If you define WITHOUT_SYSCALL_COMPAT, the .c wrappers will go away and libc will make direct syscalls. After 7-stable starts, the direct syscall method will be default. Approved by: re (kensmith)
* Adjust the syscall stub macros to be consistent in their meaning. Inpeter2007-07-041-14/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | particular: SYSCALL() makes a syscall, with errno handling, and continues execution directly after the macro in the non-error case. RSYSCALL() is just like SYSCALL(), but returns after success. Both SYSCALL(name) and RSYSCALL(name) export "__sys_name" as a strong symbol, with "_name" and "name" as weak aliases. PSEUDO() is just like RSYSCALL(), but skipping the "name" weak alias. It still does "__sys_name" and "_name". Change i386 to add errno handling to PSEUDO. The same for amd64 and sparc64, with appear to have copied the behavior. ia64 was correct (as was alpha). Just remove some apparently unused variants of the macros. (untested!) I believe powerpc is correct. Fix arm to not export "name" from the PSEUDO case. Remove apparently extra unused variants. (untested!) The errno problem manifested on i386/amd64/sparc64 by having "PSEUDO" classified syscalls return without setting errno. eg: "addr = mmap()" could return with "addr" = 22 instead of setting errno to 22 and returning -1.

* Some libc symbol map cleanups.deischen2007-05-311-4/+0
| | | | | | | | | | | | | | | | | | | | | net: endhostdnsent is named _endhostdnsent and is private to netdb family of functions. posix1e: acl_size.c has been never compiled in, so there's no "acl_size". rpc: "getnetid" is a static function. stdtime: "gtime" is #ifdef'ed out in the source. some symbols are specific only to some architectures, e.g., ___tls_get_addr is only defined on i386. __htonl, __htons, __ntohl and __ntohs are no longer functions, they are now (internal) defines in <machine/endian.h>.

This makes it possible to say `mantissa & ~LDBL_NBIT' in places that previously used an #ifdef to select the right expression. The optimizer should dispense with the extra arithmetic when LDBL_NBIT is 0.

| | | | | | | | | | | | | | | | scalbn() implementation from libm. (The two functions are defined to be identical, but ldexp() lives in libc for backwards compatibility.) The old ldexp() implementation... - was more complicated than this one - set errno instead of raising FP exceptions - got some corner cases wrong (e.g. ldexp(1.0, 2000) in round-to-zero mode) The new implementation lives in libc/gen instead of libc/$MACHINE_ARCH/gen, since we don't need N copies of a machine-independent file. The amd64 and i386 platforms retain their fast and correct MD implementations and override this one.

| | | | | | | | | | | | | | | | | | | | | isnormal() the hard way, rather than relying on fpclassify(). This is a lose in the sense that we need a total of 12 functions, but it is necessary for binary compatibility because we have never bumped libm's major version number. In particular, isinf(), isnan(), and isnanf() were BSD libc functions before they were C99 macros, so we can't reimplement them in terms of fpclassify() without adding a dependency on libc.so.5. I have tried to arrange things so that programs that could be compiled in FreeBSD 4.X will generate the same external references when compiled in 5.X. At the same time, the new macros should remain C99-compliant. The isinf() and isnan() functions remain in libc for historical reasons; however, I have moved the functions that implement the macros isfinite() and isnormal() to libm where they belong. Moreover, half a dozen MD versions of isinf() and isnan() have been replaced with MI versions that work equally well. Prodded by: kris
