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.
