- Subject: [PATCH] powerpc: fix build failure on power7 and older (#532)
-
- Build failure looks as:
- ```
- libtool: compile: powerpc-unknown-linux-gnu-gcc \
- -O2 -mcpu=powerpc -mtune=powerpc -pipe ... -c src/powerpc/ffi.c ...
- In file included from src/powerpc/ffi.c:33:
- src/powerpc/ffi_powerpc.h:65:9: error: '__int128' is not supported on this target
- 65 | typedef __int128 float128;
- | ^~~~~~~~
- ```
-
- The fix avoids using __int128 in favour of aligned char[16].
-
- Closes: https://github.com/libffi/libffi/issues/531
- Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
