- Subject: [PATCH 2/2] openpgm/pgm/checksum.c: fix build with 32 bits MMX
-
- Build with i386-pentium-mmx or i686 is broken since version 5-3-128 and
- https://github.com/steve-o/openpgm/commit/b276dc15be5d4e6e1143b9de25d09f63f9c85135
- because _mm_cvtm64_si64 is undefined resulting in the following build
- failure for example on zeromq:
-
- /srv/storage/autobuild/run/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/i586-buildroot-linux-musl/8.3.0/../../../../i586-buildroot-linux-musl/bin/ld: /srv/storage/autobuild/run/instance-3/output-1/host/i586-buildroot-linux-musl/sysroot/usr/lib32/libpgm-5.3.so.0: undefined reference to `_mm_cvtm64_si64'
-
- So use the fallback if __x86_64__ is not defined
-
- Fixes:
