-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 [@https://msdn.microsoft.com/en-us/library/b0084kay.aspx here].]

+= Using the `BOOST_HW_SIMD_*` predefs

- [/ --------------------------- ]
+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.

- [section `BOOST_HW_SIMD_*`]
+NOTE: SSE(1) and SSE2 are automatically enabled by default when using x86-64
+architecture.

- [heading `BOOST_HW_SIMD`]
+To check if any SIMD extension has been enabled, you can use:

- The SIMD extension detected for a specific architectures.
- Version number depends on the detected extension.
+[source]
+----
+#include <boost/predef/hardware/simd.h>
+#include <iostream>

- [table
-     [[__predef_symbol__] [__predef_version__]]
+int main()
+{
+#if defined(BOOST_HW_SIMD_AVAILABLE)
+    std::cout << "SIMD detected!" << std::endl;
+#endif
+    return 0;
+}
+----

-     [[`BOOST_HW_SIMD_X86_AVAILABLE`] [__predef_detection__]]
-     [[`BOOST_HW_SIMD_X86_AMD_AVAILABLE`] [__predef_detection__]]
-     [[`BOOST_HW_SIMD_ARM_AVAILABLE`] [__predef_detection__]]
-     [[`BOOST_HW_SIMD_PPC_AVAILABLE`] [__predef_detection__]]
-     ]
+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.

- [include ../include/boost/predef/hardware/simd/x86.h]
- [include ../include/boost/predef/hardware/simd/x86_amd.h]
- [include ../include/boost/predef/hardware/simd/arm.h]
- [include ../include/boost/predef/hardware/simd/ppc.h]
+To check if an extension has been enabled:

- [endsect]
+[source]
+----
+#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;
+}
+----

- [section `BOOST_HW_SIMD_X86_*_VERSION`]
- [include ../include/boost/predef/hardware/simd/x86/versions.h]
- [endsect]
+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.

- [section `BOOST_HW_SIMD_X86_AMD_*_VERSION`]
- [include ../include/boost/predef/hardware/simd/x86_amd/versions.h]
- [endsect]
+To *"strictly"* check the most recent detected extension:

- [section `BOOST_HW_SIMD_ARM_*_VERSION`]
- [include ../include/boost/predef/hardware/simd/arm/versions.h]
- [endsect]
+[source]
+----
+#include <boost/predef/hardware/simd.h>
+#include <iostream>

- [section `BOOST_HW_SIMD_PPC_*_VERSION`]
- [include ../include/boost/predef/hardware/simd/ppc/versions.h]
- [endsect]
+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:
+
+[source]
+----
+#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 [@https://msdn.microsoft.com/en-us/library/b0084kay.aspx here].

Rene Rivera	d990549214	Fix redef of OS_BSD predef. When a BSD sub-os header is included directly the general OS_BSD predef is inidially defined as not-available. Which warns as the sub-os header defines it. The fix is to unconditionally un-def the OS_BSD predef. fixes https://github.com/boostorg/predef/issues/111	2021-01-04 14:37:33 -06:00

Thomas Petazzoni	4bc7cc02ed	Add RISC-V endian detection (#100 ) boost/predef/other/endian.h has two ways of detecting the endianess: (1) It includes <endian.h> if BOOST_LIB_C_GNU is defined, and then use __BYTE_ORDER to decide the endianness. (2) Otherwise, if (1) was not possible for some reason, it uses architecture defines to decide the endianness. (1) works perfectly fine with glibc toolchains, because BOOST_LIB_C_GNU is defined, but it doesn't work with musl. Due to this, <endian.h> is not included, __BYTE_ORDER is not defined, and method (1) does not work, causing build failures on musl toolchains that don't have explicit handling by architecture name (method 2). So this commit fixes RISC-V musl build by adding support for the __riscv architecture define, to determine that the endianness is little endian.
