Martin Storsjö b08f71e33d Update to the latest version of llvm/lld/compiler-rt 
This adds support for stack probing on arm64 and fixes
some issues with data symbols in DLLs on arm.
 2017-12-20 11:21:32 +02:00
Martin Storsjö 4a4a9fd0e3 Update to the latest version of mingw-w64 
This fixes a number of issues in ucrtbase, and makes the headers
compatible with widl again.

Martin Storsjö a9651f45f3 Do git svn rebase on lld as well 
The version number is printed in "ld.lld -v".

Martin Storsjö 68b8f014a0 Skip unnecessary braces for consistency 2017-12-15 12:07:53 +02:00
Martin Storsjö 2a0172efd4 Provide the clang wrapper as a symlink to the script instead of duplicating the script 2017-12-15 12:07:23 +02:00
Martin Storsjö a52d13b639 Update to the latest versions of llvm/mingw/lld 
The previous pinned version of llvm miscompiled some files for
ARM, fixed in SVN r319652.

Martin Storsjö 0ce2f55a89 Use native TLS on all architectures except aarch64 
Update mingw-w64 to the latest version, where native TLS works
with LLVM/LLD.
 2017-12-04 14:31:42 +02:00
Martin Storsjö edcf22bec4 Build a test program for testing TLS support 2017-12-04 13:53:44 +02:00
Martin Storsjö 634ae81950 Pass -femulated-tls to the compiler by default 
The MinGW CRT wrapping has a few minor issues that makes native
TLS fail at the moment.

LLVM doesn't support native TLS on windows/aarch64, but emulated
TLS is supported now.
 2017-12-04 13:49:32 +02:00
Martin Storsjö 9e070797a3 Update llvm/clang/lld and mingw-w64 to the latest version 
This allows using -femulated-tls on arm and aarch64, and adds a few
more import libraries for aarch64.
 2017-12-04 11:15:41 +02:00
Martin Storsjö 44ebb5949e Remove superfluous mkdir statements 2017-12-02 23:52:10 +02:00
Martin Storsjö 68ba1b90d8 Update to the latest version of mingw-w64 
This version fixes running constructors with a non-default priority,
when built with clang/lld.
 2017-11-30 10:04:10 +02:00
Martin Storsjö a3324bfb07 Use dwarf exceptions on x86_64 as well 
SEH is the default on x86_64, but libcxxabi lacks support for it.
 2017-11-30 09:04:32 +02:00
Martin Storsjö bceb7bc463 Update to the latest versions of llvm/clang/lld 
This includes support for a -fdwarf-exceptions flag in clang,
allowing to choose that exception handling model on architectures
where it isn't the default.
 2017-11-30 09:01:06 +02:00
Martin Storsjö 26bba774fe Merge libpsapi.a into libunwind.a 
This avoids having to manually add -lpsapi when linking in libc++.a.

This requires using a new script to merge libraries using ar -M
with a small MRI script.

The script merge_archives.py in libcxx does the merge by manually
extracting all object files and creating a new archive out of them.
The import libraries created by LLVM have more than one object file
with the same file name (just like MSVC tools do), so extracting
them doesn't work as intended - but merging using a MRI script works.
 2017-11-28 22:56:42 +02:00
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).
 2017-11-28 22:56:42 +02:00
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).
 2017-11-28 22:19:44 +02:00
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.
 2017-11-20 14:58:44 +02:00
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 18904a3cda Make indentation more consistent in the dockerfile 2017-11-04 22:46:14 +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.
 2017-11-04 22:35:46 +02:00
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.
 2017-11-03 16:45:07 +02:00
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.
 2017-10-24 12:06:11 +03:00
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).
 2017-10-19 11:10:43 +03:00
Martin Storsjö fe547b6317 Get rid of trailing whitespace 2017-10-19 10:49:35 +03:00
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.
 2017-10-09 22:58:11 +03:00
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.
 2017-10-07 00:12:59 +03:00
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.
