genksyms: Use same type in loop comparison

2011-07-25T12:55:17Z

The ARRAY_SIZE macro in scripts/genksyms/genksyms.c returns a value of type size_t. That value is being compared to a variable of type int in a loop in read_node(). Change the int variable to size_t type as well, so we don't do signed vs unsigned type comparisons with all the potential promotion/sign extension trouble that can cause (also silences compiler warnings at high levels of warnings).

genksyms: pass hash and lookup functions name and target language though the input file

2011-06-09T18:04:40Z

Renaming hash and lookup functions on the command line would reduces its genericity. Use the .gperf file to pass this information. Do the same for the target language. Signed-off-by: Arnaud Lacombe

genksyms: Track changes to enum constants

2011-03-17T14:13:56Z

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. Signed-off-by: Michal Marek Acked-by: Sam Ravnborg

genksyms: simplify usage of find_symbol()

2011-03-17T14:13:55Z

Allow searching for symbols of an exact type. The lexer does this and a subsequent patch will add one more usage. Signed-off-by: Michal Marek Acked-by: Sam Ravnborg

genksyms: Simplify printing of symbol types

2011-03-17T14:13:55Z

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. Signed-off-by: Michal Marek Acked-by: Sam Ravnborg
