Bill Schmidt 6207a4b7dd Add artificial PRED_BAD to PPC::Predicate enumeration.
Allows returning a PPC::Predicate from a function with a no-predicate
value possible.  Preparatory patch for fast-isel on PPC64 ELF.  No
behavioral change intended.

Ulrich Weigand 32d725b80a [MC/DWARF] Support .debug_frame / .debug_line code alignment factors
I've been comparing the object file output of LLVM's integrated
assembler against the external assembler on PowerPC, and one
area where differences still remain are in DWARF sections.

In particular, the GNU assembler generates .debug_frame and
.debug_line sections using a code alignment factor of 4, since
all PowerPC instructions have size 4 and must be aligned to a
multiple of 4.  However, current MC code hard-codes a code
alignment factor of 1.

This patch changes this by adding a "minimum instruction alignment"
data element to MCAsmInfo and using this as code alignment factor.

This requires passing a MCContext into MCDwarfLineAddr::Encode
and MCDwarfLineAddr::EncodeAdvanceLoc.  Note that one caller,
MCDwarfLineAddr::Write, didn't actually have that information
available.  However, it turns out that this routine is in fact
never used in the whole code base, so the patch simply removes
it.  If it turns out to be needed again at a later time, it
could be re-added with an updated interface.

Akira Hatanaka 5c50a16ee0 [mips] Add an IR transformation pass that optimizes calls to sqrt.
The pass emits a call to sqrt that has attribute "read-none". This call will be
converted to an ISD::FSQRT node during DAG construction, which will turn into
a mips native sqrt instruction.

JF Bastien 3c6bb8e19f ARM FastISel fix sext/zext fold
Sign- and zero-extension folding was slightly incorrect because it wasn't checking that the shift on extensions was zero. Further, I recently added AND rd, rn, #255 as a form of 8-bit zero extension, and failed to add the folding code for it.

This patch fixes both issues.

This patch fixes both, and the test should remain the same:

Tobias Grosser bd9e549e21 Make host ARM CPU feature detection independent of the vendor
For ARM on linux we use /proc/cpuinfo to detect the host CPU's features.
Linux derives these values without ever looking at the vendor of the
specific CPU implementation. Hence, it adds little value, if we parse
the output of /proc/cpuinfo only for certain vendors.

This patch enables us to derive the correct feature flags e.g. for Qualcomm
CPUs.

Rafael Espindola a82555c0f8 Change how globalopt handles aliases in llvm.used.
Instead of a custom implementation of replaceAllUsesWith, we just call
replaceAllUsesWith and recreate llvm.used and llvm.compiler-used.

This change is particularity interesting because it makes llvm see
through what clang is doing with static used functions in extern "C"
contexts. With this change, running clang -O2 in

extern "C" {
  __attribute__((used)) static void foo() {}
}

produces

@llvm.used = appending global [1 x i8*] [i8* bitcast (void ()* @foo to
i8*)], section "llvm.metadata"
define internal void @foo() #0 {
entry:
  ret void

It will be tested in the next commit which moves another user to identify_magic.

Original message:

Fix an out of bounds array access.

We were looking at Magic[5] without checking Length. Since this path would not
return unless Length >= 18 anyway, just move the >= 18 check up.

Rafael Espindola 70a729dfd5 Require members of llvm.used to be named.
The effect of llvm.used is to introduce an invisible reference, so this seems
a reasonable restriction. It will be used to provide an easy ordering of
the entries in llvm.used.

Mihai Popa 1c7be576c5 This patch adds support for FPINST/FPINST2 as operands to vmsr/vmrs. These are optional registers that may be supported some ARM implementations to aid with resolution of floating point exceptions. The manual pages for vmsr and vmrs do not detail their use. Encodings and other information can be found in ARM Architecture Reference Manual section F, chapter 6, paragraph 3.
