[mips][msa] Added support for matching bset, bseti, bneg, and bnegi from normal IR (i.e. not intrinsics)

llvm-svn: 194469

This is a workaround for clang-format bug (PR17874).

[mips][msa] Change constant used in ori tests to avoid conflict with bseti (also xori to avoid bnegi)

Upcoming commit(s) are going to add support for bseti and bnegi. This would
cause some existing tests to (correctly) change behaviour and emit a different
instruction. This patch prevents this by changing the constant used in ori and
xori tests so that they will not be matchable by the bseti and bnegi patterns
when these instructions are matchable from normal IR.

ATOMIC_FENCE is lowered to a compiler barrier which is codegen only. There
is no need to emit an instructions since the XCore provides sequential
consistency.

Original patch by Richard Osborne

llvm-svn: 194463

The xcore llvm backend does not handle 8 byte alignment viz:
  "%BadAlignment = alloca i64, align 8"
So getPreferredTypeAlign() must never overalign.

Change SizeType, PtrDiffType, IntPtrType, WCharType, WIntType
to follow the XMOS llvm-gcc front end's settings.

Replace std::map with SmallVector to memorize the cached result since SCEV usually belongs to little Loop/BB
Linear scan on SmallVector is faster than std::map.

This reverts commit r194451.

Not sure why the tests are failing on the buildbot. They run fine on my
local machine. Could it possibly be because of the endianness of the
architectures? The GCNO and GCDA files are little-endian encoded, and
llvm-cov expects it to remain that way. Is this a safe assumption?

llvm-svn: 194454

Also updated test files that were generated from this change.

llvm-svn: 194453

The original decls are created when used. The replacements are created at the
end of the TU in reverse order.

This makes the original order far better for testing. This is particularly
important since the replacement logic could be used even when
-mconstructor-aliases is not used, but that would make many tests hard to read.

This is a fixed version of r194357 which handles replacing a destructor with
another which is an alias to a third one.

llvm-svn: 194452

This test compares the output of llvm-cov against a coverage file
generated by gcov. Since the source file must be in the current
directory when reading GCNO files, the test will first cd into the
Inputs directory.

See http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-November/033369.html for discussion on cfe-dev.

This fix explicitly checks whether we are within the declcontext of a lambda's call operator - which is what I had intended to be true (and assumed would be true if getCurLambda returns a valid pointer) before checking whether a lambda can capture the potential-captures of the innermost lambda.

A deeper fix (that addresses why getCurLambda() returns a valid pointer when perhaps it shouldn't?) - as proposed by Richard Smith in http://llvm.org/bugs/show_bug.cgi?id=17877 - has been suggested as a FIXME.

Patch was LGTM'd by Richard (just barely :)

Fixed moduleImport and ident callbacks.  Fixed modules test. Added ident callback test.  A better test for moduleExport is coming.

substitution failure, allow a flag to be set on the Diagnostic object,
to mark it as 'causes substitution failure'.

Refactor Diagnostic.td and the tablegen to use an enum for SFINAE behavior
rather than a bunch of flags.

llvm-svn: 194444

Print the range of registers used with a single letter prefix.
This better matches what the shader compiler produces and
is overall less obnoxious than concatenating all of the
subregister names together.

Instead of SGPR0, it will print s0. Instead of SGPR0_SGPR1,
it will print s[0:1] and so on.

There doesn't appear to be a straightforward way
to get the actual register info in the InstPrinter,
so this parses the generated name to print with the
new syntax.

The required test changes are pretty nasty, and register
matching regexes are now worse. Since there isn't a way to
add to a variable in FileCheck, some of the tests now don't
check the exact number of registers used, but I don't think that
will be a real problem.

llvm-svn: 194443

This has no material effect at this time since we don't have a direct
object emitter for mips16 and the assembler can't tell them apart. I
place a comment "16 bit inst" for those so that I can tell them apart in the
output. The constant island pass has only been minimally changed to allow
this. More complete branch work is forthcoming but this is the first
step.

Hopefully Richard won't notice this terrible egregiocity - clearly the work of a malevolent poltergeist - fixed now ;)

No functionality change.

No Functionality change.

This refactoring avoids having to call getCurLambda right after PushLambdaScope, to obtain the LambdaScopeInfo that was created during the call to PushLambdaScope. 

llvm-svn: 194438

The parsing method still returns llvm::error_code for consistency with
other parsing methods.  Minor cleanup, no functionality change.

X86AsmPrinter::EmitInstruction, rather than X86MCInstLower::Lower.

The aim is to improve the reusability of the X86MCInstLower class by making it
more function-like. The X86::MORESTACK_RET_RESTORE_R10 pseudo broke the
function model by emitting an extra instruction to the MCStreamer attached to
the AsmPrinter.

The patch should have no impact on generated code.
