Martin Storsjö 353af4ba24 readme: Add a note about incompatibility with object files and static libraries from other toolchains 2020-03-14 13:51:30 +02:00
Martin Storsjö 5938c12227 readme: Recommend installing python3 instead of python2 
Nowadays msys2 provides python 3.8 in the python3 package, so the
previous bug regarding running subprocesses in python3 is fixed.

Martin Storsjö 3d13aefc70 Bump the default _WIN32_WINNT to 0x0601, i.e. Windows 7 
Since the C++ libraries require Windows 7, there's little point in
keeping the default target for C at Vista.

Martin Storsjö dcf34a9a35 readme: The minimum Windows version that libc++ runs on is Windows 7 
It uses TryAcquireSRWLockExclusive which didn't exist until Windows 7,
unlike the rest of the SRWLock APIs that appeared in Vista.

Martin Storsjö 89e0891d8f readme: Remove the note about only being tested on macos and linux 
It has recently been tested on msys2 as well, with few changes since
the last time it was tested.

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).

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 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.

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.

Martin Storsjö a38e52fff5 Build address sanitizer 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).

Martin Storsjö d25e4d5be7 Remove a known issue with debugging x86_64 binaries 
With SEH in use now, this is no longer an issue.
 2018-08-08 08:43:05 +03:00
Martin Storsjö af4e0b0021 readme: Remove the issue about libunwind vs WinRT 
libwinstorecompat now provides a reimplementation of EnumProcessModules,
making libunwind compatible with WinRT.
 2018-07-16 23:30:54 +03:00
Martin Storsjö b73785af3b Fix a typo in the readme about PDB output 2018-06-02 23:03:42 +03:00

Martin Storsjö ecdb6647b7 windres: Remove the rc filtering in the wrapper shell script 
llvm-rc does this filtering internally now.
 2018-05-11 09:48:07 +03:00
Martin Storsjö decfd0030b Update README.md about using llvm-rc instead of GNU binutils windres 2018-05-07 09:44:41 +03:00

Martin Storsjö 53be941850 Mention a few more known issues 2018-01-23 11:22:48 +02:00
Martin Storsjö 583baaa612 Make windres output in res format instead of in coff 
This makes the output architecture independent, allowing
the x86_64 GNU binutils binary to be used for other
architectures as well, including arm/arm64 which aren't supported
by binutils.
 2018-01-10 10:53:02 +02:00
Martin Storsjö 55e8aef024 Provide <triplet>-<tool> wrappers and links to many llvm tools 
Provide wrappers named <triplet>-gcc and <triplet>-g++ as well,
to ease cross compilation with e.g. autotools, to allow just
specifying --host=<triplet>.

Provide wrappers for objdump and ld that provide specific output
that autotools look for.

Provide <triplet>-strip as a symlink to /bin/true, since there is
no strip tool available yet (and llvm-objcopy doesn't support
COFF yet).
 2018-01-10 10:53:02 +02:00
Martin Storsjö e56a519fdc Split the building of the toolchain into individual shellscripts 
This simplifies building the toolchain outside of docker.
 2018-01-10 10:24:48 +02:00
Martin Storsjö 4fc70f4a23 Add --sysroot to the compiler invocation 
This makes sure the right sysroot is used, even if e.g. a global
system installation of x86_64-w64-mingw32-gcc exists under /usr.

Martin Storsjö 89afcc42f6 Clarify other branches with content of value 2017-12-20 11:43:08 +02:00
Martin Storsjö 634ae81950 Pass -femulated-tls to the compiler by default 
The MinGW CRT wrapping has a few minor issues that makes native
TLS fail at the moment.

LLVM doesn't support native TLS on windows/aarch64, but emulated
TLS is supported now.
 2017-12-04 13:49:32 +02:00
Martin Storsjö 03f1fd6c65 Use dwarf exceptions on armv7 and aarch64 
Dwarf is also the default in clang on i686, but libunwind currently
has an issue relating to unwinding dwarf exceptions on i686 on
windows (and less easily reproducible on other platforms),
see https://reviews.llvm.org/D38680.

This enables exceptions on aarch64, where they previously were
avoided/disabled.

When linking to a statically linked libunwind with support for
dwarf, one (currently) has to link in -lpsapi.
