Tom Stellard e6ba81dae9 Add patch level to llvm version in CMake and Autoconf
The shared library generated by autoconf will now be called
libLLVM-$(VERSION_MAJOR).$(VERSION_MINOR).$(VERSION_PATCH)$(VERSION_SUFFIX).so
and a symlink named
libLLVM-$(VERSION_MAJOR).$(VERSION_MINOR)$(VERSION_SUFFIX).so will
also be created in the install directory.

Chandler Carruth bbae512cd2 [C++11] Replace autoconf --enable-cxx11 with --enable-cxx1y. The
baseline is now C++11, and we unconditionally add -std=c++11 to the
flags.

This has the dim potential to break some non-GNU-compatible compiler (in
terms of -std flags) using the makefiles, but those makefiles are
littered with GNU-style compile flags so it would be very surprising to
me for it to actually happen in practice. As always, do let me know if
there is a toolchain you're using where this doesn't work, and I'll be
watching the bots.

Chandler Carruth f92205336d [C++11] Switch autoconf and make to use C++11 by default. Now both build
systems have the default as C++11, but retain the ability to build with
C++98.

Again, please restrain your enthusiasm a bit in case this needs to be
reverted. =]

Todd Fiala 4ccfe392ed Fix configure to find arc4random via header files.
ISSUE:

On Ubuntu 12.04 LTS, arc4random is provided by libbsd.so, which is a
transitive dependency of libedit. If a system had libedit on it that
was implemented in terms of libbsd.so, then the arc4random test,
previously implemented as a linker test, would succeed with -ledit.
However, on Ubuntu this would also require a #include <bsd/stdlib.h>.
This caused a build breakage on configure-based Ubuntu 12.04 with
libedit installed.

FIX:

This fix changes configure to test for arc4random by searching for it
in the standard header files. On Ubuntu 12.04, this test now properly
fails to find arc4random as it is not defined in the default header
locations. It also tweaks the #define names to match the output of the
header check command, which is slightly different than the linker
function check #defines.

I tested the following scenarios:

(1) Ubuntu 12.04 without the libedit package [did not find arc4random,
as expected]

(2) Ubuntu 12.04 with libedit package [properly did not find
arc4random, as expected]

(3) Ubuntu 12.04 with most recent libedit, custom built, and not
dependent on libbsd.so [properly did not find arc4random, as
expected].

(4) FreeBSD 10.0B1 [properly found arc4random, as expected]

Peter Collingbourne c7d437c118 Introduce line editor library.
This library will be used by clang-query. I can imagine LLDB becoming another
client of this library, so I think LLVM is a sensible place for it to live.
It wraps libedit, and adds tab completion support.

The code is loosely based on the line editor bits in LLDB, with a few
improvements:

 - Polymorphism for retrieving the list of tab completions, based on
   the concept pattern from the new pass manager.

 - Tab completion doesn't corrupt terminal output if the input covers
   multiple lines. Unfortunately this can only be done in a truly horrible
   way, as far as I can tell. But since the alternative is to implement our
   own line editor (which I don't think LLVM should be in the business of
   doing, at least for now) I think it may be acceptable.

 - Includes a fallback for the case where the user doesn't have libedit
   installed.

Note that this uses C stdio, mainly because libedit also uses C stdio.

Chandler Carruth eba44ea533 Use a heavier hammer when --enable-libcpp is passed to bypass the tests
which catch buggy versions of libstdc++. While libc++ would pass them,
we don't actually update the state in the configure script to use libc++
when we pass --enable-libcpp, the logic for that is in the
Makefiles. So just completely skip the library test when that configure
flag is passed.

Hopefully this will be enough to fix the darwin bots at last, and thanks
to Duncan Smith for getting things set up so I can watch the bots myself
on lab.llvm.org and see any failures!

Chandler Carruth 7206eaefef Sink the autoconf check for sufficiently modern host toolchain below the
enable flag that selects the C++ standard library to use with the host
toolchain. Otherwise we end up testing the wrong config.

I'm not really happy about this placement, but its pragmatic and should
unblock the Apple builders.

Chandler Carruth f8c6ccf85d Add a check to configure that the libstdc++ selected by Clang isn't
libstdc++v4.6. This is quite hard to test directly, so we test for it by
checking a known missing feature in that version that was added in v4.7.

This should prevent users from upgrading Clang but not GCC and hosting
with a too-old GCC's libstdc++ and getting strange and hard to debug
errors when we switch to C++11 by default.

Also, switch several of the macros I introduced to use AC_LANG_SOURCE
rather than AC_LANG_PROGRAM as we don't need configure's help writing
our main function (and we don't need such a function at all for most of
the tests).

Chandler Carruth 75a6545d0e Add checks to configure for sufficiently modern host compilers. This
requires Clang 3.1 or GCC 4.7. If the compiler isn't Clang or GCC, we
don't try to do any sanity checking, but this give us at least
a reasonable baseline of modern compilers.

Also, I'm not claiming that this is the best way to do compiler version
tests. I'm happy for anyone to suggest better ways of doing this test.

Daniel Dunbar eb6c708d92 [conf] Add config variable to disable crash related overrides.
- We do some nasty things w.r.t. installing or overriding signal handlers in
   order to improve our crash recovery support or interaction with crash
   reporting software, and those things are not necessarily appropriate when
   LLVM is being linked into a client application that has its own ideas about
   how to do things. This gives those clients a way to disable that handling at
   build time.

 - Currently, the code this guards is all Apple specific, but other platforms
   might have the same concerns so I went for a more generic configure
   name. Someone who is more familiar with library embedding on Windows can
   handle choosing which of the Windows/Signals.inc behaviors might make sense
   to go under this flag.

 - This also fixes the proper autoconf'ing of ENABLE_BACKTRACES. The code
   expects it to be undefined when disabled, but the autoconf check was just
   defining it to 0.

llvm-svn: 188606
2013-08-17 11:06:00 +00:00
Chandler Carruth 912198585d Remove all checking for the various terminfo headers (term.h and
curses.h). Finding these headers is next to impossible. For example, on
Debian systems libtinfo-dev provides the terminfo reading library we
want, but *not* term.h. For the header, you have to use libncurses-dev.
And libncursesw-dev provides a *different* term.h in a different
location!

These headers aren't worth it. We want two functions the signatures of
which are clearly spec'ed in sys-v and other documentation. Just declare
them ourselves and call them. This should fix some debian builders and
provide better support for "minimal" debian systems that do want color
autodetection.

2013-08-12 10:40:11 +00:00
Chandler Carruth f11f1e43de Target a minimal terminfo library rather than necessarily a full curses
library for color support detection. This still will use a curses
library if that is all we have available on the system. This change
tries to use a smaller subset of the curses library, specifically the
subset that is on some systems split off into a separate library. For
example, if you install ncurses configured --with-tinfo, a 'libtinfo' is
install that provides just the terminfo querying functionality. That
library is now used instead of curses when it is available.

This happens to fix a build error on systems with that library because
when we tried to link ncurses into the binary, we didn't pull tinfo in
as well. =]

It should also provide an easy path for supporting the NetBSD
libterminfo library, but as I don't have access to a NetBSD system I'm
leaving adding that support to those folks.

llvm-svn: 188160
2013-08-12 09:49:17 +00:00
Chandler Carruth cad7e5e0b4 Add support for linking against a curses library when available and
using it to detect whether or not a terminal supports colors. This
replaces a particularly egregious hack that merely compared the TERM
environment variable to "dumb". That doesn't really translate to
a reasonable experience for users that have actually ensured their
terminal's capabilities are accurately reflected.

This makes testing a terminal for color support somewhat more expensive,
but it is called very rarely anyways. The important fast path when the
output is being piped somewhere is already in place.

The global lock may seem excessive, but the spec for calling into curses
is *terrible*. The whole library is terrible, and I spent quite a bit of
time looking for a better way of doing this before convincing myself
that this was the fundamentally correct way to behave. The damage of the
curses library is very narrowly confined, and we continue to use raw
escape codes for actually manipulating the colors which is a much sane
system than directly using curses here (IMO).

If this causes trouble for folks, please let me know. I've tested it on
Linux and will watch the bots carefully. I've also worked to account for
the variances of curses interfaces that I could finde documentation for,
but that may not have been sufficient.

Sylvestre Ledru 93a491bbf4 The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.
This kind of simplification is sometimes useful, but in general it's not correct. 

As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the
build definitions used for FreeBSD, whereas for userland-related issues we want to
match the definitions used for other systems with Glibc.

The current modification adjusts the build system so that they can be distinguished,
and explicitly adds GNU/kFreeBSD to the build checks in which it belongs.

Fixes bug #16444.
