This contains new declarations that the latest version of llvm
requires, when building llvm for windows on aarch64.
Notable changes are:
- Fixed compatibility fallbacks for running libc++ on Windows 7
- Improved handling of multibyte functions with UCRT
- Fixed installing mingw-w64-crt and widl in paths that contain spaces
- Fixed sscanf with double output on arm/aarch64
- Improved math functions, in particular for arm/aarch64
This makes it easier to change the default win32 target when using
build-all.sh, and also makes it possible to change the version of
mingw-w64 that is used, which wasn't possible at all before.
build-mingw-w64.sh already provides --with-default-msvcrt option, but
this makes it more convenient to use build-all.sh with non-default
msvcrt config.
On windows, we rename clang.exe to clang-$MAJOR.exe, and later
install clang.exe as a wrapper for the default architecture. But
if only building certain architectures, and the host architecture
isn't one of them, we shouldn't install any unprefixed clang.exe at
all.
For build-mingw-w64.sh to succeed when installing to such a path,
the mingw-w64 version has to be updated to the latest git master.
build-mingw-w64-libraries.sh still fails in this case, as libtool
fails to properly quote $LD in a test for whether the linker is GNU ld.
Since the default _WIN32_WINNT now is for Windows 7, psapi.h
redirects to PSAPI version 2, which is available in kernel32.dll
with a "K32" prefix on the function names (K32EnumProcessModules).
On some distributions, e.g. openSUSE, the libraries for 64 bit
architectures end up stored in <target>/<triplet>/lib64 instead of
plain "lib".
(This is caused by their use of a site script for configure, which
overrides libdir when the host triplet matches 64 bit architecture
names - even if it's a triple for cross compilation for a totally
different OS. This only affects the libraries and not mingw-w64-crt,
as the crt's makefiles manually set the output directory name.)
This fixes https://github.com/mstorsjo/llvm-mingw/issues/51.
This version contains fixes for wchar printf functions in how they
handle %s/%S formats.
This isn't the absolute latest version, as there's other commits further
ahead adding support for _FORTIFY_SOURCE (which has little to no effect
with Clang as it doesn't evaluate __builtin_object_size in inlined
contexts), and the commits for _FORTIFY_SOURCE caused a few regressions,
and things might still be a bit in flux (even though the current master
seems to work fine).
This makes cmake use relative paths to all source files, allowing ccache
to reuse compilation results from different source trees in different
directories.
Keep using LLVM_ENABLE_PROJECTS on msys, where symlinks aren't supported.
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.
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.
