This test passes on Windows when using Python 3 but fails when using Python 2, so it needs more investigation before it can be enabled as the bots use Python 2.

clang doesn't use line number 0 (to mean artifically generated code) very often, but swift does it
quite often. We were rejecting all by line breakpoints in functions that started at line 0. But that's
a special marker so we can just not do this test in that case.

Double quotes are always correct in paths on windows while single quotes only work sometimes. By swapping the order of the quotes in the subsitution we guarantee that the quotes will be correct on Windows. Both sets work correctly on Linux in the test environment.
llvm-svn: 339180
Summary:
In Python2 'unicode' is a distinct type from 'str', but in Python3 'unicode' does not exist and instead all 'str' objects are Unicode string. This change updates the logic in the test logging for lit to correctly process each of the types, and more importantly, to not just fail in Python3.
This change also reverses the use of quotes in several of the cfg files. By using '""' we are guaranteeing that the resulting path will work correctly on Windows while "''" only works correctly sometimes. This also fixes one of the failing tests.

This patch extends CFGSort pass to support exception handling. Once it
places a loop header, it does not place blocks that are not dominated by
the loop header until all the loop blocks are sorted. This patch extends
the same algorithm to exception 'catch' part, using the information
calculated by WebAssemblyExceptionInfo class.

We do need to map /Zi to /Z7 explicitly for msbuild as explained in this file,
but since /Zi is passed by default and since things transparently work fine
with it mapped to /Z7, we shouldn't produce effectively inactionable noise for
it.
Also don't warn on /X since clang-cl supports that (since r326357; the risk of
duplicating a bunch of clang-cl driver logic here).

Compiling the following causes clang to crash
```
char *cmp(__attribute__((address_space(1))) char *x, __attribute__((address_space(2))) char *y) {
return x < y ? x : y;
}
```
with the message: "wrong cast for pointers in different address
spaces(must be an address space cast)!"
This is because during IR emission, the source and dest type for a
bitcast should not have differing address spaces.
This fix prints an error since the code shouldn't compile in the first place.

If /subsystem:windows is passed, link.exe only looks for WinMain and wWinMain,
and if /subsystem:console is passed it only looks for main and wmain. lld-link
used to look for all 4 in both cases. This patch makes lld-link match
link.exe's behavior.
This requires that the subsystem is known by the time findDefaultEntry() gets
called. findDefaultEntry() is called before the main link loop, so that the
loop can mark the entry point as undefined. That means inferSubsystem() has to
be called above the main loop as well. This in turn means /subsystem: from
.drectve sections only has an effect on entry point inference for obj files
passed to lld-link directly (and not in obj files found later in .lib files).
link.exe seems to ignore /subsystem: for obj files from lib files completely
(while in lld it's ignored only for entry point detection but it still
overrides /subsystem: flags passed on the command line for the value that gets
written in the output file).
Also, if the subsytem isn't needed (e.g. when only writing a /def: lib file and
not writing a coff file), link.exe doesn't complain if the subsystem isn't
known, so both subsystem and entry point handling should be below the early
return lld has for that case.
Fixes PR36523.

There were previously no instructions for building LLDB on Mac OS X
with CMake. It's sufficiently close to building on Linux/FreeBSD/NetBSD that a
well-motivated developer could figure out the steps themselves. However, having
an explicit guide is better and can provide Mac OS X specific configurations
(e.g. LLDB_BUILD_FRAMEWORK).

llvm-svn: 339152
Summary:
Hello!
This commit adds a LLVM-C target that is always built on MSVC. A big fat warning, this is my first cmake code ever so there is a fair bit of I-have-no-idea-what-I'm-doing going on here. Which is also why I placed it outside of llvm-shlib as I was afraid of breaking things of other people. Secondly llvm-shlib builds a LLVM.so which exports all symbols and then does a thin library that points to it, but on Windows we do not build a LLVM.dll so that would have complicated the code more.
The patch includes a python script that calls dumpbin.exe to get all of the symbols from the built libraries. It then grabs all the symbols starting with LLVM and generates the export file from those. The export file is then used to create the library just like the LLVM-C that is built on darwin.
Improvements that I need help with, to follow up this review.
- Get cmake to make sure that dumpbin.exe is on the path and wire the full path to the script.
- Use LLVM-C.dll when building llvm-c-test so we can verify that the symbols are exported.
- Bundle the LLVM-C.dll with the windows installer.
Why do this? I'm building a language frontend which is self-hosting, and on windows because of various tooling issues we have a problem of consuming the LLVM*.lib directly on windows. Me and the users of my projects using LLVM would be greatly helped by having LLVM-C.dll built and shipped by the Windows installer. Not only does LLVM takes forever to build, you have to run a extra python script in order to get the final DLL.
Any comments, thoughts or help is greatly appreciated.
Cheers, Jakob.
