2002-08-06Changed fflush() behavior to no-op for r/w streams in read-mode.Manuel Novoa III
This falls under undefined behavior wrt ANSI/ISO C99, but SUSv3 seems to treat it as a no-op and it occurs in some apps. Fixed a problem with _stdio_fwrite() not checking for underlying write() failures. Fixed both _stdio_fwrite() and _stdio_fread() to make sure that the putc and getc macros were disabled if the stream was in and error state. The above changes should take care of a problem initially reported by "Steven J. Hill" <sjhill@realitydiluted.com>.
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
2002-08-06Just in case, crash if somehow `exit' returns anywaysEric Andersen

2002-08-05remove BUILDTIME since it is not usedEric Andersen
2002-08-03A couple of little cleanups I forgot to check in.Manuel Novoa III
2002-08-03When DODEBUG and HAS_WCHAR were enabled and HAS_LOCALE was disabled,Eric Andersen
wchar.c wouldn't compile: wchar.c: In function `__mbsnrtowcs': wchar.c:631: `__ctype_encoding_7_bit' undeclared (first use in this function) This fixes it by keeping the locale specific asserts hidden when not relevant. -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.
2002-08-01Joseph Chiu <josephc@idealab.com> found an off-by-one bug. oops!Eric Andersen
2002-07-31In the allocate-and-copy case, don't include the malloc header in ourMiles Bader
size calculations.
2002-07-31Sigh. A bit more cleanup.Eric Andersen
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
2002-07-31More i960 supportEric Andersen
2002-07-31Patch from Martin Proulx <mproulx@okiok.com> to fix i960Eric Andersen
create_module() support.
2002-07-31Patch from Alexander Pevzner <pzz@pzz.msk.ru> to fixup things when invoked asEric Andersen
the C++ compiler to to automagically add include/g++ into the include search path, and automagically add -lstdc++ and -lm into the set of automatically linked libraries.
2002-07-31You fool foolish. Goodbye level 2.Eric Andersen
2002-07-31Always build utils by defaultEric Andersen

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
2002-07-27Avoid errors in case some loon has explicitly includedEric Andersen
linux/kernel.h (even though doing so is very dumb). -Erik
2002-07-27Oops. I accidentally omitted the actual mknod() function.Eric Andersen
-Erik
2002-07-26Ok, I get it. sjhill kept adding the 'find' command sinceEric Andersen
include/sgidefs.h wasn't getting scrubbed. Fix it so this symlink gets properly scrubbed, even for mipsel. -Erik
2002-07-26Kill ill advised find command that was not doing anythingEric Andersen
productive, but did annoying things instead. -Erik
2002-07-26The __set_errno macro _must_ match that defined in include/bits/errno.h. WeEric Andersen
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
2002-07-25Addition to 'distclean' for little endian MIPS."Steven J. Hill"
2002-07-25ldso specific syscalls and userspace syscalls all in one file now."Steven J. Hill"
2002-07-25Cleanup from Neal Crook fixing some formatting and eliminatingEric Andersen
some "sh: cd: ./lib: No such file or directory" errors.
2002-07-25Kill cruft. Build ldd for the host system by default.Eric Andersen
-Erik
2002-07-25Implement syscall() for armEric Andersen
-Erik
2002-07-25Size tweaks.Miles Bader
2002-07-25Miscellaneous tidying-up.Miles Bader
2002-07-25Take advantage of the new syscall stuff on x86 and arm to killEric Andersen
the ldso specific syscalls and use the generic ones instead. -Erik
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.
2002-07-24Add support for people calling syscall()Eric Andersen
-Erik
2002-07-24Remove source files that, well, no longer exist :)."Steven J. Hill"
2002-07-24This rule is only necessary for little endian MIPS."Steven J. Hill"
2002-07-24Factor out some common code sequences into inline functions.Miles Bader
2002-07-24Misc small cleanups.Miles Bader
2002-07-24Remove, since it's entirely incorrectMiles Bader

(__ASMNAME2): Macro removed.
