David Schultz 3b204b7d09 - %e conversions with precision 0 should not cause a decimal point to
be printed.
- Fix %f conversions where the number of significant digits is < expt.
  This would be a one-line change were it not for thousands separators.
  Noticed by tjr.
- Remove some unnecessary code in the parsing of precision specifiers.

David Schultz ebbad5ec5c Rework the floating point code in printf(). Significant changes:
- We used to round long double arguments to double.  Now we print
  them properly.

- Bugs involving '%F', corner cases of '#' and 'g' format
  specifiers, and the '.*' precision specifier have been
  fixed.

- Added support for the "'" specifier to print thousands' grouping
  characters in a locale-dependent manner.

- Implement the __vfprintf() side of hexadecimal floating point
  support.  All that is still needed is a routine to convert the
  mantissa to hex digits one nibble at a time in the style of ultoa().

David Schultz 92b93b37c0 Add __ldtoa(), a wrapper around gdtoa() to make it look like dtoa().
In support of this, add some MD macros to assist in converting long
doubles to the format expected by gdtoa().

David Schultz b936664e72 Add missing #include to unbreak previous commit. 2003-04-05 22:08:53 +00:00
David Schultz 38cac8f88b Correct some buffer sizes.
- __vfprintf()'s 'buf' has never been used for floating point, so
  don't define it in terms of (incorrect) constants describing
  floating point numbers.  The actual size needed depends on
  sizeof(uintmax_t) and locale details, so I slightly overestimated.

- We don't need a 308-character buffer to store the string "308".
  With long doubles and %a we need more than three characters, though.

David Schultz 6a66acb565 Replace our ancient dtoa/strtod implementation with the gdtoa
package, a more recent, generalized set of routines.  Among the
changes:
- Declare strtof() and strtold() in stdlib.h.
- Add glue to libc to support these routines for all kinds
  of ``long double''.
- Update printf() to reflect the fact that dtoa works slightly
  differently now.

As soon as I see that nothing has blown up, I will kill
src/lib/libc/stdlib/strtod.c.  Soon printf() will be able
to use the new routines to output long doubles without loss
of precision, but numerous bugs in the existing code must
be addressed first.

Marcel Moolenaar cafd6dbd76 Fix threaded applications on ia64 that are linked dynamicly. We did
not save (restore) the global pointer (GP) in the jmpbuf in setjmp
(longjmp) because it's not needed in general. GP is considered a
scratch register at callsites and hence is always restored after a
call (when it's possible that the call resolves to a symbol in a
different loadmodule; otherwise GP does not have to be saved and
restored at all), including calls to setjmp/longjmp. There's just
one problem with this now that we use setjmp/longjmp for context
switching: A new context must have GP defined properly for the
thread's entry point. This means that we need to put GP in the
jmpbuf and consequently that we have to restore is in longjmp.
This automaticly requires us to save it as well.

When setjmp/longjmp isn't used for context switching, this can be
reverted again.
