kbuild: modversions for EXPORT_SYMBOL() for asm

2018-01-23T18:50:17Z

commit 4efca4ed05cbdfd13ec3e8cb623fb77d6e4ab187 upstream. Allow architectures to create asm/asm-prototypes.h file that provides C prototypes for exported asm functions, which enables proper CRC versions to be generated for them.

ftrace: allow architectures to specify ftrace compile options

2015-01-29T08:19:19Z

If the kernel is compiled with function tracer support the -pg compile option is passed to gcc to generate extra code into the prologue of each function. This patch replaces the "open-coded" -pg compile flag with a CC_FLAGS_FTRACE makefile variable which architectures can override if a different option should be used for code generation.

kbuild: remove obj-n and lib-n handling

2014-10-02T11:55:02Z

Kconfig never defines CONFIG_* as 'n'. Now obj-n is only used in firmware/Makefile and it can be replaced with obj-. No makefile uses lib-n. Let's rip off obj-n and lib-n. Signed-off-by: Masahiro Yamada Acked-by: Peter Foley Signed-off-by: Michal Marek

kbuild: handle multi-objs dependency appropriately

2014-08-19T08:26:19Z

The comment in scripts/Makefile.build says as follows: We would rather have a list of rules like foo.o: $(foo-objs) but that's not so easy, so we rather make all composite objects depend on the set of all their parts This commit makes it possible! For example, assume a Makefile like this obj-m = foo.o bar.o foo-objs := foo1.o foo2.o bar-objs := bar1.o bar2.o Without this patch, foo.o depends on all of foo1.o foo2.o bar1.o bar2.o. It looks funny that foo.o is regenerated when bar1.c is updated. Now we can handle the dependency of foo.o and bar.o separately. Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

kbuild: move extra gcc checks to scripts/Makefile.extrawarn

2014-04-16T21:28:41Z

W=... provides extra gcc checks. Having such code in scripts/Makefile.build results in the same flags being added to KBUILD_CFLAGS multiple times becuase scripts/Makefile.build is invoked every time Kbuild descends into the subdirectories. Since the top Makefile is already too cluttered, this commit moves all of extra gcc check stuff to a new file scripts/Makefile.extrawarn, which is included from the top Makefile.

kbuild: LLVMLinux: Adapt warnings for compilation with clang

When compiling kernel with clang, disable warnings which are too noisy, and add the clang flag catch-undefined-behavior. Signed-off-by: Jan-Simon Möller Signed-off-by: Behan Webster Signed-off-by: Mark Charlebois Cc: PaX Team

Kbuild, lto: Disable LTO for asm-offsets.c

The asm-offset.c technique to fish data out of the assembler file does not work with LTO. Just disable for the asm-offset.c build. Signed-off-by: Andi Kleen Link: http://lkml.kernel.org/r/1391846481-31491-11-git-send-email-ak@linux.intel.com Signed-off-by: H. Peter Anvin

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

X.509: Add simple ASN.1 grammar compiler

2012-10-08T03:20:19Z

Add a simple ASN.1 grammar compiler. This produces a bytecode output that can be fed to a decoder to inform the decoder how to interpret the ASN.1 stream it is trying to parse. Action functions can be specified in the grammar by interpolating: ({ foo }) after a type, for example: SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, subjectPublicKey BIT STRING ({ do_key_data }) } The decoder is expected to call these after matching this type and parsing the contents if it is a constructed type. The grammar compiler does not currently support the SET type (though it does support SET OF) as I can't see a good way of tracking which members have been encountered yet without using up extra stack space. Currently, the grammar compiler will fail if more than 256 bytes of bytecode would be produced or more than 256 actions have been specified as it uses 8-bit jump values and action indices to keep space usage down.
