Greg Clayton f8712de58c Since we are having issues with the new LLVM MC disassembler, we can have
them both installed with the LLVM MC version being the default. I renamed the
name of the LLVM MC disassembler plug-in to "llvm-mc" and the LLVM enhanced
disassembly plug-in to "llvm-edis" and they can both be installed for now.

To use the "llvm-edis" disassembler, you can just specify it while disassembling:

(lldb) disassemble --plugin llvm-edis --name main
(lldb) disassemble --plugin llvm-mc --name main

This will allow us to compare the output of the two disassembler and eventually
deprecate the old one when the new one is ready. But it does use the new disassembler
by default so we continue to test it on a daily basis.

Chad Rosier 6a63a74113 [fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271%
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester.
This may also improve compile-time on architectures that would otherwise 
generate a libcall for urem (e.g., ARM) or fall back to the DAG selector.

Johnny Chen 7cb09b61b2 WIP snapshot of hardware watchpoints for arm. A simple watchpoint has triggered.
However, the debugserver cannot get past the instruction which triggered the watchpoint.
So a workaround is in place for the time being which disables the triggered watchpoint
before resuming.

Lots of commented out printf's remain in the source which needs to be cleaned up.

Richard Trieu ba4d0871f7 Change the binary operator data recursive evaluator to not stop at the first
non-constant value encountered.  This allows the evaluator to deduce that
expressions like (x < 5 || true) is equal to true.  Previously, it would visit
x and determined that the entire expression is could not evaluated to a
constant.

This fixes PR12318.

Nico Weber d998e8450e Add a ${pathsep} variable to lit that expands to : (or ; on win32).
This is in braces so that it doesn't conflict with the existing %p.
It uses braces instead of parens because parens would have to be
regex-escaped.

Anna Zaks fc2e153444 [analyzer] Malloc: Utter the name of the leaked variable.
Specifically, we use the last store of the leaked symbol in the leak diagnostic.
(No support for struct fields since the malloc checker doesn't track those
yet.)

+ Infrastructure to track the regions used in store evaluations.
This approach is more precise than iterating the store to
obtain the region bound to the symbol, which is used in RetainCount
checker. The region corresponds to what is uttered in the code in the
last store and we do not rely on the store implementation to support
this functionality.

Jim Grosbach e13adc38d0 Checking a build_vector for an all-ones value.
Type legalization can zero-extend the elements of the build_vector node, so,
for example, we may have an <8 x i8> with i32 elements of value 255. That
should return 'true' for the vector being all ones.

Bob Wilson 7f05ca38e4 Duplicated code is bad. At least make it consistent.
The getARMTargetCPU and getLLVMArchSuffixForARM functions exist in both
Toolchain.cpp and Tools.cpp.  This stuff needs a thorough overhaul.  In the
meantime, this patch at least makes them consistent.  One version had been
converted to use StringSwitch, and the other version had new Cortex M-series
processors added.

Sean Callanan 8ce585f8f1 Added a local patch to reflect an LLVM fix for
relocations (LLVM revision 153147).  Now when
we report section locations in the target process,
LLVM will apply both those relocations whose
targets are in that section and those relocations
which reside in that section and point to other
sections.

Bob Wilson cc4ab9d9c0 For Darwin, do not let -mcpu override the -arch option. <rdar://11059238>
On Darwin the architecture and the corresponding Mach-O slice is typically
specified with -arch.  If not, it defaults to the current host architecture.
Do not use -mcpu to override the -arch value.  This is only an issue when
people need to use specialized code for a non-default CPU (hopefully guarded
by run-time checks to detect the current processor).  The -mcpu option is
still used for the -target-cpu option to clang, but this patch causes it to
not be used to set the architecture in the target triple.
