The intrinsic calls are dropped, but the annotated value is propagated.

Fixes PR 15253

Original patch by Zeng Bin!

llvm-svn: 182387

Although I had added some support for the BDZ/BDNZ branches into the selector
(in r158204), I had not correctly adjusted the condition at the top of the
loop. As a result, these branches were still essentially unsupported.

This fixes PR16086. Unfortunately, any test case would be very large (because
it would need to force the loop backedge to exceed the range of the 16-bit
immediate).

This stuff is used on platforms where MSan does not have a proper VarArg
implementation (anything other than x86_64 at the moment).

llvm-svn: 182375

Removed SSEPacked domain from all forms (AVX, SSE, signed, unsigned) scalar compare instructions, like COMISS, COMISD.

Alternative fix for problem addressed in r182233

Revision r182233 partially reverted the change in r181200 to simplify
JIT unif test #ifdefs, because that change caused a link error on some
host operating systems where the export list requires the following
symbols to be defined:

 JITTest_AvailableExternallyFunction
 JITTest_AvailableExternallyGlobal

As discussed on the list, the commit reverts r182233 (and re-installs
the full r181200 change), and instead fixes the link problem by moving
those two symbols to the top of the file and unconditionally defining
them.

Otherwise we'll get a mix of signed and unsigned compares.
Fixes PR15977.

After r182274, the branches in these tests must always be short.

These were accidentally omitted.

This is to fix PR15408 where an undefined symbol Lline_table_start1 is used.
Since we do not generate the debug_line section when .loc is used,
Lline_table_start1 is not emitted and we can't refer to it when calculating
at_stmt_list for a compile unit.

pic calls. These need to be there so we don't try and use helper
functions when we call those.

As part of this, make sure that we properly exclude helper functions in pic
mode when indirect calls are involved.

"triples". Also remove the implication that they're only used for specifying a
target.

Describe that they are assigned numbered label using the same counter
as for unnamed temporaries.

This resolves the last of the PR14606 failures in the GDB 7.5 test
suite by implementing an optional name field for
DW_TAG_imported_modules/DIImportedEntities and using that to implement
C++ namespace aliases (eg: "namespace X = Y;").

By default, a teq instruction is inserted after integer divide. No divide-by-zero
checks are performed if option "-mnocheck-zero-division" is used.

Now that the preheader insertion logic in LoopSimplify is externally exposed,
use it, and remove the copy-and-pasted version.

No functionality change intended.

llvm-svn: 182300

Other passes, PPC counter-loop formation for example, also need to add loop
preheaders outside of the regular loop simplification pass. This makes
InsertPreheaderForLoop a global function so that it can be used by other
passes.

No functionality change intended.

[NVPTX] Fix mis-use of CurrentFnSym in NVPTXAsmPrinter.  This was causing a symbol name error in the output PTX.

As the pairing of this instruction form with the bdnz/bdz branches is now
enforced by the verification pass, make it clear from the name that these
are used only for counter-based loops.

No functionality change intended.

llvm-svn: 182296

When asserts are enabled, this adds a verification pass for PPC counter-loop
formation. Unfortunately, without sacrificing code quality, there is no better
way of forming counter-based loops except at the (late) IR level. This means
that we need to recognize, at the IR level, anything which might turn into a
function call (or indirect branch). Because this is currently a finite set of
things, and because SelectionDAG lowering is basic-block local, this can be
done. Nevertheless, it is fragile, and failure results in a miscompile. This
verification pass checks that all (reachable) counter-based branches are
dominated by a loop mtctr instruction, and that no instructions in between
clobber the counter register. If these conditions are not satisfied, then an
ICE will be triggered.

In short, this is to help us sleep better at night.

R600TextureIntrinsicsReplacer.cpp:232: warning: the address of ‘ArgsType’ will always evaluate as ‘true’

This doesn't have any effect on the output as a vararg intrinsic behaves the
same way as a non-vararg one.

llvm-svn: 182293

The -debug-only option is only available on asserts builds.

llvm-svn: 182291

This will simplify the instructions and also the pattern definitions.
