christos f53f008dfb More cosmetics in the usage message... 1999-05-03 15:45:01 +00:00
christos 5cb75fd417 Now that we use cc -E, -U__GNUC__ to avoid gnu extensions. Nuke the
__attribute__ and __extension__ workarounds.
Our invariant is: No gcc extensions if __GNUC__ is not defined, so lint
should not be playing around trying to pretend it is gcc.

christos e782f12df1 Deal with gcc __extension__({ }). We assume that it returns a value 0, and
we prepend a /*NOSTRICT*/ comment to avoid constant in conditional context
warning.

mrg b30d0fe7ba use "cc -E" not cpp directly. this allows lint(1) to be unaware of any
machine-dependant defines that cc(1) may normally define, and also
means that the mips ports work again.

garbled 9e44e9b578 More and more .Os cleanups. .Os is defined in the tmac.doc-common file,
so we shouldn't override it with versions in the manpages.  Many more to
come.

christos 8f9762f2e2 pass -CC instead of -C to cpp so that we preserve macro comments in place. 1998-12-09 12:28:36 +00:00
christos d79deccee9 Unfortunately lint uses c-style comments as directives and these get parsed
at the lexical analysis stage not at the syntax parsing stage. The upshot
is that:
	if (expr) {
		stmt1;
	}
	/* LINTED */
	stmt2;

stmt2 is the look-ahead token for the parser to choose between and if-then-else
statement as opposed to an if-then statement. Unfortunately the side effect
is that the LINTED directive gets reset before stmt2 gets parsed. We fix this,
by remembering the the linted directive during the if statement parsing and
restoring it at the appropriate time.

christos e79f03e595 Fix problems with LINTED comment:
if (a) b;
	/*LINTED*/
	c;

	if (a) { b; }
	/*LINTED*/
	c;

	do { b; }
	/*LINTED*/
	while (c);

Produced warnings for c.

sommerfe bf7d5c8de3 Add -d option, so lint can be used safely when we're not building "in
place" (e.g., when DESTDIR is set).  This causes the lint driver to
pass -nostdinc -idirafter <dir> to cpp, causing it to ignore
/usr/include and look somewhere else instead..

the function renaming tricks currently needed by libc can be tolerated
by lint.  This needs some cleanup, but it appears to work.

cgd 81f0721bbe * accept the file name '-' to indicate that standard input is to be
used as lint1 input.  That involves having lint pass the '-' through
  to the cpp which preprocesses the lint1 input, and having lint1's
  scanner recognize a cpp filename "" as "{standard input}".

cgd 46b90748f5 * Ignore the size of integer arguments when trying to automatically
convert them to pointers.  If they're zero, they're converted (to
  NULL pointers) regardless of size.  If they're non-zero, they can't
  be converted (without a cast).  This matches the behavior of other
  version of lint, e.g. the lints on Digital UNIX and HP-UX.

* recognize that pointers to identical unnamed and untyped structs,
  unions, and enums are, in fact, identical.  This is done by tagging
  each of unnamed and untyped structure, union and enum with a unique
  position of creation, which is used as a unique identifier that
  when determine whether or not a pair of structures, unions, or enums
  are identical.

cgd e8685ee836 * Accept asm statements at any place where you could see a function or
variable declaration, in addition to within function & variable
  declarations and function bodies.  I think this comes close enough
  to what gcc does to be considered "correct enough."  Certainly, it
  fixes the problem for the couple of cases where this is a problem
  in our tree.
