Martin Storsjö 7c891a036d Don't point libunwind to the libcxx include directory 
This is no longer necessary.
 2019-01-30 09:19:47 +02:00
Martin Storsjö 2ccb0d5975 Update libunwind to the latest version 
This version drops the dependency on standard C++ library headers.
 2019-01-30 09:19:38 +02:00
Martin Storsjö 6cab2bca42 Update libunwind to the latest version 
This version fixes restoring of float registers for armv7, when using
dwarf exceptions (which we use by default).
 2019-01-29 11:01:10 +02:00
Martin Storsjö 68aa79a99b Create the prefixless objcopy/strip tools from an executable 
This is necessary since 62b208aee2.
 2019-01-24 13:46:08 +02:00
Martin Storsjö 5f56f7694b Display the output filename after packaging the cross built toolchain 2019-01-24 13:25:16 +02:00
Martin Storsjö 56506a5c6e Avoid warnings when building libcxxabi due to redefining _LIBCPP_BUILDING_LIBRARY 
Some libcxxabi source files define _LIBCPP_BUILDING_LIBRARY themselves.

A "#define FOO" in a file defines it to "", while "-DFOO" on the command
line defines it to "1". Define it on the command line using "-DFOO=" to
make it match the #define within the source files.
 2019-01-24 11:12:17 +02:00
Martin Storsjö a0d10c51cc Build libunwind with -Wno-dll-attribute-on-redeclaration 
libunwind doesn't have the dllexport attributes on the original
declarations of functions, and clang normally warns about this.
 2019-01-24 11:12:09 +02:00
Martin Storsjö 371f002680 Revert "Suppress compiler warnings in libunwind/libcxxabi if llvm cmake files are unavailable" 
This reverts commit 92f301f775.

With the latest versions of libunwind and libcxxabi, the -w option
for suppressing compiler warnings isn't added any longer when building
with the llvm cmake files available.
 2019-01-24 11:11:40 +02:00
Martin Storsjö bc4dde7cd1 Update libunwind and libcxxabi to the latest versions 
These versions no longer disable warnings when llvm cmake files
are available, and have got a lot of warnings silenced within the
code.
 2019-01-24 11:11:36 +02:00
Martin Storsjö 62b208aee2 Use llvm-objcopy/llvm-strip instead of a shell script wrapper and binutils 2019-01-24 10:58:20 +02:00
Martin Storsjö 78bade5cf1 Build and install llvm-objcopy and llvm-strip 2019-01-24 10:58:20 +02:00
Martin Storsjö c013ab7548 Update llvm/clang/lld to the latest version 
In this version, llvm-objcopy has gained support for operating on
COFF object files and executables.
 2019-01-24 10:58:20 +02:00
Martin Storsjö add8d6ee31 Update mingw-w64 to the latest version 
This fixes issues with the _xgetbv builtin in latest trunk versions
of clang.
 2019-01-24 10:58:20 +02:00
Martin Storsjö da00a0662e Update libunwind to the latest version 
This version makes libunwind actually make the SjLj context properly
thread local.
 2019-01-18 22:39:26 +02:00
Martin Storsjö f43d7825e5 Remove the new OptRemarks.dll when stripping the llvm installation 2019-01-04 01:30:26 +02:00
Martin Storsjö 6d9eb8296f Update llvm/clang/lld 
This implements the .arch_extension directive for aarch64, and fixes a
regression in the C++ ABI in the previous clang update.
 2019-01-03 09:04:43 +02:00
Martin Storsjö 5be98a5cd6 Ignore *.tar.xz and *.zip for docker builds 2019-01-03 09:04:43 +02:00
Martin Storsjö b9eb66bc1f Set LIBCXX_INCLUDE_TESTS=FALSE when building libcxx 
The DLL build fails since we stopped setting LIBCXX_ABI_UNSTABLE=TRUE,
if the tests are enabled (which they are if building against a
non-stripped llvm installation).
 2018-12-21 09:42:38 +02:00
Martin Storsjö 585c767ee4 Use llvm-ar with the flag 'L' instead of a helper MRI script for merging archives 2018-12-20 12:11:10 +02:00
Martin Storsjö 52fc6c5c06 Update libunwind to the latest version 
This version supports SEH unwinding on aarch64.
 2018-12-20 12:10:15 +02:00
Martin Storsjö 5004db0de6 Update mingw-w64 to the latest version 
This fixes symbol availability of __C_specific_handler for
use of SEH on arm64.
 2018-12-20 12:10:15 +02:00
Martin Storsjö 04beed38bc Update llvm/clang/lld 
This version supports SEH for arm64, fixes certain cases of dllexport
of C++ classes defined entirely in headers (fixing building Qt in
debug mode), and fixes a compiler bug (regression since the end of
August 2018) when compiling glslang (as part of VLC) for armv7.
 2018-12-20 12:10:15 +02:00
Martin Storsjö 837fee3ce1 Clarify the output of the exception-locale test 2018-12-12 00:07:50 +02:00
Martin Storsjö 1228a03be4 Update libunwind to the latest version, fixing SEH exceptions in certain cases 2018-12-11 13:35:56 +02:00
Martin Storsjö 7e0dbe79bf Stop building libcxx with LIBCXX_ABI_UNSTABLE=TRUE 
This didn't seem to actually be necessary, not even in the initial
commit adding support for building a DLL of libcxx. It might have
been necessary at some earlier point while working on building a DLL.
 2018-12-06 00:49:25 +02:00
Martin Storsjö 7a86e4ce73 Define _LIBCPP_ABI_UNSTABLE manually when building libcxxabi 
This is set via a cmake option when building libcxx, but libcxxabi
uses the raw libcxx headers from its include directory before they
are installed.

This fixes cases of inconsistent classes seen while compiling libcxxabi
and libcxx. With potential future patches to clang to adjust how
classes are exported with dllexport, this change is needed to avoid
conflicts.
 2018-12-05 13:47:48 +02:00
Martin Storsjö 4d861b67b5 Don't move clang.exe to clang-<major>.exe if clang-<major>.exe already exists 2018-11-30 12:03:09 +02:00
Martin Storsjö 11a83711ad Check that clang.exe exists before moving it to clang-<major>.exe 2018-11-30 12:03:09 +02:00
Martin Storsjö 32668f336b Keep clang.exe around if we won't be replacing it with an unprefixed wrapper 2018-11-30 12:03:09 +02:00
Martin Storsjö e45e9ab98e Update compiler-rt to a newer version 
This fixes building sanitizers natively on windows/msys.
 2018-11-30 12:03:09 +02:00
Martin Storsjö 1f838437ca Automatically set EXEEXT in build-mingw-w64.sh and strip-llvm.sh 2018-11-30 12:03:09 +02:00
Martin Storsjö 9e7a6e0afb Convert msys style paths to windows style in merge-archives.sh 2018-11-30 12:03:09 +02:00
Martin Storsjö fdd0a116ae Try to set "MSYS Makefiles" as cmake generator in mingw environments 2018-11-30 12:03:09 +02:00
Martin Storsjö f9811f258e Set CMAKE_GENERATOR to the intended generator only, add the -G separately 2018-11-30 12:03:09 +02:00
Martin Storsjö d294d17053 Create the prefix/triplet/bin directory before installing DLLs in build-libcxx.sh 
If the triplet directory is wiped and only the build-mingw-w64.sh
step is rerun, the bin subdirectory would be missing, ending up
with a file named "bin", which actually was the libc++ DLL.
 2018-11-30 11:37:00 +02:00
Martin Storsjö 53db1c3a4c Resolve $PREFIX to an absolute path at the start of shell scripts 
This fixes building/installing into a relative path.
 2018-11-23 13:51:05 +02:00
Martin Storsjö ecdbfaacc3 Only apply .gitignore ignore rules at the top level 2018-11-20 22:51:35 +02:00
Martin Storsjö ae2a98efba windres: Ignore the --use-temp-file option 
This option seems to be used occasionally by projects to work around
various issues with popen in GNU windres.

Our windres wrapper always uses a temp file for the preprocessing
output, so for us the option is a no-op.
 2018-11-13 00:35:53 +02:00
Martin Storsjö 99e2fefc9d Use nproc and sysctl -n hw.cpu for default initializing CORES 
This avoids having to pass --build-arg CORES=n when building the
docker images.
 2018-11-09 22:20:34 +02:00
Martin Storsjö 9367988be7 Mention the fact that binutils can't use the generated import libraries 2018-11-03 14:26:21 +02:00
Martin Storsjö 8002486c84 clang-target-wrapper: Filter the output from "clang -v" on windows 
Convert paths with backslashes to forward slashes.

libtool tries to parse this output in order to find object files and
libraries that always should be linked in, but libtool can't handle
paths with backslashes (and quotes) which clang currently outputs.

This is a quick and ugly workaround until clang can be made to
output paths with forward slashes on windows, see
https://reviews.llvm.org/D53066 for progress on that matter.
 2018-11-02 12:31:41 +02:00
Martin Storsjö 643d9c1645 windres: Fix handling of -D/-U options with a space between the option and the name of the define 2018-10-19 09:23:30 +03:00
Martin Storsjö af069a9c29 Update to the latest version of mingw-w64 
This fixes the _isdigit_l function for UCRT, fixing iostream formatting
of numbers in certain cases, in cases e.g. like this:
    double test = 1.0 / 3.0;
    std::cout << test << std::endl;
 2018-10-19 09:15:43 +03:00
Martin Storsjö a999e54760 Mention prebuilt binaries in the readme 2018-10-17 23:34:13 +03:00
Martin Storsjö f09fc9d618 Add a script for packaging a release 2018-10-17 23:19:43 +03:00
Martin Storsjö fc88912646 Mention ubsan in the readme 2018-10-17 22:45:54 +03:00
Martin Storsjö c9817eca35 Add a testcase for ubsan 2018-10-17 22:45:54 +03:00
Martin Storsjö 6ead0a46b3 Add a known issue about the fact that sanitizers only are supported on x86 2018-10-17 22:45:54 +03:00
Martin Storsjö c1fe94fcef Update compiler-rt to the latest version 
This fixes using ubsan with mingw targets.
 2018-10-17 22:45:54 +03:00
Martin Storsjö 2244b6cdfa Update llvm/clang/lld to a newer version 
This makes the help output from llvm-nm contain keywords that libtool
may look for, makes combined compilation and linking with -flto in
one command work, fixes a bug with alignment of locally imported
symbols on arm64, allows using linker directives for specifying
default libraries to link, and allows linking to undefined behaviour
sanitizer.
 2018-10-17 22:45:54 +03:00
Martin Storsjö f47a4009ac Add a separate dockerfile for crosscompiling the toolchain itself 2018-10-17 22:45:54 +03:00
Martin Storsjö f5008d5380 Merge build-mingw-w64-widl.sh back into build-mingw-w64.sh 
This allows checking out the mingw-w64 repo if it is missing, when
building widl.
 2018-10-17 22:45:54 +03:00
Martin Storsjö 14e7d650f1 Allow building llvm-tblgen/clang-tblgen/llvm-config if needed 2018-10-16 20:27:53 +03:00
Martin Storsjö 5390b58835 Consistently use "COPY .. ./" in Dockerfiles 
This avoids potential issues and confusion with cases where a plain "." as
target doesn't work.
 2018-10-16 20:25:39 +03:00
Martin Storsjö e9d8d57ec6 Fix adding build-compiler-rt.sh after wiping the build dir 
With newer docker versions, "COPY foo .", when the workdir doesn't exist,
produces a plain file named as the workdir, breaking the rest of the build.
 2018-10-16 19:42:31 +03:00
Martin Storsjö 3c6e1fe8bc Make a shell script case more compact 2018-10-13 23:57:41 +03:00
Martin Storsjö 73bd1bc62c Provide wrappers named cc/c99/c11/c++ as well 2018-10-10 23:33:19 +03:00
Martin Storsjö 3d1b15b01e Make widl default to prefix/include instead of prefix/target/include, for windows toolchains 
In these setups, we already install headers into prefix/include, in
order to save diskspace.
 2018-10-10 23:33:19 +03:00
Martin Storsjö f16867dd20 Update mingw-w64 to the latest version 
This version allows overriding the default include directory used
by widl.
 2018-10-10 23:33:19 +03:00
Martin Storsjö 8bfc9a18c6 Error out early if trying to compile ada 
If we try to do that, clang would end up calling <triplet>-gcc with the
same arguments. In our setup, this recursively ends up calling clang again,
ending up with infinite recursion.
 2018-10-10 23:33:19 +03:00
Martin Storsjö 7bca89b53f Adjust clang-target-wrapper.c to closer match the new windres wrapper 2018-10-10 23:33:19 +03:00
Martin Storsjö b611bc1904 Convert the windres wrapper from shell script to C 
This allow running windres on windows without a surrounding posix shell.
 2018-10-10 23:33:19 +03:00
Martin Storsjö 9069c627a9 Install unprefixed tools when cross compiling the toolchain 2018-10-10 23:33:19 +03:00
Martin Storsjö b5deb9fc1f Set a default target in wrapper scripts and executables 2018-10-10 23:33:19 +03:00
Martin Storsjö 1bc3d75a41 For cross-built toolchains, rename the clang executable to clang-$MAJOR.exe 2018-10-10 23:33:19 +03:00
Martin Storsjö fb26be33a1 Correct the escaping of arguments passed through on windows 2018-10-10 23:33:18 +03:00
Martin Storsjö b9543f23b9 Mention the lack of llvm-objcopy for COFF as a known issue in the readme 2018-10-09 11:40:26 +03:00
Martin Storsjö 2a3cdc9115 Update the description of the project's status 
The level of maturity is generally quite a bit higher now than when
this initially was written.
 2018-10-09 11:40:03 +03:00
Martin Storsjö a914746ab2 Remove the mention of other similar projects 
The mentioned differences aren't quite as pronounced any longer.
 2018-10-09 11:35:16 +03:00
Martin Storsjö 945845fba2 Make a helper function static in clang-target-wrapper.c 2018-10-08 14:15:25 +03:00
Martin Storsjö 818766d3d4 Use posix shell variable expansion substitution instead of subshells with sed 2018-10-08 14:13:42 +03:00
Martin Storsjö 0ec597b1bb Remove inconsistently used braces 
Using braces here is fine in itself, but we write most similar cases
without braces, so change it for consistency.
 2018-10-08 14:12:55 +03:00
Martin Storsjö 89c91ecaae windres: Print help and version texts to stdout 
meson checks the output from --version, and expects to see it on stdout.
 2018-10-08 14:12:55 +03:00
Martin Storsjö b1b6c0ba6f windres: Minor cleanups 
Make indentation consistent, define a variable used in printing errors,
remove an unused helper function.
 2018-10-08 14:12:54 +03:00
Martin Storsjö 03b99b5144 Do one in-bounds write in clean runs of stacksmash.c 2018-10-07 21:00:30 +03:00
Martin Storsjö 461f889187 Update llvm/clang/lld to the latest version 
This avoids warnings about both main and wmain being present when linking,
warnings that appeared in the previous update.
 2018-10-06 07:44:33 +03:00
Martin Storsjö 99b6407196 Quote arguments in clang-target-wrapper.c 
We quote each passed through argument, and escape quote chars in them.

For cases when the passed through argument ends with a backslash, this
fails though, since whatever is unescaping it doesn't seem to handle
double backslashes for escaping backslashes themselves.
 2018-10-05 12:46:11 +03:00
Martin Storsjö 22b5681765 Add $EXEEXT as suffix for the ar/ranlib/nm/strings symlinks 2018-10-05 12:46:10 +03:00
Martin Storsjö 10210478ee Update llvm/clang/lld to the latest version 
This fixes cases where llvm built without assertions can hang when
assembling a file that references _GLOBAL_OFFSET_TABLE_ for windows
(which is unsupported; previously this used llvm_unreachable making
it undefined what happens if that really is hit).
 2018-10-05 09:07:41 +03:00
Martin Storsjö a62ee10c2d Build clang-target-wrapper.c with -municode for windows 2018-10-03 23:06:22 +03:00
Martin Storsjö ad47efba70 Implement clang-target-wrapper as an executable for windows 
This allows non-msys build systems to use the triplet prefixed
compiler frontends on windows.

Keep the old shell script version as well, for easier hackability
on unix platforms.
 2018-10-03 22:48:36 +03:00
Martin Storsjö 9f3a4a25f2 Support wrappers named <triplet>-c++ in clang-target-wrapper.sh as well 
We currently don't install any such wrapper, but one might want to.
 2018-10-02 23:38:19 +03:00
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.
 2018-10-02 21:34:54 +03:00
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.
 2018-10-02 21:34:54 +03:00
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.
 2018-10-02 21:34:54 +03:00
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
