate ntohl() etc onPeter Wemm2003-09-221-4/+49
| | | | | | | | | | | | | | | known constants at compile time rather than at run time. We have a number of nasty hacks around the place to cache ntohl() of constants (eg: nfs). This change allows the compiler to compile-time evaluate ntohl(1) as 0x01000000 rather than having to emit assembler code to do it. This has other smaller flow-on effects because the compiler can see that ntohl(constant) itself has a constant value now and can propagate the compile time evaluation.

Submitted by: bde o Move a comment up in <machine/endian.h> that was accidentially moved down a few revisions ago. o Reenable userland's use of optimized inline-asm versions of byteorder(3) functions. o Fix ordering of prototypes vs. redefinition of byteorder(3) functions, so that the non-GCC (libc asm) case has proper prototypes. o Add proper prototypes for byteorder(3) functions in <sys/param.h>. o Prevent redundant duplicate prototypes by making use of the _BYTEORDER_PROTOTYPED define. o Move the bswap16(), bswap32(), bswap64() C functions into MD space for platforms in which asm versions don't exist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | device drivers for bus system with other endinesses than the CPU (using interfaces compatible to NetBSD): - bwap16() and bswap32(). These have optimized implementations on some architectures; for those that don't, there exist generic implementations. - macros to convert from a certain byte order to host byte order and vice versa, using a naming scheme like le16toh(), htole16(). These are implemented using the bswap functions. - stream bus space access functions, which do not perform a byte order conversion (while the normal access functions would if the bus endianess differs from the CPU endianess). htons(), htonl(), ntohs() and ntohl() are implemented using the new functions above for kernel usage. None of the above interfaces is currently exported to user land. Make use of the new functions in a few places where local implementations of the same functionality existed.

The previous fix was wrong and broke libpcap, which abuses -Dlint. Don't pollute the namespace if _POSIX_SOURCE is defined. This is broken - it makes almost everything in <machine/endian.h> inaccessible if _POSIX_SOURCE is defined, yet <machine/endian.h> is not a POSIX header. Other systems don't do it any better.
