Rui Ueyama	9c36dd727c	Make "main" to implicitly return 0	2020-12-07 12:00:06 +09:00
Rui Ueyama	5257ee0f20	Make an array of at least 16 bytes long to have alignment of at least 16 bytes ... Quote from AMD64 System V ABI: "An array uses the same alignment as its elements, except that a local or global array variable of length at least 16 bytes or a C99 variable-length array variable always has alignment of at least 16 bytes."	2020-12-07 12:00:06 +09:00

Rui Ueyama	dcd4579226	Handle a function returning bool, char or short ... x86-64 psABI says that only the least significant 8 bits are significant if RAX has a return value of a function returning bool. Likewise, it looks like only the least significant 1 or 2 bytes are guaranteed to have a correct value for char and short return values, respectively.	2020-12-07 12:00:06 +09:00

Rui Ueyama	44bba965cb	Add _Bool type ... _Bool isn't just a 1-bit integer because when you convert a value to bool, the result is 1 if the original value is non-zero. This is contrary to the other small integral types, e.g. char, as you can see below: char x = 256; // x is 0 _Bool y = 256; // y is 1	2020-12-07 12:00:05 +09:00
