Colin Percival 5fe69bb518 Setting a variable to the same value twice doesn't actually make it 
more likely to have the right value.  Remove superfluous assignments.

Found by:	LLVM/Clang Static Checker
 2008-08-04 06:39:52 +00:00
Colin Percival f9bcf9cabf Mark functions as __dead2 in order to help the LLVM static checker 
understand which code paths aren't possible.

This commit eliminates 117 false positive bug reports of the form
"allocate memory; error out if pointer is NULL; use pointer".

Xin LI c1613cd50a Indent the else path, reduce diff against OpenBSD. 2008-07-18 23:35:31 +00:00
Kevin Lo 068d36032a Fix a longstanding bug, from Otto Moerbeck: 
if we're reducing a rule that has an empty
right hand side and the yacc stackpointer is pointing at the very
end of the allocated stack, we end up accessing the stack out of
bounds by the implicit $$ = $1 action

David Malone 9f5b04e925 Style improvements recommended by Bruce as a follow up to some 
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Warner Losh bc505f7742 Only use __FBSDID if it is defined. This fixes the 4.4-release (but 
not stable) -> current upgrade path.

are used in executable.

Bruce Evans 87be6e697a Fixed breakage of K&R support in rev.1.26. yyparse() was defined as 
`int yyparse(;) ; { ... }' in K&R mode.  Getting rid of the second
unwanted semicolon in this made the ifdef tangle more tangled than
before.  Fixed a backwards comment in the tangle.
