This should make the produced artifact more widely compatible.
Releases built with release.sh with the dockerfile are currently
based on Ubuntu 18.04 though, and are more shielded from potential
extra libraries that are found during the build.
For non scheduled builds, those env variables are just left empty.
This is much neater than using the "versions" file, and uses much
fewer lines of code.
We still probably want to bundle a file labelling what versions
it contains in the built packages though; give that file a
.txt suffix.
Since e56fb975e9, strip-llvm.sh
has been called as part of build-all.sh.
This avoid stripping out files that have been installed into the
share directory by later stages in build-all.sh. (strip-llvm.sh
currently flat out removes the share directory.)
Keep removing the same items installed by LLVM as before (although
that could be revisited too).
This avoids removing unintended files if running strip-llvm after
the installation of other components.
These test suites now pass in the latest git main.
This target isn't run automatically anywhere, but in case the
target is enabled to run the tests, include the libcxxabi and libunwind
test suites too.
These no longer fail; they were fixed in ffmpeg in commit
76b33704b628248d77ed61cbef9ecd9430a4b6c5 in July 2022; we currently
test a pinned 6.0 release, where this fix is included.
This reduces the differences if using a proper release tarball
instead of an artifact from an earlier step (if testing parts of
the workflow by modifying it).
This was added in 050b4ef701, but this
option was never supported to be passed on to build-llvm.sh from
here.
Additionally, this option was removed entirely from build-llvm.sh
in bd190c04c3.
Normally our releases are cross-built from Linux, but we also
support building the toolchain in MSYS2. Enable the custom defaults
when building the toolchain in MSYS2 too.
Configuring the mingw-w64-crt build takes a really long time on MSYS2;
the generating Makefile phase takes easily 4-5 minutes, when the rest
of configure runs in a matter of seconds. By passing
--disable-dependency-tracking, the whole configure for mingw-w64-crt
takes 11-14 seconds where it previously took many mnutes.
This comes with the drawback that these build directories aren't
suitable for incremental development (unless manual care is taken
to rebuild all necessary files), but these builds are mostly done
for non-interactive building.
Thanks to Jeremy Drake for realizing this optimization opportunity,
and LIU Hao for making me aware of it.
Notable changes for mingw users are:
- Support demangling C++ symbols on i386 in LLVM backtraces
- Don't report fatal errors when the output pipe is closed on Windows
- Ignore file access times on Windows when comparing whether files are
equivalent
Notable changes:
- Support for _FORTIFY_SOURCE=3
- Fortification of [v]s[n]printf for UCRT
- Add the __gets_chk function, for fortification of the (highly
deprecated) gets function
- Fixed the inconsistent signature of the wcstok function on UCRT
in string.h
- Allow opting out from SEH based setjmp/longjmp by defining
__USE_MINGW_SETJMP_NON_SEH before including setjmp.h
And as usual, lots of other minor updates.
This allows the wrappers to invoke the right tool with the right
options, even when the wrapper was invoked with an obfuscated
short form file name.
This happens e.g. when CMake/Ninja invokes the tools from a path
that contains spaces.
While $HOST-clang is more specific for the use in llvm-mingw,
using the form $HOST-gcc would allow using the same script in
GCC based environments too.
Keep this disabled by default (since it takes a fair amount of time
and has good test coverage upstream), but including it in disabled
form so that it's easy to enable temporarily for testing occasionally.
Libcxx does test the mingw configuration in their own CI (with an older
pinned release of the compiler), so this is mostly redundant, and
primarily relevant for testing that the very latest compiler (and
python setup) works for the tests.
It is available on all architectures by default now. Keep the
HAVE_OPENMP conditional within the test makefile to allow custom
testing without having it available.
Since a356782426f5bf54a00570e1f925345e5fda7b2e in llvm-project,
OpenMP can be built for mingw/aarch64, since
fb947c358661b3bd3d5e1fa776ec74cc0f308854 it should work correctly
in all currently tested cases, and since
97958c9bb83cec44b6ce13e732b53de0171a5d43 it can be built for
mingw/armv7.
Curl (or wget) isn't required for fetching libssp any longer,
so don't require it while running build-all.sh.
(It's still required by build-cross-tools.sh, for build-make.sh
though.)
Since using the ssp routines from mingw-w64 instead of those from
GCC's libssp, these messages are included in the piped output of
the process, so we can check for the right messages.
As mingw-w64 now provides these routines, we no longer need to build
the original library from GCC.
As building with -fstack-protector-strong still links with -lssp
(and -lssp_nonshared), we still need to provide libraries with these
names, but they can be empty dummy libraries.
Notable changes:
- Support for CFGuard
- SSP routines are bundled as part of libmingwex, rendering the separate
libssp from GCC unnecessary
Plus lots and lots of various other minor fixes and improvements.
