Martin Storsjö c06aca2432 Build libunwind before libcxxabi 
This is the correct layering/ordering.

This requies setting forcing CXX_SUPPORTS_CXX11=TRUE in cmake,
since it tries linking to see whether the C++ environment works,
but we haven't built libcxx yet.

Manually add the libcxx include directory to the include path
(since libunwind does use some C++ headers but doesn't require
linking to C++ libraries).

Martin Storsjö 0f0863b010 Define the list of architectures to build for in a variable 
This simplifies reducing the build to fewer architectures
(e.g. to speed up testing).

Martin Storsjö 03f1fd6c65 Use dwarf exceptions on armv7 and aarch64 
Dwarf is also the default in clang on i686, but libunwind currently
has an issue relating to unwinding dwarf exceptions on i686 on
windows (and less easily reproducible on other platforms),
see https://reviews.llvm.org/D38680.

This enables exceptions on aarch64, where they previously were
avoided/disabled.

When linking to a statically linked libunwind with support for
dwarf, one (currently) has to link in -lpsapi.

Martin Storsjö 1ee6d578b2 Don't manually mkdir the prefix directory 
Doing "make install" will make the directory implicitly anyway.

Martin Storsjö e98f0ac6cc Update llvm/clang/lld/mingw-w64/compiler-rt/libunwind to the latest versions 2017-11-20 14:54:52 +02:00

Martin Storsjö 69348a747d Build libcxx with threads 
This is required for e.g. C++ atomics.

This requires all code including libcxx headers to be built with
_WIN32_WINNT >= 0x600.

Martin Storsjö c34e06a3b4 Update mingw-w64 to a version allowing setting the default win32 version 2017-11-04 22:35:46 +02:00
Martin Storsjö d8261ac0fb Don't rely on AR/RANLIB env variables during the toolchain build 
Instead manually specify the tools to be used in all of these steps.

Martin Storsjö 968e574272 Don't set LD=lld 
Using lld directly like that doesn't work, and will mess up building
some projects that use autotools.
 2017-11-03 16:43:55 +02:00
Martin Storsjö 6eba8f7259 Update all components to their latest version 
This includes fixes for (among other) issues with dllexport of
function names starting with an underscore (including C++ symbols)
in lld.

Martin Storsjö f849f47859 Define LIBCXX_USE_COMPILER_RT while building libcxx 
This makes a lot more libcxx cmake configure tests work as intended,
which makes a lot more -W* options added, resulting in much more build
warnings.
 2017-10-19 11:23:43 +03:00
Martin Storsjö a53599c175 Stop setting -D_LIB*_DISABLE_VISIBILITY_ANNOTATIONS while building user code 
This actually gets set by default by the installed config headers,
depending on how the libraries were configured.

Also, the -Xclang -flto-visibility-public-std workaround doesn't
seem to be necessary while building these test apps (but it might
potentially be necessary if building more complicated apps).

Martin Storsjö e8a4085954 Stop building libav as test application 
This works reliably and only adds build time when testing.
 2017-10-19 10:29:35 +03:00
Martin Storsjö 8596d83d1a Set the exceptions option properly for libcxx 
Apparently this built fine even with the flag set to on even though
it's intended to be disabled though.
 2017-10-18 16:57:17 +03:00
Martin Storsjö f8837d209c Update to the latest llvm/clang/lld 
These contain fixes relevant for arm64.
 2017-10-12 10:07:06 +03:00
Martin Storsjö 7730f5952e Enable threads when building libunwind 
The thread local SjLj context pointers are only flagged properly
as thread local when building with threads enabled.

Martin Storsjö 1c770a278a Update to the latest version of mingw-w64 2017-10-09 13:43:21 +03:00
Martin Storsjö 2260db1904 Build llvm with assertions 
This makes sure none of the tested codepaths do anything unexpected;
it's enabled by default in debug builds, but we still want an optimized
build.

Martin Storsjö 1f848ff6d4 Update mingw-w64, compiler-rt, libcxx, libcxxabi and libunwind to the latest versions 2017-10-04 09:34:24 +03:00
Martin Storsjö ed1d1497a7 Build libunwind, enable exceptions in libcxxabi and libcxx 
This requires manually enabling sjlj exceptions, since libunwind
doesn't support the other exception handling mechanisms on windows
(yet).

Don't enable exceptions on aarch64 yet, since no exception handling
mechanism is implemented for windows on aarch64 yet.
 2017-10-04 09:14:02 +03:00
Martin Storsjö 1767090a94 Update to the latest llvm/clang/lld 
This version of llvm has got working SjLj exception handling
on x86, x86_64 and arm.
 2017-10-04 08:16:47 +03:00
Martin Storsjö b1a39b7fa4 Drop an old workaround 
This probably isn't necessary when we now use the proper llvm-dlltool
instead of genlib.
 2017-09-25 16:50:09 +03:00
Martin Storsjö d9347135b6 Update to the latest version of llvm/clang/lld 
This includes support for a few more mingw lld features.
 2017-09-13 10:31:33 +03:00
Martin Storsjö c571ff004e Update to the latest version of libcxx 
This version can do without the two patches we carried locally.
 2017-09-13 09:58:00 +03:00
Martin Storsjö 403cbade55 Update to the latest version of llvm/clang/lld

Martin Storsjö 1d0c75addf Update to the latest version of mingw-w64 
This version supports setjmp on arm and arm64.

Martin Storsjö 82dfb17318 Simplify the cmake configuration for llvm 
Most of these parameters were redundant, or doesn't serve any purpose
as far as I can see.

Martin Storsjö 0dba17c5bf Clean up some commented out parts 2017-09-08 11:24:26 +03:00
Martin Storsjö 4ec04722ef Update llvm/clang/lld/mingw-w64/libcxx to newer versions 
These versions contain fixes relevant to mingw/clang.

Do the svn rebase (only necessary for getting sensible llvm/clang
version numbers in clang --version) before checking out the specific
version, otherwise we always end up at the latest master version.

Martin Storsjö 2d5bf52883 Add || exit 1 for exiting loops immediately on failures 2017-08-31 13:37:15 +03:00
Martin Storsjö 961868b9f2 Update llvm/clang/lld/libcxx to the latest upstream versions 
llvm and clang have got new patches that are relevant for mingw
and arm64/win.

compiler-rt has changed things, so we can't ask it to build builtins
for i686 any longer, but need to request it for i386 instead - and
clang will expect it to be named i386 even though we're invoking it
with an i686 target.

This requires updating to the latest version of mingw-w64.
 2017-08-28 23:02:36 +03:00
Martin Storsjö 3fc98d9d8a Remove a leftover --depth=1 
That obviously doesn't work when wanting to check out a specific,
possibly older, revision.

Martin Storsjö 43906e77d6 Stop autoreconfiguring mingw-w64-crt 
We don't patch the makefiles at the moment.
 2017-08-25 14:16:53 +03:00
Martin Storsjö f672db193b Adjust cmake invocations for building compiler-rt 
This fixes cross-building for i686.

Martin Storsjö 3e1dfb2e79 Initialize the llvm/clang checkouts with git-svn 
This produces more sensible version numbers in the clang --version
output.
