genksyms: Handle string literals with spaces in reference files

2018-03-01T00:32:20Z

[ Upstream commit a78f70e8d65e88b9f631d073f68cb26dcd746298 ] The reference files use spaces to separate tokens, however, we must preserve spaces inside string literals. Currently the only case in the tree is struct edac_raw_error_desc in : $ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes $ mv drivers/edac/amd64_edac.{symtypes,symref} $ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes drivers/edac/amd64_edac.c:527: warning: amd64_get_dram_hole_info: modversion changed because of changes in struct edac_raw_error_desc Signed-off-by: Michal Marek Signed-off-by: Sasha Levin

genksyms: fix typeof() handling

2014-04-03T23:20:52Z

Recent increased use of typeof() throughout the tree resulted in a number of symbols (25 in a typical distro config of ours) not getting a proper CRC calculated for them anymore, due to the parser in genksyms not coping with several of these uses (interestingly in the majority of [if not all] cases the problem is due to the use of typeof() in code preceding a certain export, not in the declaration/definition of the exported function/object itself; I wasn't able to find a way to address this more general parser shortcoming). The use of parameter_declaration is a little more relaxed than would be ideal (permitting not just a bare type specification, but also one with identifier), but since the same code is being passed through an actual compiler, there's no apparent risk of allowing through any broken code. Otoh using parameter_declaration instead of the ad hoc "decl_specifier_seq '*'" / "decl_specifier_seq" pair allows all types to be handled rather than just plain ones and pointers to plain ones.

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

scripts/genksyms: clean lex/yacc generated files

2012-01-08T13:48:15Z

Add "keywords.hash.c", "lex.lex.c", "parse.tab.c" and "parse.tab.h" to clean-list so that they get automagically deleted at clean/mrproper time. Signed-off-by: Fernando Luis Vazquez Cao Signed-off-by: Michal Marek

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: Minor parser cleanup

2011-10-11T09:59:19Z

Move the identical logic for recording a struct/union/enum definition to a function.

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).
