Previous versions of MSVC 2013 would miscompile ASTMatchers (and/or their
tests). Bump up the requirement and make sure we know about the minor
revision.
Minimum required version found by Michael Edwards!

If an EH table is printed in between the function and the jump table we would
fail to switch back to the text section to print the jump table.
llvm-svn: 229580
Add missing specialized node overloads for `MDNode::clone()` (they were
on most of the node types already, but missing from the others).
`MDNode::clone()` returns `TempMDNode` (`std::unique_ptr<MDNode,...>`),
while `TempMDSubrange::clone()` (for example) returns the more
convenient `TempMDSubrange` (`std::unique_ptr<TempMDSubrange,...>`).
llvm-svn: 229579
Previously `DwarfExpression::AddExpression()` relied on
default-constructing the end iterators for `DIExpression` -- once the
operands are represented explicitly via `MDExpression` (instead of via
the strange `StringRef` navigator in `DIHeaderIterator`) this won't
work. Explicitly take an iterator for the end of the range.

with the Mach-O S_LITERAL_POINTERS section type.
Also fix the printing of the leading addresses for literal sections to be consistent and
not print the 0x prefix. Updated test cases to match.
llvm-svn: 229548
This time we use a helper to format the assertion so we can just use
ASSERT_TRUE instead of relying on ASSERT_EQ being able to deal with
conversions between enum types.
This reverts r229496, re-applying r229473.
llvm-svn: 229547
Add support for having multiple sections with the same name and comdat.
Using this in combination with -ffunction-sections allows LLVM to output a .o
file with mulitple sections named .text. This saves space by avoiding long
unique names of the form .text.<C++ mangled name>.

Original message:
Invert the section relocation map.
It now points from rel section to section. Use it to set sh_info, avoiding
a brittle name lookup.
llvm-svn: 229539
Change the memory operands in sse12_fp_packed_scalar_logical_alias from scalars to vectors.
That's what the hardware packed logical FP instructions define: 128-bit memory operands.
There are no scalar versions of these instructions...because this is x86.
Generating the wrong code (folding a scalar load into a 128-bit load) is still possible
using the peephole optimization pass and the load folding tables. We won't completely
solve this bug until we either fix the lowering in fabs/fneg/fcopysign and any other
places where scalar FP logic is created or fix the load folding in foldMemoryOperandImpl()
to make sure it isn't changing the size of the load.

There was no reason to keep this private in config.h, and users
requested that it be available in PR22615.
Also fix a bug where patch versions of '0' would cause the macro to
remain undefined. The "#cmakedefine" command only creates a macro if the
named variable would be considered true in the context of an if().
llvm-svn: 229529
initialization. Initialize the subtarget once per function and
migrate Emit{Start|End}OfAsmFile to either use attributes on the
TargetMachine or get information from the subtarget we'd use
for assembling. One bit (getISAEncoding) touched the general
AsmPrinter and the debug output. Handle this one by passing
the function for the subprogram down and updating all callers
and users.
The top-level-ness of the ARM attribute output for assembly is,
by nature, contrary to how we'd want to do this for an LTO
situation where we have multiple cpu architectures so this
solution is good enough for now.

The 64-bit MIPS ELF archive file format is used by MIPS64 targets.
The main difference from a regular archive file is the symbol table format:
1. ar_name is equal to "/SYM64/"
2. number of symbols and offsets are 64-bit integers
http://techpubs.sgi.com/library/manuals/4000/007-4658-001/pdf/007-4658-001.pdf
Page 96
The patch allows reading of such archive files by llvm-nm, llvm-objdump
and other tools. But it does not support archive files with number of symbols
and/or offsets exceed 2^32. I think it is a rather rare case requires more
significant modification of `Archive` class code.

This is a follow-on patch to:
http://reviews.llvm.org/D7093
That patch canonicalized constant splats as build_vectors,
and this patch removes the constant check so we can canonicalize
all splats as build_vectors.
This fixes the 2nd test case in PR22283:

The unfortunate code duplication between SelectionDAG and DAGCombiner
is discussed in the earlier patch review. At least this patch is just
removing code...
This improves an existing x86 AVX test and changes codegen in an ARM test.

The problem was in store-sink barrier check.
Store sink barrier should be checked for ModRef (read-write) mode.

Flag -fast-isel-abort is required in order to verify that X86FastISel
never fails to select FPExt (float-to-double) and FPTrunc (double-to-float).
No Functional change intended.
llvm-svn: 229489
GCC 4.8 reported two new warnings due to comparisons
between signed and unsigned integer expressions. The new warnings were
accidentally introduced by revision 229480.
Added explicit casts to silence the warnings. No functional change intended.
llvm-svn: 229488
This added API to the InstrProfWriter to write to a string so I could
write unittests without using temp files. This doesn't really work,
since the format has tighter alignment requirements than a char.
This reverts r229478 and its follow-up, r229481.
llvm-svn: 229483
- added mask types v8i1 and v16i1 to possible function parameters
- enabled passing 512-bit vectors in standard CC
- added a test for KNL intel_ocl_bi conventions
llvm-svn: 229482
Vector zext tends to get legalized into a vector anyext, represented as a vector shuffle with an undef vector + a bitcast, that gets ANDed with a mask that zeroes the undef elements.
Combine this into an explicit shuffle with a zero vector instead. This allows shuffle lowering to match it as a zext, instead of matching it as an anyext and emitting an explicit AND.
This combine only covers a subset of the cases, but it's a start.
