卜部昌平 e9fb2bc873 RBIMPL_ALIGNOF: do not use __alignof__ ... It is reported that on a system of i386 System V ABI, GCC returns 8 for __alignof__(double). OTOH the ABI defines alignments of double to be 4, and ISO/IEC 9899:2011 reads that _Alignof(double) shall return 4 on such machine. What we want in ruby is 4 instead of 8 there. We cannot use __alignof__. Additionally, both old GCC / old clang return 8 for _Alignof(double) on such platforms. They are their bugs, and already fixed in recent versions. But we have to support older compilers for a while. Shall check sanity of _Alignof.		2020-09-25 11:38:33 +09:00
