Various dtoa.c cleanups. 1. Despagghetify _Py_dg_strtod parsing code
and exit points. 2. Simplify bigcomp comparison loop. 3. Don't set
ERANGE on _Py_dg_strtod underflow (it was set inconsistently anyway).
4. Remove unused dsign field from BCinfo struct.

Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the
private memory allocation scheme in dtoa.c, along with a piece of code
that caches powers of 5 for future use. This makes it easier to
detect dtoa.c memory leaks with Valgrind or similar tools.

Patch by Stefan Krah.

into the Python core
- on platforms where we can use Gay's code (almost
all!), repr(float) is based on the shortest
sequence of decimal digits that rounds correctly.
- add sys.float_repr_style attribute to indicate
whether we're using Gay's code or not
- add autoconf magic to detect and enable SSE2
instructions on x86/gcc
- slight change to repr and str: repr switches
to exponential notation at 1e16 instead of
1e17, str switches at 1e11 instead of 1e12]]> Mark Dickinson <dickinsm@gmail.com> Thu, 16 Apr 2009 19:52:09 +0000
