genksyms: pass symbol-prefix instead of arch

2013-03-20T00:57:27Z

Pass symbol-prefix to genksyms instead of arch, so that the decision what symbol prefix to use is kept in one place. Basically genksyms used to take a -a $ARCH argument and it used that to determine whether to add an underscore symbol prefix. It's now changed to take a -s $SYMBOL_PREFIX argument so that the caller decides whether a symbol prefix is required. The build system then uses CONFIG_HAVE_UNDERSCORE_SYMBOL_PREFIX to determine whether to pass the argument. Signed-off-by: James Hogan Signed-off-by: Rusty Russell

genksyms: fix metag symbol prefix on crc symbols

2013-03-02T20:11:13Z

Meta uses symbol prefixes, so add "metag" to the list of architectures to set the mod_prefix to "_" for. This fixes __crc_* symbols to add the extra underscore to match _CRC_SYMBOL macro in and so that modpost finds them. Signed-off-by: James Hogan

genksyms: Do not expand internal types

2011-10-11T10:00:39Z

Consider structures, unions and enums defined in the source file as internal and do not expand them. This way, changes to e.g. struct serial_private in drivers/tty/serial/8250_pci.c will not affect the checksum of the pciserial_* exports.

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: 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: Add helpers for building string lists

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

genksyms: close ref_file after use

2010-02-02T13:33:55Z

It is the last place when the file is read, so close it. Signed-off-by: Alexander Beregalov Signed-off-by: Michal Marek
