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].
|
||
|
|

||
