2020-11-10	opt: Assert that we don't do disabled optimizations	Tavian Barnes

2020-11-09	opt: Predicates aren't true when they're false	Tavian Barnes
	This unfortunate typo was mostly harmless; since the predicates were always assumed to be true, they wouldn't conflict. The exception is -user/-group, which set -nouser/-nogroup to false for users/groups that exist. Even -O0 wasn't enough to suppress the bug, due to a missing optlevel check fixed in the previous commit. Fixes: 305ee902874b49351f4916e303c293523f11570b
2020-11-09	opt: Check optlevel before removing unreachable expressions	Tavian Barnes

2020-11-09	Use two newlines for all pre-eval warnings	Tavian Barnes

2020-09-27	Rename struct cmdline to bfs_ctx	Tavian Barnes
	The API remains similar, with some added accessor functions for lazy initialization of the pwcache and mtab.
2020-07-29	bftw: Rename bftw_typeflag to bftw_type, and make it not a bitmask	Tavian Barnes

2020-06-07	opt: Warn when no side effects are reachable	Tavian Barnes

2020-06-07	opt: Dump the command line before optimizing with -D opt	Tavian Barnes

2020-06-07	parse: Prohibit actions inside -exclude	Tavian Barnes

2020-06-07	Implement -exclude, a special form for convenient exclusions	Tavian Barnes
	Fixes #8.
2020-06-07	opt: Make sure facts_when_impure sees all impure literals	Tavian Barnes

2020-06-02	diag: Unify debug printing	Tavian Barnes

2020-05-22	opt: Add missing #include <unistd.h>	Tavian Barnes

2020-05-22	opt: Track data flow information about predicates	Tavian Barnes
	This allows us to optimize things like -sparse -o -not -sparse <==> -true and -sparse -a -not -sparse <==> -false
2020-03-23	opt: Avoid dangling pointers in de_morgan()	Tavian Barnes
	If optimize_{and,or}_expr() relocates expr, we need to update the parent expr or else we might return garbage. It seems impossible to actually trigger this bug right now, since the {and,or} optimizations are symmetric, but it could be hit if the simplifications in de_morgan() expose more information than was known previously.
2019-04-15	Release 1.41.4	Tavian Barnes

2019-03-21	opt: Optimize redundant comma expressions	Tavian Barnes

2019-03-20	opt: Replace -a -false/-o -true with -not when possible	Tavian Barnes

2019-02-09	Add some documentation comments	Tavian Barnes

2019-02-04	opt: Optimize -samefile together with -inum	Tavian Barnes

2019-02-01	opt: Apply data flow optimizations to more numeric ranges	Tavian Barnes

2019-01-02	color: Check format strings + args for cfprintf()	Tavian Barnes
	%{cc} is now ${cc} to avoid warnings about an unrecognized format specifier, and %P and %L are now %pP and %pL to make them look more like standard format strings.
2018-09-24	Update copyright dates	Tavian Barnes

2018-08-18	opt: Re-run optimizations after reordering expressions	Tavian Barnes
	This catches new data flow inferences that can be made after swapping the children of an expression.
2017-12-15	Keep track of required FDs per-expr	Tavian Barnes

2017-09-17	opt: More -O4 tweaks	Tavian Barnes

2017-09-17	opt: Use the standard LLONG_MAX instead of the nonstandard LONG_LONG_MAX	Tavian Barnes

2017-09-17	opt: Fix -depth with arguments bigger than INT_MAX	Tavian Barnes

2017-09-17	opt: Move some aggressive optimizations back to -O4	Tavian Barnes

2017-09-17	opt: Have data flow analysis respect always_{true,false}	Tavian Barnes

2017-09-16	opt: Implement some data flow optimizations	Tavian Barnes

2017-09-16	opt: Separate optimization from parsing	Tavian Barnes
