Begin to add `long long` to C compiler for linux386. Add long long type, but without literals; you can't say '123LL' yet. You can try constant operations, like `(long long)123 + 1`, but the compiler's `arith` type might not be wide enough. Conversions, shifts, and some other operations don't work in i386 ncg; I am using a union instead of conversions: union q { long long ll; unsigned long long ull; int i[2]; }; Hack plat/linux386/descr to enable long long (size 8, alignment 4) only for this platform. The default for other platforms is to disable long long (size -1). In lang/cem/cemcom.ansi, - BigPars, SmallPars: Add default size, alignment of long long. - align.h: Add lnglng_align. - arith.c: Convert arithmetic operands to long long or unsigned long long when necessary; avoid conversion from long long to long. Allow long long as an arithmetic, integral, or logical operand. - ch3.c: Handle long long like int and long when erroneously applying a selector, like `long long ll; ll.member` or `ll->member`. Add long long to integral and arithmetic types. - code.c: Add long long to type stabs for debugging. - conversion.c: Add long long to integral conversions. - cstoper.c: Write masks up to full_mask[8]. Add FIXME comment. - declar.g: Parse `long long` in code. - decspecs.c: Understand long long in type declarations. - eval.c: Add long long to operations, to generate code like `adi 8`. Don't use `ldc` with constant over 4 bytes. - ival.g: Allow long long in initializations. - main.c: Set lnglng_type and related values. - options.c: Add option like `-Vq8.4` to set long long to size 8, alignment 4. I chose 'q', because Perl's pack and Ruby's Array#pack use 'q' for 64-bit or long long values; it might be a reference to BSD's old quad_t alias for long long. - sizes.h: Add lnglng_size. - stab.c: Allow long long when writing the type stab for debugging. Switch from calculating the ranges to hardcoding them in strings; add 8-byte ranges as a special case. This also hardcodes the unsigned 4-byte range as "0;-1". Before it was either "0;-1" or "0;4294967295", depending on sizeof(long) in the compiler. - struct.c: Try long long bitfield, but it will probably give the error, "bit field type long long does not fit in a word". - switch.c: Update comment. - tokenname.c: Define LNGLNG (long long) like LNGDBL (long double). - type.c, type.str: Add lnglng_type and ulnglng_type. Add function no_long_long() to check if long long is disabled.
