2002-09-04(free):Miles Bader
Update debug statement. Update to use __heap_delete and __heap_is_empty.
2002-09-04(__heap_delete): Renamed from `__heap_unlink_free_area'.Miles Bader
(__heap_free_area_alloc): Use __heap_delete. (__heap_is_empty): New macro.
2002-08-30Doc fix.Miles Bader
2002-08-30(__heap_free): Tighten up the inner loop, and make the code more readable.Miles Bader
2002-08-30Use `likely' & `unlikely' instead of the `__malloc_'-prefixed versions.Miles Bader
2002-08-30(likely, unlikely): New macros.Miles Bader
2002-08-30(likely, unlikely): New macros.Miles Bader
(__malloc_likely, __malloc_unlikely): Macros removed.
2002-08-25Kill the HAS_LONG_LONG option. It really did not make a lot ofEric Andersen
sense to exclude it, gcc always supports long long, and we never fully excluded long long anyways (off64_t for example). -Erik
2002-08-19Eliminate wrapping of struct stat and use the kernel versionEric Andersen
directly. Eliminate all the attendant baggage. Fix internal types to match kernel types more closely. -Erik
2002-08-19(CSRC): Make contents source files, not object files.Miles Bader
2002-08-19(CSRC): Add `memalign.c'.Miles Bader
2002-08-19Initial checkin.Miles Bader
2002-08-19(realloc): Follow new arg conventions of MALLOC_SET_SIZE.Miles Bader
2002-08-19(malloc): Use MALLOC_SETUP.Miles Bader
2002-08-19(MALLOC_SETUP): New macro.Miles Bader
(MALLOC_SET_SIZE): Take the base-address of the block, not the user-address. (MALLOC_ADDR): Macro removed.
2002-08-15Patch from Jarkko to fix drand48 to not use long long whenEric Andersen
long long support is disabled in the uClibc Config.
2002-08-14Use __malloc_unlikely instead of `likely'.Miles Bader
2002-08-14Add flow-control hints with __malloc_likely and __malloc_unlikely.Miles Bader
2002-08-14(__malloc_likely, __malloc_unlikely): New macros.Miles Bader
2002-08-14Handle zero NEW_SIZE case.Miles Bader
2002-08-13Use `return' for null pointers, to avoid a giant block holding the restMiles Bader
of the function.
2002-08-12Doh! missed a spot.Eric Andersen
-Erik
2002-08-12Revert commit by davidm to printf.c that initialized conv_numManuel Novoa III
needlessly. To do so increases the generated code size with bcc. Eliminate duplicate define warnings in wstring.c. Fix potentially broken preprocessor comparisons. The preprocessor converts integers to maximal signed type, so inequality comparisons involving UINTMAX_MAX, ULLONG_MAX, and (if no long long) ULONG_MAX were potentially broken.
2002-08-12Geez I'm an idiot some times. I shouldn't code when I'm exhausted.Eric Andersen
I _totally_ screwed up the locking on exit and atexit such that it didn't do any good at all. -Erik
2002-08-09Add missing thread-safe locking.Eric Andersen
-Erik
2002-08-08Fix lockingEric Andersen
2002-08-08Cleanup some silly warningsEric Andersen
2002-08-07Changed my mind. Keep this separate.Eric Andersen
-Erik
2002-08-07Rewrite getenvEric Andersen
2002-08-07Per suggestion from Miles Bader, move calloc.c to libc/stdlib.Eric Andersen
Also, Manuel notices that I forgot to check for when nmemb=0, which would result in a segfault, so fix that case as well. -Erik
2002-08-06Unify calloc (its the same thing regardless of the underlyingEric Andersen
malloc implementation). Fix problem reported to bugtraq about problems with integer overflow that can occur during the computation of the memory region size by calloc (and similar functions) which could result in a subsequent buffer overflow. -Erik
2002-08-01Use MALLOC_REALLOC_MIN_FREE_SIZE.Miles Bader
2002-08-01(MALLOC_REALLOC_MIN_FREE_SIZE): New macro.Miles Bader
Enable debugging if MALLOC_DEBUGGING is defined.
2002-08-01(HEAP_MIN_SIZE): New macro.Miles Bader
(HEAP_MIN_FREE_AREA_SIZE): Increase size. Enable debugging if HEAP_DEBUGGING is defined.
2002-07-31In the allocate-and-copy case, don't include the malloc header in ourMiles Bader
size calculations.
2002-07-31Update debugging printfs.Miles Bader
2002-07-31Per discussion on the mailing list, simply vfork -> fork mapping to only applyEric Andersen
iff we do not have vfork available, which is simpler and more reasonable. -Erik
2002-07-31Account for MALLOC_HEADER_SIZE when calculating new size.Miles Bader
2002-07-31Use MALLOC_HEADER_SIZE.Miles Bader
2002-07-31(MALLOC_HEADER_SIZE): New macro.Miles Bader
(MALLOC_BASE, MALLOC_ADDR): Use it.
2002-07-30Make sure NEW_SIZE is a multiple of HEAP_GRANULARITY.Miles Bader
Calculate amount freed when shrinking correctly.
2002-07-30Update the size of grown/shrunk allocations.Miles Bader
MALLOC_SET_SIZE now takes the user-address rather than the base-address.
2002-07-30MALLOC_SET_SIZE now takes the user-address rather than the base-address.Miles Bader
2002-07-30Define MALLOC_SET_SIZE to take the user-address rather than the base-address.Miles Bader
2002-07-30Implement shrinking.Miles Bader
Fix bug when growing an allocation. Use new malloc header macros.
2002-07-30Use new malloc header macros.Miles Bader
2002-07-30Add macros to abstract the malloc header format a bit.Miles Bader
2002-07-25Size tweaks.Miles Bader
2002-07-25Miscellaneous tidying-up.Miles Bader
2002-07-25Redo the locking, so that it may actually work. Now locking is done atMiles Bader
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.
