linux-toradex.git/tools/include/linux/compiler-gcc.h, branch v4.14-rc7

tools include linux: Guard against redefinition of some macros

2017-09-12T15:33:39+00:00

When cross building to android r15c (and older versions) on Fedora 26
we notice these:

/opt/android-ndk-r15c/platforms/android-24/arch-arm/usr/include/sys/cdefs.h:332:0: note: this is the location of the previous definition

For __aligned, __packed and __noreturn, so guard those with ifdefs to
avoid drowning useful warnings in these.

tools: Adopt __aligned from kernel sources

2017-06-19T18:27:08+00:00

To have a more compact way to ask the compiler to use a specific
alignment, making tools/ look more like kernel source code.

tools: Adopt __packed from kernel sources

2017-06-19T18:27:07+00:00

To have a more compact way to ask the compiler to not insert alignment
paddings in a struct, making tools/ look more like kernel source code.

tools: Adopt noinline from kernel sources

2017-06-19T18:27:06+00:00

tools: Adopt __printf from kernel sources

2017-06-19T18:25:26+00:00

To have a more compact way to ask the compiler to perform printf like
vargargs validation.

v2: Fixed up build on arm, squashing a patch by Kim Phillips, thanks!

tools: Adopt __noreturn from kernel sources

2017-06-19T18:14:58+00:00

To have a more compact way to specify that a function doesn't return,
instead of the open coded:

	__attribute__((noreturn))

And use it instead of the tools/perf/ specific variation, NORETURN.

tools include: Adopt __same_type() and __must_be_array() from the kernel

2017-04-19T16:01:42+00:00

Will be used to adopt the more stringent version of ARRAY_SIZE(), the
one in the kernel sources.

tools include: Adopt __compiletime_error

2017-03-03T22:07:13+00:00

From the kernel, get the gcc one and provide the fallback so that we can
continue build with other compilers, such as with clang.

Will be used by tools/arch/x86/include/asm/cmpxchg.h.

2017-02-13T17:29:29+00:00

To match the kernel headers structure, setting up things that are
specific to gcc or to some specific version of gcc.

It gets included by linux/compiler.h when gcc is the compiler being
used.
