e4c36bd8fb Move r186044 tests into CodeGen/X86
I had thought that these tests could be target-neutral, but in practice this is
not the case (on some targets, like Hexagon and Darwin), they trigger an assert
(a different assert than the one that r186044 fixes).

initializer expressions, but instead crashes in AsmPrinter::EmitGlobalConstant.

6d75832312 Don't assert if we can't constant fold extract/insertvalue
A non-constant-foldable static initializer expression containing insertvalue or
extractvalue had been causing an assert:

  Constants.cpp:1971: Assertion `FC && "ExtractValue constant expr couldn't be
                                 folded!"' failed.

Now we report a more-sensible "Unsupported expression in static initializer"
error instead.

Fixes PR15417.

aae6843783 (1) Add ".test" to test/Other/lit.local.cfg, so llvm-cov.test is actually run.
(2) Rename llvm-cov test inputs so the string "llvm-cov" doesn't get
substituted by lit within the input filenames on the RUN line.
(3) XFAIL llvm-cov.test because it asserts:
include/llvm/ADT/SmallVector.h:140: reference llvm::SmallVectorTemplateCommon<llvm::GCOVBlock *, void>::operator[](unsigned int) [T = llvm::GCOVBlock *]: Assertion `begin() + idx < end()' failed.

c24a74205b IR: Don't constant fold GEP bitcasts between different address spaces
PR15262 reported a bug where the following instruction:

  i8 getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to i8*),
                                i32 2

was getting folded into:

  addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf, i32 0,
                                        i32 2)

This caused instcombine to crash because the original instruction and
the folded instruction have different types.  The issue was fixed by
disallowing bitcasts between different address spaces to be folded away.

76f7f4a33e Revert the series of commits starting with r166578 which introduced the
getIntPtrType support for multiple address spaces via a pointer type,
and also introduced a crasher bug in the constant folder reported in
PR14233.

These commits also contained several problems that should really be
addressed before they are re-committed. I have avoided reverting various
cleanups to the DataLayout APIs that are reasonable to have moving
forward in order to reduce the amount of churn, and minimize the number
of commits that were reverted. I've also manually updated merge
conflicts and manually arranged for the getIntPtrType function to stay
in DataLayout and to be defined in a plausible way after this revert.

Thanks to Duncan for working through this exact strategy with me, and
Nick Lewycky for tracking down the really annoying crasher this
triggered. (Test case to follow in its own commit.)

After discussing with Duncan extensively, and based on a note from
Micah, I'm going to continue to back out some more of the more
problematic patches in this series in order to ensure we go into the
LLVM 3.2 branch with a reasonable story here. I'll send a note to
llvmdev explaining what's going on and why.

Summary of reverted revisions:

r166634: Fix a compiler warning with an unused variable.
r166607: Add some cleanup to the DataLayout changes requested by
         Chandler.
r166596: Revert "Back out r166591, not sure why this made it through
         since I cancelled the command. Bleh, sorry about this!
r166591: Delete a directory that wasn't supposed to be checked in yet.
r166578: Add in support for getIntPtrType to get the pointer type based
         on the address space.

218ef13219 llvm-extract was unable to handle aliases. It would leave a copy on the
output of both

llvm-extract foo.ll -func=bar
and
llvm-extract foo.ll -func=bar -delete

so the two new files could not be linked together anymore. With this change
alias are handled almost like functions and global variables. Almost because
with alias we cannot just clear the initializer/body, we have to create a new
declaration and replace the alias with it.

The net result is that now the output of the above commands can be linked
even if foo.ll has aliases.

45a436ffcb Change the way the lint sanity checking pass detects misaligned memory accesses.
Previously it was only be able to detect problems if the pointer was a numerical
value (eg inttoptr i32 1 to i32*), but not if it was an alloca or globa.  The
reason was the use of ComputeMaskedBits: imagine you have "alloca i8, align 2",
and ask ComputeMaskedBits what it knows about the bits of the alloca pointer.
It can tell you that the bottom bit is known zero (due to align 2) but it can't
tell you that bit 1 is known one.  That's because the address could be an even
multiple of 2 rather than an odd multiple, eg it might be a multiple of 4.  Thus
trying to use KnownOne is ineffective in the case of an alloca as it will never
have any bits set.  Instead look explicitly for constant offsets from allocas
and globals.

5d3a0ce4e5 Fix the remaining TCL-style quotes found in the testsuite. This is
another mechanical change accomplished though the power of terrible Perl
scripts.

I have manually switched some "s to 's to make escaping simpler.

While I started this to fix tests that aren't run in all configurations,
the massive number of tests is due to a really frustrating fragility of
our testing infrastructure: things like 'grep -v', 'not grep', and
'expected failures' can mask broken tests all too easily.

Essentially, I'm deeply disturbed that I can change the testsuite so
radically without causing any change in results for most platforms. =/

d200829a4f Convert the uses of '|&' to use '2>&1 |' instead, which works on old
versions of Bash. In addition, I can back out the change to the lit

will be a few straggling issues.

eafc1e5909 The built-in shell test runner for some reason doesn't like the quoting
and multi-line nature of this test. I don't really feel like bugging
this kind of edge-case, so just put it on one line and use single
quotes. With this, every test *really* passes with the built-in shell
test runner.

8a358b3669 Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]

6bc19df503 Teach the 'opt' tool about '-Os' and '-Oz', corresponding to the Clang
options, to enable easier testing of the innards of LLVM that are
enabled by such optimization strategies.

Note that this doesn't provide the (much needed) function attribute
support for -Oz (as opposed to -Os), but still seems like a positive
step to better test the logic that Clang currently relies on.

a72b2f97a6 Use ConstantExpr::getExtractElement when constant-folding vectors
instead of getAggregateElement. This has the advantage of being
more consistent and allowing higher-level constant folding to
procede even if an inner extract element cannot be folded.

Make ConstantFoldInstruction call ConstantFoldConstantExpression
on the instruction's operands, making it more consistent with 
ConstantFoldConstantExpression itself. This makes sure that
ConstantExprs get TargetData-aware folding before being handed
off as operands for further folding.

This causes more expressions to be folded, but due to a known
shortcoming in constant folding, this currently has the side effect
of stripping a few more nuw and inbounds flags in the non-targetdata
side of constant-fold-gep.ll. This is mostly harmless.

This fixes rdar://11324230.

* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions.
