cgd bb7cdd7c0b don't bother initializing 'freelist' -- it can be bss 1999-05-28 19:31:51 +00:00
simonb fa38a5236c The "found" label is not used if ALLOC_FIRST_FIT is defined. 1999-04-11 04:02:37 +00:00

drochner 9f58a1a9bb fix printf() format warnings in debug output 1997-09-17 16:24:00 +00:00
drochner a8ac47dd1b Fix syntax error which appeared #ifdef DEBUG ("end[]").
Simplify the heap location stuff.

drochner a1d00666ac Allow to define the location of the heap at runtime #if HEAP_VARIABLE.
That helps to test libsa code in user space.

leo 2242daf790 Initialize 'bestf' to make this compile again with -Wall. 1997-02-16 13:02:59 +00:00
thorpej 63930d7db4 Add some debugging code to free(), to catch frees before the
start of the heap and beyond the end of the heap (if a heap limit
is defined).

cgd ea27b7aa31 Add a whole bunch of features, from Matthias Drochner:
best-fit, rather than first-fit, algorithm.
	ability to handle free()s with zero size (needed for gzip read
	    support).
	ability to start the heap someplace else (defined by HEAP_START).
	ability to limit growth of the heap (via HEAP_LIMIT).
	debugging sanity checks (ifdef DEBUG).
	allocation tracing support, to help debugging (ifdef ALLOC_TRACE).
and from me:
	ability to pick a (smaller) first-fit algorithm (via ALLOC_FIRST_FIT).
	lots of comments.

If heap limits and all of the debugging features are disabled (the default),
and ALLOC_FIRST_FIT is defined (not the default), compiled with -O on the
alpha the new version is the same (object) size as the old version.
