[lit] Add a test for the builtin config map.

Config map is not exposed through the command line, so testing this
is somewhat tricky.  But basically we need a test that if a custom
driver builds a config map and passes it to main, it gets respected.

A config map allows config files in the source tree to be mapped
to alternate config files in the build tree.  This particular test
works by having two config files in separate directories, and
setting up a config map to have that redirects A/lit.site.cfg
to B/altconfig.  Then, we print a message in A/lit.site.cfg
and B/altconfig and check that we do see the output from B
but don't see the output from A.  Additionally we test that
the test suite specified by A's config map is properly discovered.

[SROA] Really remove associated dbg.declare when removing dead alloca

Summary:
There already was code that tried to remove the dbg.declare, but that code
was placed after we had called
 I->replaceAllUsesWith(UndefValue::get(I->getType()));
on the alloca, so when we searched for the relevant dbg.declare, we
couldn't find it.

Now we do the search before we call RAUW so there is a chance to find it.

An existing testcase needed update due to this. Two dbg.declare with undef
were removed and then suddenly one of the two CHECKS failed.

Before this patch we got

  call void @llvm.dbg.declare(metadata i24* undef, metadata !14, metadata !DIExpression(DW_OP_LLVM_fragment, 32, 24)), !dbg !15
  call void @llvm.dbg.declare(metadata %struct.prog_src_register* undef, metadata !14, metadata !DIExpression()), !dbg !15
  call void @llvm.dbg.value(metadata i32 0, metadata !14, metadata !DIExpression(DW_OP_LLVM_fragment, 0, 32)), !dbg !15
  call void @llvm.dbg.value(metadata i32 0, metadata !14, metadata !DIExpression(DW_OP_LLVM_fragment, 32, 24)), !dbg !15

and with it we get

  call void @llvm.dbg.value(metadata i32 0, metadata !14, metadata !DIExpression(DW_OP_LLVM_fragment, 0, 32)), !dbg !15
  call void @llvm.dbg.value(metadata i32 0, metadata !14, metadata !DIExpression(DW_OP_LLVM_fragment, 32, 24)), !dbg !15

However, the CHECKs in the testcase checked things in a silly order, so
they only passed since they found things in the first dbg.declare. Now
we changed the order of the checks and the test passes.

[IR] Add llvm.dbg.addr, a control-dependent version of llvm.dbg.declare

Summary:
This implements the design discussed on llvm-dev for better tracking of
variables that live in memory through optimizations:
  http://lists.llvm.org/pipermail/llvm-dev/2017-September/117222.html

This is tracked as PR34136

llvm.dbg.addr is intended to be produced and used in almost precisely
the same way as llvm.dbg.declare is today, with the exception that it is
control-dependent. That means that dbg.addr should always have a
position in the instruction stream, and it will allow passes that
optimize memory operations on local variables to insert llvm.dbg.value
calls to reflect deleted stores. See SourceLevelDebugging.rst for more
details.

The main drawback to generating DBG_VALUE machine instrs is that they
usually cause LLVM to emit a location list for DW_AT_location. The next
step will be to teach DwarfDebug.cpp how to recognize more DBG_VALUE
ranges as not needing a location list, and possibly start setting
DW_AT_start_offset for variables whose lifetimes begin mid-scope.

[DebugInfo] Use a MapVector to coalesce MachineOperand locations

Summary:
The new code should be linear in the number of DBG_VALUEs, while the old
code was quadratic. NFC intended.

This is also hopefully a more direct expression of the problem, which is
to:

1. Rewrite all virtual register operands to stack slots or physical
   registers
2. Uniquely number those machine operands, assigning them location
   numbers
3. Rewrite all uses of the old location numbers in the interval map to
   use the new location numbers

In r313400, I attempted to track which locations were spilled in a
parallel bitvector indexed by location number. My code was broken
because these location numbers are not stable during rewriting.

Previously jaml2obj would segfault on empty document.
(without yaml description).

6 years ago[SLP] Vectorize jumbled memory loads.
Mohammad Shahid [Wed, 20 Sep 2017 08:18:28 +0000 (08:18 +0000)]
[SLP] Vectorize jumbled memory loads.

Summary:
This patch tries to vectorize loads of consecutive memory accesses, accessed
in non-consecutive or jumbled way. An earlier attempt was made with patch D26905
which was reverted back due to some basic issue with representing the 'use mask' of
jumbled accesses.

This patch fixes the mask representation by recording the 'use mask' in the usertree entry.
