* BIG BIG commit: all left files merged from trunk [rev 22714]. Currenntly ↵Carmelo Amoroso2008-07-091-1/+1
| | | | NPTL sh4 port build and work fine. All committed to allow Khem Ray working on a working branch to integrate the ARM nptl port. MIPS nptl port not tested but should still building and working fine. There are some other part non yet merged with trunk (misc/internals and some headers file that need some more work).

* Use MAP_PRIVATE whenever __ARCH_HAS_MMU__ is set.Eric Andersen2004-07-151-1/+6

* Don't set errno if for zero SIZE returns.Miles Bader2003-10-161-11/+14
| | | | Code formatting cleanup.
* Fix errno values. Fix MALLOC_GLIBC_COMPAT handling in malloc/malloc.c,Eric Andersen2003-09-061-6/+18

| | | | | | | | | __UCLIBC_UCLINUX_BROKEN_MUNMAP__ (which is currently not defined anywhere). This makes other cases a tiny bit less efficient too. * Move the malloc lock into the heap structure (locking is still done at the malloc level though, not by the heap functions). * Initialize the malloc heap to contain a tiny initial static free-area so that programs that only do a very little allocation won't ever call mmap.
* Update debugging hooks.Miles Bader2002-09-061-0/+4

| | | | | | | | | 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.
* Misc small cleanups.Miles Bader2002-07-241-1/+2
|
* * Automatically try to unmap heap free-areas when they get very big.Miles Bader2002-07-231-60/+50
| | | | | | | | * 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.

* Miles Bader implemented a new mmap based malloc which is muchEric Andersen2002-07-181-867/+94
| | | | | | | 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!

* Fix up breakage resulting from flipping the sense of some defines. Change fromEric Andersen2001-03-191-9/+10
| | | | | | | | defining things to "0" in the disabled case to outright undefining them, lest code that does an "#ifdef FOO" get inadvertantly triggered. Remove now unneeded lines from Rules.mak which makes the command line smaller and avoids redundancy (since this stuff is now pulled in via features.h). -Erik
