SIMD predefs depend on compiler options. For example, you will have to
add the option -msse3
to clang or gcc to enable SSE3. SIMD predefs are also inclusive. This means
that if SSE3 is enabled, then every other extensions with a lower version
number will implicitly be enabled and detected. However, some extensions
are CPU specific, they may not be detected nor enabled when an upper version
is enabled.
Note | |
---|---|
SSE(1) and SSE2 are automatically enabled by default when using x86-64 architecture. |
To check if any SIMD extension has been enabled, you can use:
#include <boost/predef/hardware/simd.h> #include <iostream> int main() { #if defined(BOOST_HW_SIMD_AVAILABLE) std::cout << "SIMD detected!" << std::endl; #endif return 0; }
When writing SIMD specific code, you may want to check if a particular
extension has been detected. To do so you have to use the right architecture
predef and compare it. Those predef are of the form BOOST_HW_SIMD_"ARCH"
(where "ARCH"
is either ARM
, PPC
, or X86
).
For example, if you compile code for x86 architecture, you will have to
use BOOST_HW_SIMD_X86
.
Its value will be the version number of the most recent SIMD extension
detected for the architecture.
To check if an extension has been enabled:
#include <boost/predef/hardware/simd.h> #include <iostream> int main() { #if BOOST_HW_SIMD_X86 >= BOOST_HW_SIMD_X86_SSE3_VERSION std::cout << "This is SSE3!" << std::endl; #endif return 0; }
Note | |
---|---|
The _VERSION defines that map version number to actual real identifiers. This way it is easier to write comparisons without messing up with version numbers. |
To "stricly" check the most recent detected extension:
#include <boost/predef/hardware/simd.h> #include <iostream> int main() { #if BOOST_HW_SIMD_X86 == BOOST_HW_SIMD_X86_SSE3_VERSION std::cout << "This is SSE3 and this is the most recent enabled extension!" << std::endl; #endif return 0; }
Because of the version systems of predefs and of the inclusive property of SIMD extensions macros, you can easily check for ranges of supported extensions:
#include <boost/predef/hardware/simd.h> #include <iostream> int main() { #if BOOST_HW_SIMD_X86 >= BOOST_HW_SIMD_X86_SSE2_VERSION &&\ BOOST_HW_SIMD_X86 <= BOOST_HW_SIMD_X86_SSSE3_VERSION std::cout << "This is SSE2, SSE3 and SSSE3!" << std::endl; #endif return 0; }
Note | |
---|---|
Unlike gcc and clang, Visual Studio does not allow you to specify precisely the SSE variants you want to use, the only detections that will take place are SSE, SSE2, AVX and AVX2. For more informations, see here. |

BOOST_ENDIAN_*
Detection of endian memory ordering. There are four defined macros in this header that define the various generally possible endian memory orderings:
BOOST_ENDIAN_BIG_BYTE
,
byte-swapped big-endian.
BOOST_ENDIAN_BIG_WORD
,
word-swapped big-endian.
BOOST_ENDIAN_LITTLE_BYTE
,
byte-swapped little-endian.
BOOST_ENDIAN_LITTLE_WORD
,
word-swapped little-endian.
The detection is conservative in that it only identifies endianness that it knows for certain. In particular bi-endianness is not indicated as is it not practically possible to determine the endianness from anything but an operating system provided header. And the currently known headers do not define that programatic bi-endianness is available.
This implementation is a compilation of various publicly available information and acquired knowledge:
BOOST_PREDEF_WORKAROUND
BOOST_PREDEF_WORKAROUND(symbol,comp,major,minor,patch)
Usage:
#if BOOST_PREDEF_WORKAROUND(BOOST_COMP_CLANG,<,3,0,0) // Workaround for old clang compilers.. #endif
Defines a comparison against two version numbers that depends on the definion
of BOOST_STRICT_CONFIG
. When
BOOST_STRICT_CONFIG
is defined
this will expand to a value convertible to false
.
Which has the effect of disabling all code conditionally guarded by BOOST_PREDEF_WORKAROUND
. When BOOST_STRICT_CONFIG
is undefine this expand
to test the given symbol
version value with the comp
comparison against BOOST_VERSION_NUMBER(major,minor,patch)
.
BOOST_PREDEF_TESTED_AT
BOOST_PREDEF_TESTED_AT(symbol,major,minor,patch)
Usage:
#if BOOST_PREDEF_TESTED_AT(BOOST_COMP_CLANG,3,5,0) // Needed for clang, and last checked for 3.5.0. #endif
Defines a comparison against two version numbers that depends on the definion
of BOOST_STRICT_CONFIG
and
BOOST_DETECT_OUTDATED_WORKAROUNDS
.
When BOOST_STRICT_CONFIG
is defined this will expand to a value convertible to false
.
Which has the effect of disabling all code conditionally guarded by BOOST_PREDEF_TESTED_AT
. When BOOST_STRICT_CONFIG
is undefined this expand
to either:
true
when BOOST_DETECT_OUTDATED_WORKAROUNDS
is not defined.
true
when the expansion of BOOST_PREDEF_WORKAROUND(symbol, <=, major, minor, patch)
is true
and BOOST_DETECT_OUTDATED_WORKAROUNDS
is
defined.
BOOST_PREDEF_WORKAROUND(symbol, >, major, minor, patch)
is true and BOOST_DETECT_OUTDATED_WORKAROUNDS
is defined.
BOOST_VERSION_NUMBER
BOOST_VERSION_NUMBER(major,minor,patch)
Defines standard version numbers, with these properties:
major
number can
be in the [0,99] range.
minor
number can
be in the [0,99] range.
patch
number can
be in the [0,99999] range.
BOOST_VERSION_NUMBER_MAJOR(N), BOOST_VERSION_NUMBER_MINOR(N), BOOST_VERSION_NUMBER_PATCH(N)
The macros extract the major, minor, and patch portion from a well formed version number resulting in a preprocessor expression in the range of [0,99] or [0,99999] for the major and minor, or patch numbers respectively.
BOOST_PREDEF_MAKE_..
