For now, a long long literal must have the 'LL' or 'll' suffix. A
literal without 'LL' or 'll' acts as before: it may become unsigned
long but not long long. (For targets where int and long have the same
size, some literals change from unsigned int to unsigned long.)
Type `arith` may be too narrow for long long values. Add a second
type `writh` for wide arithmetic, and change some variables from arith
to writh. This may cause bugs if I forget to use writh, or if a
conversion from writh to arith overflows. I mark some conversions
with (arith) or (writh) casts.
- BigPars, SmallPars: Remove SPECIAL_ARITHMETICS. This feature
would change arith to a different type, but can't work, because it
would conflict with definitions of arith in both <em_arith.h> and
<flt_arith.h>.
- LLlex.c: Understand 'LL' or 'll' suffix. Cut size of constant when
it overflows writh, not only when it overflows the target machine's
types. (This cut might not be necessary, because we might cut it
again later.) When picking signed long or unsigned long, check the
target's long type, not the compiler's arith type; the old check
for `val >= 0` was broken where sizeof(arith) > 4.
- LLlex.h: Change struct token's tok_ival to writh, so it can hold a
long long literal.
- arith.c: Adjust to VL_VALUE being writh. Don't convert between
float and integer at compile-time if the integer might be too wide
for <flt_arith.h>. Add writh2str(), because writh might be too
wide for long2str().
- arith.h: Remove SPECIAL_ARITHMETICS. Declare full_mask[] here,
not in several *.c files. Declare writh2str().
- ch3.c, ch3bin.c, ch3mon.c, declarator.c, statement.g: Remove
obsolete casts. Adjust to VL_VALUE being writh.
- conversion.c, stab.c: Don't declare full_mask[].
- cstoper.c: Use writh for constant operations on VL_VALUE, and for
full_mask[].
- declar., field.c, ival.g: Add casts.
- dumpidf.c: Need to #include "parameters.h" before checking DEBUG.
Use writh2str, because "%ld" might not work.
- eval.c, eval.h: Add casts. Use writh when writing a wide constant
in EM.
- expr.c: Add and remove casts. In fill_int_expr(), make expression
from long long literal. In chk_cst_expr(), allow long long as
constant expression, so the compiler may accept `case 123LL:` in a
switch statement.
- expr.str: Change struct value's vl_value and struct expr's VL_VALUE
to writh, so an expression may have a long long value at compile
time.
- statement.g: Remove obsolete casts.
- switch.c, switch.str: Use writh in case entries for switch
statements, so `switch (ll) {...}` with long long ll works.
- tokenname.c: Add ULNGLNG so LLlex.c can use it for literals.
+ Addition of function prototypes and include files.
+ Change function definitions to ANSI C style.
+ Initial support for CMake
+ Scripts to generate compiler header is now sed based.
Edit build.lua for programs losing their private assert.h, so they
depend on a list of .h files excluding assert.h.
Remove modules/src/assert; it would be a dependency of cpp.ansi but we
didn't build it, so cpp.ansi uses the libc assert.
I hope that libc <assert.h> can better report failed assertions. Some
old "assert.h" files didn't report the expression. Some reported a
literal "x", because traditional C expanded the macro parameter x in
"x", but ANSI C89 doesn't expand macro parameters in string literals.
- hex numbers and floating point numbers were wrong
- grammar was wrong; did not accept correct ANSI C
- prototype updates did not work
- float parameters to routines without prototype were not upgraded to double
- the dot operator no longer requires lvalue as left-hand-side
