| | | | | | | | the function bodies require only 2 to 10 instructions. However, it leads to application binaries that refer to a private ABI, namely, the softfloat innards in libc. This could complicate future changes in the implementation of the floating-point emulation layer, so it seems best to have programs refer to the official fe* entry points in libm.

* Merge index() and strchr() together.ed2012-01-031-4/+3
| | | | | | | | | | | | | | | | | As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead. Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications. Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr(). This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.

* Mark uname(), getdomainname() and setdomainname() with COMPAT_FREEBSD4.ed2008-11-091-2/+1
| | | | | | | | | | | | | | | | | | | | | Looking at our source code history, it seems the uname(), getdomainname() and setdomainname() system calls got deprecated somewhere after FreeBSD 1.1, but they have never been phased out properly. Because we don't have a COMPAT_FREEBSD1, just use COMPAT_FREEBSD4. Also fix the Linuxolator to build without the setdomainname() routine by just making it call userland_sysctl on kern.domainname. Also replace the setdomainname()'s implementation to use this approach, because we're duplicating code with sysctl_domainname(). I wasn't able to keep these three routines working in our COMPAT_FREEBSD32, because that would require yet another keyword for syscalls.master (COMPAT4+NOPROTO). Because this routine is probably unused already, this won't be a problem in practice. If it turns out to be a problem, we'll just restore this functionality. Reviewed by: rdivacky, kib

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
