Removing the native CMakeCache.txt causes the target to get re-run needlessly
on some systems. We'll want another solution for that part of the fix.

Were inserted in the CopyFiles phase of the "desktop" aggregate target.  That caused them to get
copied to /usr/shared/man/man1 on install, which isn't right.  Not sure why they were there...
I removed them.  If this was supposed to achieve some other purpose, we should discuss how to do
that correctly on the mailing list.

Just tried this on a few tests and this was the only one that was
easily ported to use the new feature, so we'll go with that for now.
Hopefully can act as inspiration/reminder for other tests.

Not all debug info tests need to check for every DW_TAG or NULL child
terminator, but perhaps they should (just to ensure they don't accidentally
end up with tags nested inside other tags without the test failing, for example)

This adds support for building native artifacts when cross-compiling using the
popular side-by-side source directory layout (no symlinks, no nested
repositories).

Add a `MapVector::remove_if()` that erases items in bulk in linear time,
as opposed to quadratic time for repeated calls to `MapVector::erase()`.

Assuming single precision denormals and accurate sqrt/div are not
reported, this passes the OpenCL conformance test.

The registration scheme used in r211652 violated the read-only contract of
MemoryBuffer. This caused crashes in llvm-rtdyld where macho objects were backed
by read-only mmap'd memory.

Imagine, hypothetically, that you had a build of clang-tidy that enabled
the google-* checks by default.  If you had such a binary, then this
test would fail.  Making it pass in that configuration isn't such a bad
thing.

llvm-svn: 213085

Actually update the changed indexes in the map portion of `MapVector`
when erasing from the middle.  Add a unit test that checks for this.

Note that `MapVector::erase()` is a linear time operation (it was and
still is).  I'll commit a new method in a moment called
`MapVector::remove_if()` that deletes multiple entries in linear time,
which should be slightly less painful.

Summary:
This implements the -arch flag for both x86 and x86-64 by letting
them affect the default target features we pass to cc1.  -m machine
flags will override the features set by -arch.

The coalescer is very aggressive at propagating constraints on the register classes, and the register allocator doesn’t know how to split sub-registers later to recover. This patch provides an escape valve for targets that encounter this problem to limit coalescing.

This patch also implements such for ARM to lower register pressure when using lots of large register classes. This works around PR18825.

llvm-svn: 213078

There are two forms of `-l` prefixed expression:

* -l<libname>
* -l:<filename>

In the first case a linker should construct a full library name
`lib + libname + .[so|a]` and search this library as usual. In the second case
a linker should use the `<filename>` as is and search this file through library
search directories.

The patch reviewed by Shankar Easwaran.

Summary:
We still allow the escape hatch foo(int /*x*/) and also suggest this
in a fixit. This is more powerful than the corresponding cpplint.py check
it also flags functions with multiple arguments as naming all arguments is
recommended by the google style guide.

This patch adds two new rules to the DAGCombiner:
 1.  shuffle (shuffle A, Undef, M0), B, M1 -> shuffle A, B, M2
 2.  shuffle (shuffle A, Undef, M0), A, M1 -> shuffle A, Undef, M2

We only do this if the combined shuffle is legal for the target.

Example:
;;
define <4 x float> @test(<4 x float> %a, <4 x float> %b) {
  %1 = shufflevector <4 x float> %a, <4 x float> undef, <4 x i32><i32 6, i32 0, i32 1, i32 7>
  %2 = shufflevector <4 x float> %1, <4 x float> %b, <4 x i32><i32 1, i32 2, i32 4, i32 5>
  ret <4 x i32> %2
}
;;
