Martin Storsjö fb5c95589c Restructure clang-target-wrapper.sh to set one flag per line 2018-10-02 23:38:19 +03:00
Martin Storsjö 7f98eea889 Mention prebuilt docker images from Docker Hub 2018-10-02 21:34:54 +03:00
Martin Storsjö 9db7f21bcb Make windres --version output the string "GNU windres" 
meson might start looking for this string soon, for identifying
the kind of resource compiler.

Martin Storsjö 773c0299c5 Add scripts for crosscompiling the toolchain using an already built native toolchain 2018-10-02 21:34:54 +03:00
Martin Storsjö 8f15532652 Clean up more for windows builds in strip-llvm.sh 
On windows, symlinks might be changed into regular copies, so we keep
as few extra symlinks as possible.
 2018-10-02 21:34:54 +03:00
Martin Storsjö 47392c5a90 Don't expect that all files exist in strip-llvm.sh 
If run multiple times, this removal would try to remove a file named
clang-*, which doesn't exist.
 2018-10-02 21:34:54 +03:00
Martin Storsjö 391c93d0d4 Allow strip-llvm.sh to run on files with a potential $EXEEXT suffix 2018-10-02 21:34:54 +03:00
Martin Storsjö 49103cf127 Strip the built widl by passing -Wl,-s to the linker, instead of INSTALL="install -s" 
When stripping via "install -s", install invokes the system's
strip tool, which might not support the cross target that we are
building for. This could also be handled by passing
--strip-program=<arch>-w64-mingw32-strip to install though.

Martin Storsjö fb4862b0d6 Split out building widl to a separate shell script 
When cross compiling a llvm-mingw toolchain, we need to build widl
for the intended host environment as well.
 2018-10-02 21:34:54 +03:00
Martin Storsjö 0c24f99adb Allow setting CC or HOST for install-wrappers.sh 
Also allow setting EXEEXT for the executable suffix.

Martin Storsjö bf2ede1537 Add support for crosscompiling llvm 2018-10-02 21:34:54 +03:00
Martin Storsjö 81864b3883 Disable asserts in llvm by default 
This gives a 25% speedup. As long as the llvm version has been
reasonably tested, this should hopefully be safe.
 2018-10-02 21:34:54 +03:00
Martin Storsjö 784c15f9b9 Allow passing --enable-shared/static to build-libcxx.sh 
These are the default already, but by allowing them as options, it becomes
easier to potentially change the default behaviour.
 2018-10-02 21:34:54 +03:00
Martin Storsjö d379cc8b21 Allow passing --enable-asserts to build-llvm.sh 
This is the default already, but by allowing this as an option, it becomes
easier to potentially change the default behaviour.
 2018-10-02 21:34:54 +03:00
Martin Storsjö 6bb0cfca58 Convert TOOLCHAIN_ARCHS from ENV to ARG 
This allows overriding it with --build-arg.
 2018-10-02 21:34:54 +03:00
Martin Storsjö 0a181a36a3 Use -n instead of != "" in build-llvm.sh 2018-10-02 21:34:54 +03:00
Martin Storsjö a7616d6d23 Add helpful printouts in stacksmash.c 2018-10-02 21:34:54 +03:00
Martin Storsjö a38e52fff5 Build address sanitizer 2018-10-02 14:53:53 +03:00
Martin Storsjö 6d7cef9e9e test: Rename ssp.c to stacksmash.c 2018-10-02 14:53:53 +03:00
Martin Storsjö cea63c570a Update llvm/clang/lld to the latest version 
This version allows clang to use address sanitizer for mingw,
adds support for linking against import libraries from GNU tools
and makes the linker provide the __CTOR_LIST__ symbol for better
compatibility with binutils based sysroots, and adds support for
thunks for armv7 (allowing linking armv7 binaries over 16 MB).
 2018-10-02 14:53:53 +03:00
Martin Storsjö e26ab372bf Update compiler-rt to the latest version 
This version supports building address sanitizer for mingw.
 2018-10-02 14:53:53 +03:00
Martin Storsjö 4d110b4508 Update mingw-w64 to the latest version 
This fixes a few headers as necessary for building asan, and
fixes cross compiling widl.
 2018-10-02 14:53:53 +03:00
Jacek Caban bbe4f90ae3 Set _LIBDIR_SUFFIX in build-libcxx.sh 
This fixes building libcxx on Gentoo.
 2018-10-02 14:53:53 +03:00
Martin Storsjö 47fca28422 Tweak the wording for the comment about exception issues with dwarf for i686 2018-10-01 14:44:32 +03:00
Martin Storsjö f0aa7c4c10 Revert "Use dwarf exceptions on i686 as well" 
This reverts commit ca43ab5ccd.

It was reported in https://github.com/mstorsjo/llvm-mingw/issues/8 that
the dwarf unwinding on i686 doesn't always work.

This commit adds a testcase for the case that didn't work previously.

Martin Storsjö ab1da59a48 Use a single COPY command in dockerfiles for both *.sh and *.c for wrappers 2018-09-14 09:38:44 +02:00
Martin Storsjö 5a70c3cb78 Extend the dll autoimport test to test references to a external variable with offset 2018-09-07 00:02:16 +03:00
Martin Storsjö c8ca4bddd6 Add known issues about the fact that the toolchain by default targets Vista or newer 2018-09-05 13:39:28 +03:00
Martin Storsjö 5386ff8e3d Reindent build-mingw-w64-libraries.sh 
This was left inconsistent after 3c1c81f321.
 2018-09-05 13:11:26 +03:00
Martin Storsjö a7c2d85bf7 Update the comment about --enable-auto-import in the ld wrapper 2018-09-05 13:08:37 +03:00
Martin Storsjö 28dc4e3589 Remove known issues about a shared libc++ and automatic data imports 2018-09-05 12:28:33 +03:00
Martin Storsjö 523892f626 Adjust run-tests.sh to pick up shared versions of libc++/libunwind/libssp 2018-09-05 12:28:33 +03:00
Martin Storsjö d3ec443f92 Build libssp as a DLL as well 
This matches how it is normally available in GCC.
 2018-09-05 12:28:33 +03:00
Martin Storsjö aa80a9ecbc Copy the built DLLs into the test output directories 2018-09-05 12:28:33 +03:00
Martin Storsjö 957c34372c Build libunwind and libcxx both as static and dynamic libraries 2018-09-05 12:28:33 +03:00
Martin Storsjö bc0cde364d Skip new/delete definitions in libcxxabi 
These are also provided by libcxx, and can conflict if trying to
link a shared library containing both libcxxabi and libcxx.
 2018-09-05 12:28:33 +03:00
Martin Storsjö 72c4128a68 Update libcxxabi and libcxx to the latest version 
These versions add missing function visibility to __gxx_personality_seh0
for libcxxabi, and fixes including a static libcxxabi in a shared libcxx.
 2018-09-05 12:28:33 +03:00
Martin Storsjö 37f8ba8516 Add tests for the autoimport feature 2018-09-05 12:21:46 +03:00
Martin Storsjö 5f12b33177 Update llvm/clang/lld to the latest version from today 
This adds support for automatically importing variables from dlls
without using the dllimport attribute.
 2018-09-05 11:55:12 +03:00
Martin Storsjö c0246e97db readme: Escape an asterisk 2018-09-05 11:55:12 +03:00
Martin Storsjö 470008f09c Factorize the building of test DLLs in the dockerfile 2018-09-05 11:53:46 +03:00
Martin Storsjö 09567cdc96 Build tlstest-lib.dll in the arch specific output subdirectory as well 
This was missed in 0448bd61.
 2018-09-05 11:52:57 +03:00
Martin Storsjö 5e295f5c62 Allow building llvm with asserts disabled 
Doing that speeds up the built clang by around 25% (which is rather
significant) and reduces the size of the clang executable by almost 30%.

But since the mingw target in clang/llvm is less mature and less widely
tested than other llvm targets, running with assertions allows catching
quite a few issues during build instead of ending up with potentially
broken code.

Martin Storsjö 6bff543bd9 Use libunwind's built-in SEH support instead of libgcc 2018-08-31 12:15:28 +03:00
Martin Storsjö cdd5409cad Update libunwind to the latest version 
This version has got built-in support for SEH exceptions for x86_64.
 2018-08-31 11:34:37 +03:00
Martin Storsjö 6edb1a60e9 Update to the latest version of mingw-w64 
This makes sure that exiting by calling _exit or ExitProcess doesn't
run global objects' destructors, which happened since starting to use
__cxa_atexit since 11e04f0466.
This fixes LLD built for windows with this toolchain.
