Python/dtoa.c is not compiled correctly with clang 4.0 and
optimization level -O2 or higher, because of an aliasing issue on
the double/ULong[2] union.
LLVM bug report:
https://bugs.llvm.org//show_bug.cgi?id=31928
The presence of the ``--enable-optimizations`` flag is indicated by the
value of ``$enableval``, but the configure script was checking ``$withval``,
resulting in the ``--enable-optimizations`` flag being effectively ignored.
* Fix `make tags` warnings
`make tags` target tries to find C sources and headers in "Grammar" and
"Mac" folders and generates these warnings:
ctags: Warning: cannot open source file "Grammar/*.[ch]" : No such file or directory
ctags: Warning: cannot open source file "Mac/*.[ch]" : No such file or directory
This commit changes $SRCDIRS variable in configure.ac to remote these
directories. This variable is used only for tags generation.
Also, "configure" was regenerated with `autoreconf`.
* Fix `make tags` fail on non-default tag names
When ctags overrides default tags filename (e.g. `-f .tags`) `make tags`
is failed because it assumes to see default `tags` filename:
sort: cannot read: tags: No such file or directory
This commit explicitly specifies "tags" filename for tags generation.
Use --short form of git hash. Use output from "git describe" for tag.
Expected outputs:
1. previous hg
2. previous git
3. updated git

"dirty" means the working tree has uncommitted changes.
See "git help describe" for more info.
sys.version and the platform module python_build(),
python_branch(), and python_revision() functions now use
git information rather than hg when building from a repo.
Based on original patches by Brett Cannon and Steve Dower.
Issue #27659: use -Werror=implicit-function-declaration when possible (GCC and
Clang, but it depends on the compiler version).
Patch written by Chi Hsuan Yen.
Patch by Masayuki Yamamoto, reviewed and rebased by Erik Bray.
This is a first step on the long road toward resupporting Cygwin, which does
not provide siginfo_t.si_band.
Tested on macOS 10.11 dtrace, Ubuntu 16.04 SystemTap, and libbcc.
Largely based by an initial patch by Jesús Cea Avión, with some
influence from Dave Malcolm's SystemTap patch and Nikhil Benesch's
unification patch.
Things deliberately left out for simplicity:
- ustack helpers, I have no way of testing them at this point since
they are Solaris-specific
- PyFrameObject * in function__entry/function__return, this is
SystemTap-specific
- SPARC support
- dynamic tracing
- sys module dtrace facility introspection
All of those might be added later.
