2008-02-27*: add optimization barrier to all "G trick" locationsDenis Vlasenko
2007-10-13bzip2: port bzip2 1.0.4 to busybox. note: bzip2 code residesDenis Vlasenko
in separate directory (archival/bz/*) and is covered by BSD-style license. code size: 13k
2007-10-11add -fvisibility=hidden to CC flags, mark XXX_main functionsDenis Vlasenko
EXTERNALLY_VISIBLE. 5% size reduction of libbusybox.so
2007-09-27introduce bb_putchar(). saves ~1800 on uclibc (less on glibc).Denis Vlasenko
2007-08-18don't pass argc in getopt32, it's superfluousDenis Vlasenko

2007-08-12trylink: produce even more info about final link stageDenis Vlasenko
trylink: explain how to modify link and drastically decrease amount of padding (unfortunately, needs hand editing ATM). *: add ALIGN1 / ALIGN2 to global strings and arrays of bytes and shorts size saving: 0.5k

2007-04-12style fixes. No code changesDenis Vlasenko
2007-04-10make compressed help code NOMMU- and NOFORK-friendly -Denis Vlasenko
no forking anymore, bunzip2 unpack routine now does all it in memory.

2007-03-15fix TODO: getopt32 should reset optind to 1 itselfDenis Vlasenko
2007-03-15modify ptr_to_globals trick so that we do not violateDenis Vlasenko
type safety (well, sort of ;))

2007-01-07gzip cleanup part #2Denis Vlasenko
2007-01-07a ton of gzip changes, split up in compiled andDenis Vlasenko
run-tested pieces. Code was rather messy. It's not a bug fix, more like code cleanup. This is the first part.
2007-01-06kill unused variableDenis Vlasenko
2006-12-30done a dozen of randconfig test. guess what? ALL failed...Denis Vlasenko
these are resulting fixes
2006-12-22remove useless casts (type*) xzalloc(...)Denis Vlasenko
2006-12-18A bunch of defined(__GLIBC__) added. static-linking warning expandedDenis Vlasenko
2006-12-16inline strcmp(s, "-") [actually macro-ize it for now - gcc is too stupid]Denis Vlasenko
2006-11-27style cleanup: return(a) -> return a, part 2Denis Vlasenko
2006-10-03getopt_ulflags -> getopt32.Denis Vlasenko
It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.
2006-10-01gzip: add a bit of comment. The code itselfDenis Vlasenko
is too bloated to work on it...
2006-10-01g[un]zip: add support for -v (verbose).Denis Vlasenko
Add CONFIG_DESKTOP, almost all bloat from this change is hidden under that.
2006-09-22gzip: getopt_ulflags'isationDenis Vlasenko
2006-09-11- convert a few xopen3(,,0) into xopen(,). Also peruse the fact that xopen ↵Bernhard Reutner-Fischer
defaults to 0777 on it's own, so we don't need to xopen3(,,0777).

2006-09-09using [xa]sprintf for string concatenation is neat and savesDenis Vlasenko
~100 bytes according to bloatcheck. Also this fixes bug in rpm
