Once apon a time, gcc promised not to optimize away timing loops, but gcc started optimizing away the call to a null function in the timing loop here some time between gcc-3.3.3 and gcc-3.4.6, and it started optimizing away the timing loop itself some time between gcc-3.4.6 and gcc-4.2.

* 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

* Ha! This is a very interesting bug.Pawel Jakub Dawidek2005-08-081-4/+6
| | | | | | | | | | | | | | I copied strcasecmp() from userland to the kernel and it didn't worked! I started to debug the problem and I find out that this line: while (tolower(*us1) == tolower(*us2++)) { was adding _3_ bytes to 'us2' pointer. Am I loosing my minds here?!... No, in-kernel tolower() is a macro which uses its argument three times. Bad tolower(9), no cookie. Notes: svn path=/head/; revision=148865

| | | | | | | | | | | | We must not increase a capability of buffer size here, because codes which call these functions expect that dst and src are the same size.

* Refactor the CRC-32 code to enhance its usability. Move the actualMarcel Moolenaar2005-04-271-15/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | CRC logic to a new function: crc32_raw() that obtains the initial CRC value as well as leaves any post-processing to the caller. As such, it can be used when the initial CRC value is not ~0U or when the final CRC value does need to be inverted (bitwise). It also means that crc32_raw() can be called repeatedly when the data is not available as a single block, such as for scatter/gather lists and the likes. Avoid the additional call overhead incured by the refactoring by moving the implementation off crc32() to sys/systm.h and making it inlinable. Since crc32_raw() is itself trivial and since it may be used in loops that iterate over fragments, having it available for inlining can be beneficial. Hence, move its implementation to sys/systm.h as well. Keep the original implementation of crc32() in libkern/crc32.c for documentation purposes (as a comment of course).

| | | | | | | | | | | | implementations inspired by the ones in DragonFly. Unlike the DragonFly versions, these have a small data cache footprint, and my tests show that they're never slower than the old code except when the charset or the span is 0 or 1 characters.

* Move the kernel-specific logic to adjust frompc from MI to MD. ForMarcel Moolenaar2004-08-271-33/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | these two reasons: 1. On ia64 a function pointer does not hold the address of the first instruction of a functions implementation. It holds the address of a function descriptor. Hence the user(), btrap(), eintr() and bintr() prototypes are wrong for getting the actual code address. 2. The logic forces interrupt, trap and exception entry points to be layed-out contiguously. This can not be achieved on ia64 and is generally just bad programming. The MCOUNT_FROMPC_USER macro is used to set the frompc argument to some kernel address which represents any frompc that falls outside the kernel text range. The macro can expand to ~0U to bail out in that case. The MCOUNT_FROMPC_INTR macro is used to set the frompc argument to some kernel address to represent a call to a trap or interrupt handler. This to avoid that the trap or interrupt handler appear to be called from everywhere in the call graph. The macro can expand to ~0U to prevent adjusting frompc. Note that the argument is selfpc, not frompc. This commit defines the macros on all architectures equivalently to the original code in sys/libkern/mcount.c. People can take it from here...
