| Add RISC-V endian detection |
| |
| 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. |
