Martin Storsjö 0f9d9f1986 Check out llvm sources using the new llvm git monorepo 
This updates compiler-rt, libunwind, libcxxabi and libcxx to a newer
version, matching the compiler.

This will be the official, canonical repo in the future.

For the non-dev Dockerfile build, this means that all the llvm based
subprojects need to be built in one RUN to avoid storing the llvm
checkout in the docker layers.

Martin Storsjö d4a27dfd80 Stop manually setting CC/AR/RANLIB when building autotools projects 
Since we have triplet prefixed wrappers for all tools, and wrappers
named <triplet>-gcc/g++ as well, we don't need to manually provide
them.

Martin Storsjö da4562be1b Update to the latest version of mingw-w64 
This version includes fixes for a lot of c99 math functions.
 2019-08-01 22:30:32 +03:00
Martin Storsjö 315e1ab683 Install the needed packages in docker images with --no-install-recommends 
This avoids installing a few unneeded ones, but requires manually

Martin Storsjö 5f70dd1a1f Avoid errors when recreating an existing symlink on msys2 
In this environment, symlinks don't exist but are made as copies.
In such cases, the -n option to ln doesn't work for making this
a no-op.

Alternatively, we could append "|| true", which would print an
error but continue.
 2019-06-28 00:13:24 +03:00
Martin Storsjö c89799c996 Restore the original path before building widl 
When building on windows, the toolchain bin directory contains
prefixless wrappers named "gcc.exe" and "clang.exe", even though
the toolchain isn't functional yet at this stage. Restore the
original path before building widl.

A more complete solution might be to build widl first, before
adding the newly built toolchain to the path.
 2019-06-28 00:12:10 +03:00
Martin Storsjö f80d067176 Only make the prefixless widl symlink after compiling widl 
When building in msys2, symlinks are plain copies, and one can't
make the symlink in advance.
 2019-06-21 22:52:34 +03:00
Martin Storsjö 7edc154d50 wrappers: Unify comments about exception handling methods. 2019-05-28 15:29:08 +03:00
Martin Storsjö 4811c1f489 wrappers: Stop explicitly requesting SEH for AArch64 
It is the default exception handling model there now.
 2019-05-28 15:27:56 +03:00
Martin Storsjö 9d8339b48d Update mingw-w64 to the latest version 
This version fixes deadlocks in winpthreads condvars (in certain
use patterns), uses the _UCRT define to request and signal the
use of UCRT, fixes the UCRT _vsnwprintf function, uses the
CRT's setjmp/longjmp on AArch64 if SEH is in use, and makes the
UCRT set the app type to console properly for such apps.

Martin Storsjö 0d4861fdd3 readme: Document the new implicit pdb output file naming 2019-05-28 00:04:39 +03:00
Martin Storsjö 5623fd232c wrappers: Remove the ld wrapping of --help and -v 
The MinGW driver in lld now handle these flags, including the
libtool specific keywords.
 2019-05-28 00:04:39 +03:00
Martin Storsjö 0c7aac99ad Update llvm/clang/lld to the latest version 
This version adds support for a version of the -pdb option to the MinGW
frontend to lld that can work without a parameter, and implements --help
and -v for the same frontend.

Martin Storsjö d009355b91 build-llvm: Remove the now unnecessary BUILDTARGETS variable 2019-05-09 09:22:26 +03:00
Martin Storsjö 873243acc2 build-llvm: Use the built-in recursive cmake for building llvm-tblgen if necessary 
This requires setting a flag to use the system default compiler
for this, instead of the cross compiler.
 2019-05-09 09:22:26 +03:00
Martin Storsjö a8829aeebb build-libcxx: Remove cmake flag overrides that no longer are necessary 2019-05-09 09:22:26 +03:00
Martin Storsjö ca329c1cd4 run-tests: Check for the _UCRT define that latest upstream mingw-w64 defines 
The __MSVCRT_VERSION__ define has been changed and now is set to
0xE00 for UCRT, but the _UCRT define has been added.

Martin Storsjö 6223a35822 strip-llvm: Remove lld-link on windows 2019-05-06 11:05:25 +03:00
Martin Storsjö c3aeb78576 wrappers: Add a wrapper for running llvm binutils replacements 
This saves a lot of diskspace, when symlinks are turned into full
copies of the tools on windows, as the symlinks only point to a small
wrapper instead of to the full tool.
 2019-05-06 11:05:25 +03:00
Martin Storsjö 750ab50433 wrappers: Consistently quote all arguments when calling spawn or creating a command line 2019-05-06 11:04:53 +03:00

Martin Storsjö 66055dfe63 wrappers: Take the argv null terminator into account when checking for overflows 
When adding the terminator without incrementing arg and checking for
overflows with "arg > max_arg", we need to allocate space for one
extra element for the implicit terminator.
 2019-05-06 11:04:27 +03:00

The latter has now been renamed.
 2019-05-04 07:55:04 +03:00
Martin Storsjö 56ef08dadc Build libcxx without --export-all-symbols 
With the latest clang and libcxx, this workaround no longer is
necessary.

- Improvements in handling of dllexport of C++ template instantiations,
  allowing building libc++ into a DLL without using --export-all-symbols
- Proper separators in the output of clang --print-search-dirs on
  Windows
- A new flag --appcontainer to lld's mingw frontend
- Lld now has extra handling of crtend.o, fixing use of lld with gcc
  based mingw setups, when using dwarf exceptions
 2019-05-04 07:53:15 +03:00
Martin Storsjö 82324fcff5 run-tests: Build optimized versions of the exception handling tests 
Exception handling codegen can be greatly affected by optimization.

Martin Storsjö a484ddba04 Stop using --enable-secure-api with mingw-w64 headers 
This is on by default now, and the option is ignored (and produces
a warning).

This is fixed in the latest upstream version.
 2019-04-16 14:53:54 +03:00
Martin Storsjö 978a430069 Update mingw-w64 to a yet newer version 
This improves math functions in libmsvcrt-os.a for arm/arm64, and
improves the acosh function for x86.
 2019-04-16 14:53:54 +03:00

Martin Storsjö 84bdd9c4e8 Set the correct CMake option CMAKE_CROSSCOMPILING in build-llvm.sh 
The previous option doesn't seem to have had any effect, and cmake
correctly has warned about an unused option.

Also set the value of the option to TRUE, for slightly more consistency
with where this option is set in build-llvm.sh.
 2019-04-16 10:27:25 +03:00

When using the floor function from msvcrt/ucrt instead of a libmingwex
reimplementation, this test passes on arm as well.
 2019-04-15 14:05:46 +03:00
Martin Storsjö 5f846336c0 Bump to a newer version of mingw-w64 
This version contains a number of improvements for the arm CRT
libraries.

Martin Storsjö 7c2067f19f Build and keep llvm-cov and llvm-profdata 
These might be useful now that the profiling library in compiler-rt
works.
 2019-03-29 23:09:41 +02:00
Martin Storsjö 13d73ee670 Update compiler-rt to a new version 
This version fixes undefined symbols in the profiling library.
 2019-03-29 23:07:57 +02:00
Martin Storsjö 666a26307d Revert "Mention the fact that binutils can't use the generated import libraries" 
This reverts commit 9367988be7.

binutils actually can handle the short import format just fine.
It only has got issues with base mingw import libraries that contain
symbol aliases (which in llvm-dlltool is implemented via weak
symbols, and linking to weak symbols differ a bit between lld and
binutils ld).
 2019-03-24 22:16:08 +02:00
Martin Storsjö 4e58a5a9a0 Update llvm/clang/lld to a recent version 
Since the previous pinned version, there was one fix relevant for
windows on aarch64.
 2019-03-19 09:44:01 +02:00
Martin Storsjö b3ff7b278d Update libcxx to the 8.0 release version 
libunwind and libcxxabi are kept at the previously pinned versions, past
the 8.0 branch.
 2019-03-19 09:40:46 +02:00
Martin Storsjö f39d45162e Update compiler-rt to the 8.0 release version 
This doesn't fix any particular known issue, but the release branch
should generally be a safe version.
 2019-03-19 09:34:19 +02:00
Martin Storsjö b9e0685167 Update mingw-w64 to the latest version from today 2019-03-19 00:30:54 +02:00
Martin Storsjö 4a7cb27899 Don't error out if git-svn is unavailable 
This should avoid leaving the llvm tree checked out at a version other
than the pinned one, if git-svn failed or wasn't available.
 2019-03-16 10:53:00 +02:00
Martin Storsjö 005b8efd91 Allow building a full llvm install 2019-03-15 23:56:18 +02:00
Martin Storsjö 25c3bd8593 Set LLVM_COMPILER_CHECKED when bootstrapping libunwind/libcxxabi/libcxx 
The checks behind LLVM_COMPILER_CHECKED fail if there's no libc++
available for linking.

This fixes building libunwind/libcxxabi/libcxx with newer versions
of llvm, if the llvm installation isn't stripped.
 2019-03-15 23:53:20 +02:00
Martin Storsjö 4b537369ca Add more proper references to dwarf issues on i686 2019-03-01 10:28:00 +02:00

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
