genksyms: Track changes to enum constants

2011-03-17T14:13:56+00:00

Enum constants can be used as array sizes; if the enum itself does not
appear in the symbol expansion, a change in the enum constant will go
unnoticed. Example patch that changes the ABI but does not change the
checksum with current genksyms:

| enum e {
|	E1,
|	E2,
|+	E3,
|	E_MAX
| };
|
| struct s {
|	int a[E_MAX];
| }
|
| int f(struct s *s) { ... }
| EXPORT_SYMBOL(f)

Therefore, remember the value of each enum constant and
expand each occurence to  . The value is not actually
computed, but instead an expression in the form
(last explicitly assigned value) + N
is used. This avoids having to parse and semantically understand whole
of C.

Note: The changes won't take effect until the lexer and parser are
rebuilt by the next patch.

genksyms: simplify usage of find_symbol()

2011-03-17T14:13:55+00:00

Allow searching for symbols of an exact type. The lexer does this and a
subsequent patch will add one more usage.

genksyms: Simplify printing of symbol types

2011-03-17T14:13:55+00:00

Instead of special-casing SYM_NORMAL, do not map any name to it. Also
explicitly set the single-letter name of the symbol type, which will be
needed by a further patch. The only user-visible change is one debug
printf.

genksyms: Do not paste the bison header file to lex.c

2011-03-17T14:13:55+00:00

The header is already #included, no need to include it a second time.
lex.c_shipped was regenerated using flex-2.5.35.

FreeBSD does not like  when __STDC__ is defined, use the standard
 instead.

It is the last place when the file is read, so close it.

genksyms: properly consider EXPORT_UNUSED_SYMBOL{,_GPL}()

2009-12-12T12:08:16+00:00

Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing.  But I also think this is
one of the reasons why __crc_* need to be weak (which I think should be
avoided, and hence we should have the goal to eliminate this so that
failure to calculate a proper CRC for a symbol causes the build to fail).
