* Redo the locking, so that it may actually work. Now locking is done atMiles Bader2002-07-258-130/+186
| | | | | | | | | the malloc/free level, not within the heap abstraction, and there's a separate lock to control sbrk access. Also, get rid of the separate `unmap_free_area' function in free.c, and just put the code in the `free' function directly, which saves a bunch of space (even compared to using an inline function) for some reason.
* Factor out some common code sequences into inline functions.Miles Bader2002-07-242-53/+74

* * Automatically try to unmap heap free-areas when they get very big.Miles Bader2002-07-238-190/+234
| | | | | | | | * Instead of using mmap/munmap directly for large allocations, just use the heap for everything (this is reasonable now that heap memory can be unmapped). * Use sbrk instead of mmap/munmap on systems with an MMU.
* Doc fix.Miles Bader2002-07-195-5/+5

* Rename mutex stuff to use heap-specific names.Miles Bader2002-07-195-24/+26

* Miles Bader implemented a new mmap based malloc which is muchEric Andersen2002-07-1816-1392/+740
| | | | | | | smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles!

* New locale support (in development). Supports LC_CTYPE, LC_NUMERIC,Manuel Novoa III2002-05-062-14/+172
| | | | | | | | | | | | | | | | | | | | | | LC_TIME, LC_MONETARY, and LC_MESSAGES for the SUSv3 items. Also, nl_langinfo() when real locale support is enabled. New implementation of ctype.h. New implementation of wctype.h. New implementation of most of the string functions (smaller). New implementation of the wcs/wmem functions. These are untested, but they're also just preprocessor-modified versions ot the corresponding str/mem functions. Tweaked qsort and new bsearch. Stuff still pending: stdlib.h and wchar.h mb<->wc functions. I actually have working versions of the stdlib ones, but the reentrant versions from wchar.h require some reworking. Basic replacement and translit support for wc->mb conversions. (groundwork laid). Simple-minded collate support such as was provided by the previous locale implementation. (mostly done -- 8-bit codesets only) Shared mmaping of the locale data and strerror message text.
* Remove function declartions from include/features.h, createEric Andersen2002-04-013-0/+3

* Add implementations of strtof() and strtold(). These are a bitEric Andersen2002-03-143-1/+65
| | | | | | lame, since internally I'm just using strtod, but that keeps things small, and has the side effect of making these easy to write. -Erik
