| | | | | | include/sgidefs.h wasn't getting scrubbed. Fix it so this symlink gets properly scrubbed, even for mipsel. -Erik
* The __set_errno macro _must_ match that defined in include/bits/errno.h. WeEric Andersen2002-07-261-1/+9
| | | | | | | can't tack in the return -1 since then when people include errno.h, the return -1 mysteriously vanishes... Setting the __set_errno back and restoring the 'return -1;' calls to each _syscall[0-n] macro makes mips syscalls work again. -Erik

* 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.

* * 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.

* 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!

| | | | | | | | | | | ...inet_pton breaks since tolower is implemented as a macro and its argument is evaluated more than once: while ((ch = tolower (*src++)) != '\0') { So I fixed it by just undefining tolower() so we use the function version, not the macro. -Erik
