bpo-35214: Add _Py_ prefix to MEMORY_SANITIZER def. (GH-10503)

2018-11-13T06:01:22+00:00

Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER.
Project based C Preprocessor namespacing at its finest. :P

bpo-35214: Initial clang MemorySanitizer support (GH-10479)

2018-11-12T20:07:14+00:00

Adds configure flags for msan and ubsan builds to make it easier to enable.
These also encode the detail that address sanitizer and memory sanitizer
should disable pymalloc.

Define MEMORY_SANITIZER when appropriate at build time and adds workarounds
to existing code to mark things as initialized where the sanitizer is otherwise unable to
determine that.  This lets our build succeed under the memory sanitizer.  not all tests
pass without sanitizer failures yet but we're in pretty good shape after this.

Issue 24366: Indent code (thanks to li4ick for reporting).

  Issue #7518:  Move substitute definitions of C99 math functions from
  pymath.c to Modules/_math.c.
........

The SSE2 detection and enabling could potentially cause

2009-04-18T20:17:52+00:00

problems for binary distributions of Python in situations
where the build machine has SSE2 but the target machine
does not.

Therefore, don't enable SSE2 instructions automatically on x86.

Issue #1580: use short float repr where possible.

2009-04-16T19:52:09+00:00

 - incorporate and adapt David Gay's dtoa and strtod
   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
