b1058310c1 [mips] Distinguish 'R', 'ZC', and 'm' inline assembly memory constraint.
Summary:
Previous behaviour of 'R' and 'm' has been preserved for now. They will be
improved in subsequent commits.

The offset permitted by ZC varies according to the subtarget since it is
intended to match the restrictions of the pref, ll, and sc instructions.

The restrictions on these instructions are:
* For microMIPS: 12-bit signed offset.
* For Mips32r6/Mips64r6: 9-bit signed offset.
* Otherwise: 16-bit signed offset.

a54c5b4489 "float2int": Add a new pass to demote from float to int where possible.
It is possible to have code that converts from integer to float, performs operations then converts back, and the result is provably the same as if integers were used.

This can come from different sources, but the most obvious is a helper function that uses floats but the arguments given at an inlined callsites are integers.

This pass considers all integers requiring a bitwidth less than or equal to the bitwidth of the mantissa of a floating point type (23 for floats, 52 for doubles) as exactly representable in floating point.

To reduce the risk of harming efficient code, the pass only attempts to perform complete removal of inttofp/fptoint operations, not just move them around.

d3ab717935 Use std::bitset for SubtargetFeatures
Previously, subtarget features were a bitfield with the underlying type being uint64_t. 
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.

The first time this was committed (r229831), it caused several buildbot failures. 
At least some of the ARM ones were due to gcc/binutils issues, and should now be fixed.

fa17ce8b6e [SelectionDAG] Fixed issue with uitofp vector constant folding being treated as sitofp
While the uitofp scalar constant folding treats an integer as an unsigned value (from lang ref):

%X = sitofp i8 -1 to double ; yields double:-1.0
%Y = uitofp i8 -1 to double ; yields double:255.0

The vector constant folding was always using sitofp:

%X = sitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0>
%Y = uitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0>

This patch fixes this so that the correct opcode is used for sitofp and uitofp.

%X = sitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double -1.0, double -1.0>
%Y = uitofp <2 x i8> <i8 -1, i8 -1> to <2 x double> ; yields <double 255.0, double 255.0>

7ad96398c6 DebugInfo: Overload get() in DIDescriptor subclasses
Continue to simplify the `DIDescriptor` subclasses, so that they behave
more like raw pointers.  Remove `getRaw()`, replace it with an
overloaded `get()`, and overload the arrow and cast operators.  Two
testcases started to crash on the arrow operators with this change
because of `scope:` references that weren't real scopes.  I fixed them.
Soon I'll add verifier checks for them too.

This also adds explicit dereference operators.  Previously, the builtin
dereference against `operator MDNode *()` would have worked, but now the
builtins are ambiguous.

dce96380c1 Cleanup else-after-return and add an early-return to llvm-nm
The loop and error handling in checkMachOAndArchFlags didn't make sense
to me (a loop that only ever executes once? An error path that uses the
element the loop stopped at (which must always be a buffer overrun if
I'm reading that right?)... I'm confused) but I've made a guess at what
was intended.

Based on a patch by Richard Thomson to simplify boolean expressions.

c9ad3ab624 [AArch64, ARM] Enable GlobalMerge with -O3 rather than -O1.
The pass used to be enabled by default with CodeGenOpt::Less (-O1).
This is too aggressive, considering the pass indiscriminately merges
all globals together.

Currently, performance doesn't always improve, and, on code that uses
few globals (e.g., the odd file- or function- static), more often than
not is degraded by the optimization.  Lengthy discussion can be found
on llvmdev (AArch64-focused;  ARM has similar problems):
  http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-February/082800.html
Also, it makes tooling and debuggers less useful when dealing with
globals and data sections.

GlobalMerge needs to better identify those cases that benefit, and this
will be done separately.  In the meantime, move the pass to run with
-O3 rather than -O1, on both ARM and AArch64.

07118a3546 Re-land: Generate targets for each lit suite.
Summary:
This change makes CMake scan for lit suites and generate a target for each lit test suite. The targets follow the format check-<project>-<suite path>.

For example:
check-llvm-unit - Runs the LLVM unit tests
check-llvm-codegen-arm - Runs the ARM codeine tests

Note: These targets are not generated during multi-configuration generators (i.e. Xcode and Visual Studio) because target clutter impacts UI usability.

* Also fixed a minor issue that Duncan pointed out to me I was passing the suite to lit twice

59a5e979b5 R600/SI: Allow commuting compares
This enables very common cases to switch to the
smaller encoding.

All of the standard LLVM canonicalizations of comparisons
are the opposite of what we want. Compares with constants
are moved to the RHS, but the first operand can be an inline
immediate, literal constant, or SGPR using the 32-bit VOPC
encoding.

There are additional bad canonicalizations that should
also be fixed, such as canonicalizing ge x, k to gt x, (k + 1)
if this makes k no longer an inline immediate value.

c71d3d47a0 Refactor: simplify boolean expressions in llvm-objdump
Simplify boolean expressions involving `true` and `false` with `clang-tidy`.

Actually upon inspection a bunch of these boolean variables could be
factored away entirely anyway - using find_if and then testing the
result before using it. This also helps reduce indentation in the code
anyway - and a bunch of other related simplification fell out nearby so
I just committed all of that.

a75fecc370 Revert "[ARM] Add more pattern matching for f16 <-> f64 conversions"
This change is incorrect since it converts double rounding into single rounding,
which can produce different results. Instead this optimization will be done by
modifying Clang's codegen to not produce double rounding in the first place.

This reverts commit r232954.

2f729838f1 [ARM] Remove target-specific ITOFP/FPTOI nodes
Anton tried this 5 years ago but it was reverted due to extra VMOVs
being emitted. This can be easily fixed with a liberal application
of patterns - matching loads/stores and extractelts.
