# bitfields reversed for compatibility with (g)cc.

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.
