fe112c27a2 llvm-build: Adopt generation of LLVM_LIBS_TO_EXPORT. Patch by
Brad King.

Move `LLVM_LIBS_TO_EXPORT` over to Makefile.llvmbuild and generate it
from `llvm-build` using the same logic used to export the dependencies
of these libraries.  This avoids depending on `llvm-config`.

This refactoring was originally motivated by issue #24154 due to commit
r243297 (Fix `llvm-config` to emit the linker flag for the combined
shared object, 2015-07-27) changing the output of `llvm-config --libs`
to not have the individual libraries when we configure with
`--enable-shared`.  That change was reverted by r244108 but this
refactoring makes sense on its own anyway.

71481ee8c0 llvm-build: Factor out duplicate cmake export listing. Patch by
Brad King.

The write_cmake_fragment and write_cmake_exports_fragment methods share
some logic for selecting libraries that CMake needs to know about.
Factor it out into a helper to avoid duplication.

After r244870 flush() will only compare two null pointers and return,
doing nothing but wasting run time. The call is not required any more
as the stream and its SmallString are always in sync.

52ab0bc417 [PM/AA] Extract the ModRef enums from the AliasAnalysis class in
preparation for de-coupling the AA implementations.

In order to do this, they had to become fake-scoped using the
traditional LLVM pattern of a leading initialism. These can't be actual
scoped enumerations because they're bitfields and thus inherently we use
them as integers.

I've also renamed the behavior enums that are specific to reasoning
about the mod/ref behavior of functions when called. This makes it more
clear that they have a very narrow domain of applicability.

I think there is a significantly cleaner API for all of this, but
I don't want to try to do really substantive changes for now, I just
want to refactor the things away from analysis groups so I'm preserving
the exact original design and just cleaning up the names, style, and
lifting out of the class.

9994b911f4 Targets: commonize some stack realignment code
This patch does the following:
* Fix FIXME on `needsStackRealignment`: it is now shared between multiple targets, implemented in `TargetRegisterInfo`, and isn't `virtual` anymore. This will break out-of-tree targets, silently if they used `virtual` and with a build error if they used `override`.
* Factor out `canRealignStack` as a `virtual` function on `TargetRegisterInfo`, by default only looks for the `no-realign-stack` function attribute.

Multiple targets duplicated the same `needsStackRealignment` code:
 - Aarch64.
 - ARM.
 - Mips almost: had extra `DEBUG` diagnostic, which the default implementation now has.
 - PowerPC.
 - WebAssembly.
 - x86 almost: has an extra `-force-align-stack` option, which the default implementation now has.

The default implementation of `needsStackRealignment` used to just return `false`. My current patch changes the behavior by simply using the above shared behavior. This affects:
 - AMDGPU
 - BPF
 - CppBackend
 - MSP430
 - NVPTX
 - Sparc
 - SystemZ
 - XCore
 - Out-of-tree targets
This is a breaking change! `make check` passes.

The only implementation of the `virtual` function (besides the slight different in x86) was Hexagon (which did `MF.getFrameInfo()->getMaxAlignment() > 8`), and potentially some out-of-tree targets. Hexagon now uses the default implementation.

`needsStackRealignment` was being overwritten in `<Target>GenRegisterInfo.inc`, to return `false` as the default also did. That was odd and is now gone.

8fd1953423 [lit] Implement 'env' in the internal shell

Other than that, this saves a subprocess invocation of a small unix
utility, which is makes the tests faster.

The internal shell does not support shell variable expansion, so this
idiom in the ASan tests isn't supported yet:

Summary:
Adds '--svn-path BRANCH' that causes the script to export the specified path
from each project. Otherwise the tag specified by -release, -rc, etc. will be
used. The version portion of the package name will be 'test-$path' (any forward
slashes in the branch name are replaced with underscores), for example:
  -svn-path trunk => clang+llvm-test-trunk-mips-linux-gnu.tar.xz
  -svn-path branches/release_35 => clang+llvm-test-branches_release_35-mips-linux-gnu.tar.xz

This is primarily useful for bringing new release packages up to standard
without needing to create and maintain a tag for the purpose.

This change is part of a series of commits dedicated to have a single

This patch is quite boring overall, except for some uglyness in
ASMPrinter which has a getDataLayout function but has some clients
that use it without a Module (llmv-dsymutil, llvm-dwarfdump), so
some methods are taking a DataLayout as parameter.

f9893938de Switch the release script to build with CMake by default (PR21561)
It retains the possibility to use the autoconf build with a
command-line option ('-use-autoconf'), and uses that by default on Darwin since
compiler-rt requires it on that platform.

This commit also removes the "Release-64" flavour and related logic. The script
would previously do two builds unless the '-no-64bit' flag was passed, but on
my machine and from those I asked this always ended up producing two 64-bit builds,
causing much confusion.

It also removes the -build-triple option, which caused the --build= flag to
get passed to ./configure. This was presumably intended for cross-compiling,
but none of the release testers use it. If someone does want to pass it,
they can use '-configure-flags --build=foo' instead.

d2e1e42c1a [TableGen] Improve decoding options for non-orthogonal instructions
When FixedLenDecoder matches an input bitpattern of form [01]+ with an
instruction bitpattern of form [01?]+ (where 0/1 are static bits and ? are
mixed/variable bits) it passes the input bitpattern to a specific instruction
decoder method which then makes a final decision whether the bitpattern is a
valid instruction or not. This means the decoder must handle all possible
values of the variable bits which sometimes leads to opcode rewrites in the
decoder method when the instructions are not fully orthogonal.

The patch provides a way for the decoder method to say that when it returns
Fail it does not necessarily mean the bitpattern is invalid, but rather that
the bitpattern is definitely not an instruction that is recognized by the
decoder method. The decoder can then try to match the input bitpattern with
other possible instruction bitpatterns.

For example, this allows to solve a situation on AArch64 where the `MSR
(immediate)` instruction has form:
1101 0101 0000 0??? 0100 ???? ???1 1111
but not all values of the ? bits are allowed. The rejected values should be
handled by the `extended MSR (register)` instruction:
1101 0101 000? ???? ???? ???? ???? ????

The decoder will first try to decode an input bitpattern that matches both
bitpatterns as `MSR (immediate)` but currently this puts the decoder method of
`MSR (immediate)` into a situation when it must be able to decode all possible
values of the ? bits, i.e. it would need to rewrite the instruction to `MSR
(register)` when it is not `MSR (immediate)`.

The patch allows to specify that the decoder method cannot determine if the
instruction is valid for all variable values. The decoder method can simply
return Fail when it knows it is definitely not `MSR (immediate)`. The decoder
will then backtrack the decoding and find that it can match the input
bitpattern with the more generic `MSR (register)` bitpattern too.

fb17afba61 Fix several issues with the test-release.sh script
* Use the default install prefix (/usr/local) and use DESTDIR instead to
  set a temporary install location for tarballing. This is the correct
  way to package binary releases (otherwise the temporary install path
  ends up in files in the binary release).
* Remove ``-disable-clang`` option. It did not work correctly
  (tarballing assumed phase 3 was run) and when doing a release
  we should always be doing a three-phased build and test.

Note: Technically we should only be using DESTDIR for the third phase
and use --prefix for the first and second phase because we run the built
clang from phase 1 and 2 (and in general an application's behaviour
may depend on the install prefix). However in the case of clang it
seems to not care what the install prefix was so to simplify the script
we use DESTDIR for all three stages.

a0a51734cd AVX-512: Added all AVX-512 forms of Vector Convert for Float/Double/Int/Long types.
In this patch I have only encoding. Intrinsics and DAG lowering will be in the next patch.
I temporary removed the old intrinsics test (just to split this patch).
Half types are not covered here.

16859aa242 MC: Remove MCSubtargetInfo() default constructor
Force all creators of `MCSubtargetInfo` to immediately initialize it,
merging the default constructor and the initializer into an initializing
constructor.  Besides cleaning up the code a little, this makes it clear
that the initializer is never called again later.

Out-of-tree backends need a trivial change: instead of calling:

    auto *X = new MCSubtargetInfo();
    InitXYZMCSubtargetInfo(X, ...);
    return X;

they should call:

    return createXYZMCSubtargetInfoImpl(...);

There's no real functionality change here.

99cb989593 Target RegisterInfo: devirtualize TargetFrameLowering
Summary:
The target frame lowering's concrete type is always known in RegisterInfo, yet it's only sometimes devirtualized through a static_cast. This change adds an auto-generated static function <Target>GenRegisterInfo::getFrameLowering(const MachineFunction &MF) which does this devirtualization, and uses this function in all targets which can.

This change was suggested by sunfish in D11070 for WebAssembly, I figure that I may as well improve the other targets while I'm here.

8f32e5f0d6 Rename llvm.frameescape and llvm.framerecover to localescape and localrecover
Summary:
Initially, these intrinsics seemed like part of a family of "frame"
related intrinsics, but now I think that's more confusing than helpful.
Initially, the LangRef specified that this would create a new kind of
allocation that would be allocated at a fixed offset from the frame
pointer (EBP/RBP). We ended up dropping that design, and leaving the
stack frame layout alone.

These intrinsics are really about sharing local stack allocations, not
frame pointers. I intend to go further and add an `llvm.localaddress()`
intrinsic that returns whatever register (EBP, ESI, ESP, RBX) is being
used to address locals, which should not be confused with the frame
pointer.

Naming suggestions at this point are welcome, I'm happy to re-run sed.

9fb4897162 Fix bug in test-release.sh where the script would not exit if any
of the build stages that are sent through a pipe (e.g. tee) failed.

This potentially allowed builds and/or tests to fail without anyone
noticing. It appears that for the LLVM 3.6.[01] releases this actually
happened for the Ubuntu 14.04LTS binary releases. The essence of the
issue is that without ``set -o pipefail`` the following command in bash
has a zero exit code.

false | tee /dev/null ; exit $?
