* Implement extensions on top of standards instead of the other way around.Ed Schouten2012-01-032-14/+2
| | | | | | | | Now that index() and rindex() have become unused, simply turn them into wrappers around strchr() and strrchr(), respectively. Notes: svn path=/head/; revision=229366
* Use strchr() and strrchr().Ed Schouten2012-01-021-2/+2
| | | | | | | | | | | It seems strchr() and strrchr() are used more often than index() and rindex(). Therefore, simply migrate all kernel code to use it. For the XFS code, remove an empty line to make the code identical to the code in the Linux kernel. Notes: svn path=/head/; revision=229272
* Remove the now unused skpc() function.Ed Schouten2012-01-011-49/+0
| | | | | | | | | | | | It was only used by ufs and ext2 and I have really strong doubts that there are other pieces of code that also use this function. If it turns out that external drivers use this code as well, I'd be happy to migrate or revert. Bump __FreeBSD_version while there. Notes: svn path=/head/; revision=229204
* Introducing memcchr(3).Ed Schouten2012-01-011-0/+115
| | | | | | | | | | | | | | | | | | | | | | | | It seems two of the file system drivers we have in the tree, namely ufs and ext3, use a function called `skpc()'. The meaning of this function does not seem to be documented in FreeBSD, but it turns out one needs to be a VAX programmer to understand what it does. SPKC is an instruction on the VAX that does the opposite of memchr(). It searches for the non-equal character. Add a new function called memcchr() to the tree that has the following advantages over skpc(): - It has a name that makes more sense than skpc(). Just like strcspn() matches the complement of strspn(), memcchr() is the complement of memchr(). - It is faster than skpc(). Similar to our strlen() in libc, it compares entire words, instead of single bytes. It seems that for this routine this yields a sixfold performance increase on amd64. - It has a man page.

* Add memmove() to the kernel, making the kernel compile with Clang.Ed Schouten2009-02-281-0/+38
| | | | | | | | | | | | | | | When copying big structures, LLVM generates calls to memmove(), because it may not be able to figure out whether structures overlap. This caused linker errors to occur. memmove() is now implemented using bcopy(). Ideally it would be the other way around, but that can be solved in the future. On ARM we don't do add anything, because it already has memmove(). Discussed on: arch@ Reviewed by: rdivacky Notes: svn path=/head/; revision=189170

* This commit fixes the issue with alias_sctp.c. NoRandall Stewart2009-02-141-0/+643
| | | | | | | | | | | | | | | | | longer do we require SCTP to be in the kernel for the lib to be able to handle SCTP. We do this by moving the CRC32c checksum into libkern/crc32.c and then adjusting all routines to use the common methods. Note that this will improve the performance of iSCSI since they were using the old single 256 bit table lookup versus the slicing 8 algorithm (which gives a 4x speed up in CRC32c calculation :-D) Reviewed by:rwatson, gnn, scottl, paolo MFC after: 4 week?

* The kernel implemented 'memcmp' is an alias for 'bcmp'. However, memcmpDavid E. O'Brien2008-09-231-0/+53
| | | | | | | | | | | | | | and bcmp are not the same thing. 'man bcmp' states that the return is "non-zero" if the two byte strings are not identical. Where as, 'man memcmp' states that the return is the "difference between the first two differing bytes (treated as unsigned char values" if the two byte strings are not identical. So provide a proper memcmp(9), but it is a C implementation not a tuned assembly implementation. Therefore bcmp(9) should be preferred over memcmp(9). Notes: svn path=/head/; revision=183299

* Normalize a significant number of kernel malloc type names:Robert Watson2005-10-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | - Prefer '_' to ' ', as it results in more easily parsed results in memory monitoring tools such as vmstat. - Remove punctuation that is incompatible with using memory type names as file names, such as '/' characters. - Disambiguate some collisions by adding subsystem prefixes to some memory types. - Generally prefer lower case to upper case. - If the same type is defined in multiple architecture directories, attempt to use the same name in additional cases. Not all instances were caught in this change, so more work is required to finish this conversion. Similar changes are required for UMA zone names. Notes: svn path=/head/; revision=151897
