WebThis was fixed in -fabi-version=3.. SIMD vector types declared using __attribute ((vector_size)) were mangled in a non-standard way that does not allow for overloading of functions taking vectors of different sizes.. The mangling was changed in -fabi-version=4.. __attribute ((const)) and noreturn were mangled as type qualifiers, and decltype of a … WebThe integer data types range in size from at least 8 bits to at least 32 bits. The C99 standard extends this range to include integer sizes of at least 64 bits. You should use integer types for storing whole number values (and the char data type for storing characters). The sizes and ranges listed for these types are minimums; depending on …
