This patch fixes bug https://llvm.org/bugs/show_bug.cgi?id=27897.
When query memory access cost, current SLP always passes in alignment value of 1 (unaligned), so it gets a very high cost of scalar memory access, and wrongly vectorize memory loads in the test case.
It can be fixed by simply giving correct alignment.

when the object is from a slice of a Mach-O Universal Binary use something like
"foo.o (for architecture i386)" as part of the error message when expected.
Also fixed places in these tools that were ignoring object file errors from
MachOUniversalBinary::getAsObjectFile() when the code moved on to see if
the slice was an archive.
To do this MachOUniversalBinary::getAsObjectFile() and
MachOUniversalBinary::getObjectForArch() were changed from returning
ErrorOr<...> to Expected<...> then that was threaded up to its users.
Converting these interfaces to Expected<> from ErrorOr<> does involve
touching a number of places. To contain the changes for now the use of
errorToErrorCode() is still used in two places yet to be fully converted.

Code like the following is considered broken, and doesn't need to be
supported by our AA magicks:
void getFoo(int *P) {
int *PAlias = (int *)((char *)NULL + (uintptr_t)P);
}
This patch makes CFLAA drop support for code like this.

We think it's OK to generate half fminnan because it's legal for the
transform-to type (f32; r245196). However, PromoteFloatRes was missing
the case; simply promote like the other binops, including minnum.

Adds the method MCStreamer::EmitBinaryData, which is usually an alias
for EmitBytes. In the MCAsmStreamer case, it is overridden to emit hex
dump output like this:
.byte 0x0e, 0x00, 0x08, 0x10
.byte 0x03, 0x00, 0x00, 0x00
.byte 0x00, 0x00, 0x00, 0x00
.byte 0x00, 0x10, 0x00, 0x00
Also, when verbose asm comments are enabled, this patch prints the dump
output for each comment before its record, like this:
# ArgList (0x1000) {
# TypeLeafKind: LF_ARGLIST (0x1201)
# NumArgs: 0
# Arguments [
# ]
# }
.byte 0x06, 0x00, 0x01, 0x12
.byte 0x00, 0x00, 0x00, 0x00
This should make debugging easier and testing more convenient.

A constant pool holding the address of a variable in equivalent to
a got entry. It produces exactly the same instruction sequence as a

Enforce compact branch register restrictions such as the use of the zero
register, both operands being the same register. Emit clear error in such
cases as the issue is subtle.
For bovc and bnvc, silently fixup such cases when emitting objects directly,
like LLVM started doing in rL269899.

The MachO export trie is a serially encoded trie keyed by symbol name. This code parses the trie and preserves the structure so that it can be dumped again.

The assumption, made in insert() that weak functions are always inserted after strong functions,
is only true in the first round of adding functions.
In subsequent rounds this is no longer guaranteed , because we might remove a strong function from the tree (because it's modified) and add it later,
where an equivalent weak function already exists in the tree.
This change removes the assert in insert() and explicitly enforces a weak->strong order.
This also removes the need of two separate loops in runOnModule().

Summary:
Creates a global variable containing preliminary information
for the cache-fragmentation tool runtime.
Passes a pointer to the variable (null if no variable is created) to the
compilation unit init and exit routines in the runtime.

Introduced in r271244, this is probably undefined behaviour and asserts when
compiled with Visual C++ debug mode.
On further note, the loop is quadratic with regard to the number of successors
since removeSuccessor is linear and could probably be modified to linear time.

This adds support to the backed to actually support SjLj EH as an exception
model. This is *NOT* the default model, and requires explicitly opting into it
from the frontend. GCC supports this model and for MinGW can still be enabled
via the `--using-sjlj-exceptions` options.

Since we already assert that the outgoing IR is in LCSSA, it is easy to
get misled into thinking that -indvars broke LCSSA if the incoming IR is
non-LCSSA. Checking this pre-condition will make such cases break in
more obvious ways.

This chapter demonstrates lazily JITing from ASTs with the expressions being
executed on a remote machine via a TCP connection. It needs some polish, but is
substantially complete.
Currently x86-64 SysV ABI (Darwin and Linux) only, but other architectures
can be supported by changing the server code to use alternative ABI support
classes from llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h.
