* Synch with trunk at rev 22997.Carmelo Amoroso2008-07-311-1/+1
| | | | | | | Basically trailing whitespaces removal, fix non standard keywords asm -> __asm__ inline -> __inline__ and some minor changes on trunk. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* 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).

| | | | | | | | | 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.

* * Automatically try to unmap heap free-areas when they get very big.Miles Bader2002-07-231-1/+5
| | | | | | | | * 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.
* Rename mutex stuff to use heap-specific names.Miles Bader2002-07-191-3/+3

* Miles Bader implemented a new mmap based malloc which is muchEric Andersen2002-07-181-0/+127
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!
