Martin Storsjö 7194894b4a Build C++ things for arm64 as well 
This requires updating to the latest version of mingw-w64.
 2017-08-28 23:02:36 +03:00
Martin Storsjö 3fc98d9d8a Remove a leftover --depth=1 
That obviously doesn't work when wanting to check out a specific,
possibly older, revision.

 2017-08-25 14:01:16 +03:00
Martin Storsjö 3e1dfb2e79 Initialize the llvm/clang checkouts with git-svn 
This produces more sensible version numbers in the clang --version
output.
 2017-08-23 12:54:08 +03:00

Martin Storsjö 935d8f40ad Add a comment about a patch that now has been upstreamed 2016-11-19 23:45:12 +02:00
Martin Storsjö 1957272cd5 Remove the compiler-rt mingw/arm patch 
This has now been committed upstream in the master branch (we
check out the master branch of compiler-rt, not the 3.9 branch),
in SVN rev 287465 (git mirror commit 8134888c4d01).
 2016-11-19 23:34:12 +02:00
Martin Storsjö 701bc94b8f Update the compiler-rt patches for building for arm/mingw 
The second one, for msvc mode (which vlc doesn't need anyway), isn't
necessary now that llvm has been patched to emit calls properly using
the msvc helper function names.
 2016-11-01 11:16:30 +02:00
Martin Storsjö be1357f467 Backport more llvm patches from current master 
This fixes up handling of divisions on ARM/Windows, and consistently
does calls to helper functions using the windows/msvc names, instead
of the libgcc naming.
 2016-11-01 11:13:50 +02:00
Martin Storsjö f3b034f10a Clang/LLVM 3.9 is now 3.9.1 2016-10-04 10:41:54 +03:00

Martin Storsjö c1e32c9587 Updated libunwind, libcxx and libcxx patches and build commands 
Build libcxx and libcxxabi (succeeding) and libunwind (patch rebased
but build not working).
 2016-08-31 12:25:08 +03:00
Martin Storsjö 0e847128ef Add mingw patches for fixing math functions 2016-08-27 22:48:15 +03:00
Martin Storsjö d71fab8802 Add a patch for adding open/read/write/close/setmode aliases to the arm msvcrt 
This requires using llvm-dlltool, since genlib currently doesn't
support aliases.
 2016-08-27 22:48:15 +03:00
Martin Storsjö e22accd247 Build compiler-rt using cmake, add arm division and float/int64 conversion routines 
Build using the master branch instead of 3.9.

By building using cmake, we don't need to build the files that
require an upper case Windows.h.
 2016-08-27 22:48:15 +03:00
Martin Storsjö 8afb6e784f Clone and patch mingw after building llvm 
This avoids having to rebuild llvm when adjusting mingw patches.
 2016-08-27 22:48:15 +03:00
Martin Storsjö 9dd4e7318c Use llvm-dlltool instead of genlib 2016-08-27 22:48:15 +03:00

Martin Storsjö 4de5f192a6 Add a clang patch for adding support for __declspec(selectany) 2016-08-24 23:36:44 +03:00
Martin Storsjö 77e76bea00 Force using llvm-ranlib and llvm-ar when building the builtins 
This avoids having to manually call ranlib later.
 2016-08-24 23:26:32 +03:00
Martin Storsjö 8b36ede40d Update the mingw patch for ctors 2016-08-24 23:25:01 +03:00
Martin Storsjö 7638232b38 Only copy the patches right before they will be applied 
This avoids having to rebuild things, whose patches haven't
changed.
 2016-08-11 21:06:47 +03:00
Martin Storsjö 00b9d91251 Build the full llvm/clang 
The target CppBackend doesn't seem to exist in 3.9
 2016-08-11 21:06:47 +03:00
Martin Storsjö 0010386360 Fix an issue with lld and llvm-ar 3.9 vs genlib 2016-08-11 21:06:47 +03:00
Martin Storsjö 362538a9a4 Explain more why the Windows.h symlink is needed 2016-08-10 14:52:16 +03:00
Martin Storsjö 4449d80c05 Patch compiler-rt to fix "make clang_mingw" with the 3.9 branch 2016-08-10 14:52:16 +03:00
Martin Storsjö 9e44ca1b07 Switch from the 3.8 branch to 3.9 
The 3.8 branch produces broken code for divisions on arm/windows.
The brokenness can appear as incorrect behaviour or crashes.

The 3.9 branch isn't released yet, but is probably a better target
to base any work on at the moment.
 2016-08-10 14:52:16 +03:00
Martin Storsjö 93a77a441a Update patches for lld 3.9 
The previously existing patch needed some modifications to fit
on top of lld 3.9.

Patch 2 makes sure that one still can use the lld built in this
way for linking in MSVC mode.

Patch 3 fixes linking binaries larger than 4 MB or so (previously
the binaries linked fine but didn't work).

Patch 4 makes sure to error out if the relocations are too far
away (instead of producing a broken binary), which happens after
16 MB.

Patch 5 fixes relocations that have an offset, which probably
happens in hand-written assembly (in libav).
 2016-08-10 14:52:16 +03:00
Martin Storsjö 3eb63bea3d Apply patches for LLVM 3.9 
Patches 1 and 2 fix a bug (that has been present in 3.7 and 3.8)
where it can use the wrong instruction in some cases (libav
with inline assembly disabled), causing rounding errors in
integer audio dct's there.

Patch 3 allows building inline assembly with clang/llvm in MSVC mode.
 2016-08-10 14:52:16 +03:00
Martin Storsjö feac2f56ba Update patches for clang 3.9 
Patches 1-2 are just rebased from the earlier version for clang
3.8, no changes in surrounding code there.

Patch 3 is necessary to fix a regression in assembling standalone
assembly files in 3.9.

Patch 4 makes clang work in MSVC mode with the MSVC SDK for ARM
(to simplify testing of the toolchain in that mode).

Martin Storsjö 9dc7babfc1 Comment out building libunwind 
This failed building for me, so skip it for now.
