Subject: [PATCH] ffi_powerpc.h: fix build failure with powerpc7
|
||
|
|
|
||
|
|
Sicne commit 73dd43afc8a447ba98ea02e9aad4c6898dc77fb0, build on powerpc7
|
||
|
|
fails on:
|
||
|
|
|
||
|
|
In file included from ../src/powerpc/ffi.c:33:0:
|
||
|
|
../src/powerpc/ffi_powerpc.h:61:9: error: '_Float128' is not supported on this target
|
||
|
|
typedef _Float128 float128;
|
||
|
|
^~~~~~~~~
|
||
|
|
|
||
|
|
Fix this build failure by checking for __HAVE_FLOAT128 before using
|
||
|
|
_Float128, as _Float128 is enabled only on specific conditions, see
|
||
|
|
output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/include/bits/floatn.h:
|
||
|
|
|
||
|
|
/* Defined to 1 if the current compiler invocation provides a
|
||
|
|
floating-point type with the IEEE 754 binary128 format, and this glibc
|
||
|
|
includes corresponding *f128 interfaces for it. */
|
||
|
|
#if defined _ARCH_PWR8 && defined __LITTLE_ENDIAN__ && (_CALL_ELF == 2) \
|
||
|
|
&& defined __FLOAT128__ && !defined __NO_LONG_DOUBLE_MATH
|
||
|
|
# define __HAVE_FLOAT128 1
|
||
|

#else
|

# define __HAVE_FLOAT128 0

#endif
