Macro Definition Documentation

◆ __GLIBC_PREREQ

#define __GLIBC_PREREQ	(		MAJOR,
			MINOR )

Value:

0

Definition at line 25 of file features.h.

◆ HAVE_BITCOUNT_INTRINSICS

#define HAVE_BITCOUNT_INTRINSICS 0

Do we have the bit-counting intrinsics?

Definition at line 80 of file features.h.

◆ HAVE_CONVERT_VECTOR

#define HAVE_CONVERT_VECTOR 0

Definition at line 97 of file features.h.

◆ HAVE_FEENABLEEXCEPT

#define HAVE_FEENABLEEXCEPT 0

Definition at line 120 of file features.h.

◆ HAVE_FUNCTION_MULTIVERSIONING

#define HAVE_FUNCTION_MULTIVERSIONING 0

Do we have function multiversioning?

GCC and clang support the target attribute

Definition at line 46 of file features.h.

◆ HAVE_GCC_CLANG_EXTENSIONS

#define HAVE_GCC_CLANG_EXTENSIONS 0

Do we support the compatible set of GCC and clang extensions These are our main compilers.

Definition at line 35 of file features.h.

◆ HAVE_GCC_INTRINSICS

#define HAVE_GCC_INTRINSICS 0

Do we have support for all GCC intrinsics?

Definition at line 64 of file features.h.

◆ HAVE_MALLINFO2

#define HAVE_MALLINFO2 0

Definition at line 105 of file features.h.

◆ HAVE_MALLOC_HOOKS

#define HAVE_MALLOC_HOOKS 1

Definition at line 111 of file features.h.

◆ HAVE_STD_RANGES

#define HAVE_STD_RANGES 0

Definition at line 127 of file features.h.

◆ HAVE_TARGET_CLONES

#define HAVE_TARGET_CLONES 0

Do we additionally have the target_clones attribute?

GCC and clang >=14 support it. ...But at least for GCC11 and clang 14 in order to work for both we have to apply it to a declaration (for clang) that is also definition (for GCC)

Definition at line 57 of file features.h.

◆ HAVE_VECTOR_SIZE_ATTRIBUTE

#define HAVE_VECTOR_SIZE_ATTRIBUTE 0

Definition at line 88 of file features.h.
