Quentin Colombet 4ff3cfb673 [X86] Make sure it is safe to clobber EFLAGS, if need be, when choosing
the prologue.

Do not use basic blocks that have EFLAGS live-in as prologue if we need
to realign the stack. Realigning the stack uses AND instruction and this
clobbers EFLAGS.

An other alternative would have been to save and restore EFLAGS around
the stack realignment code, but this is likely inefficient.

Fixes PR27531.

Richard Smith d49941b726 PR27513: When determining which declaration to put into an exported lookup
table for a module / PCH, never map from a normal declaration of a class to an
injected-class-name declaration (or vice versa). Those declarations live in
distinct lookup tables and should not be confused.

We really shouldn't be using a CXXRecordDecl to represent an
injected-class-name in the first place; I've filed PR27532 so we don't forget.

Philip Reames f105db4fc3 [LVI] Cut short search if we know we can't return a useful result
Previously we were recursing on our operands for unary and binary operators regardless of whether we knew how to reason about the operator in question.  This has the effect of doing a potentially large amount of work, only to throw it away.  By checking whether the operation is one LVI can handle, we can cut short the search and return the (overdefined) answer more quickly.  The quality of the results produced should not change.

Philip Reames 053c2a6f25 [LVI] Apply transfer rule for overdefine inputs for binary operators
As pointed out by John Regehr over in http://reviews.llvm.org/D19485, LVI was being incredibly stupid about applying its transfer rules.  Rather than gathering local facts from the expression itself, it was simply giving up entirely if one of the inputs was overdefined.  This greatly impacts the precision of the overall analysis and makes it far more fragile as well.

This patch builds on 267609 which did the same thing for unary casts.

Philip Reames e5030e85ea [LVI] A better fix for the assertion error introduced by 267609
Essentially, I was using the wrong size function.  For types which were sized, but not primitive, I wasn't getting a useful size for the operand and failed an assert.  I fixed this, and also added a guard that the input is a sized type.  Test case is for the original mistake.  I'm not sure how to actually exercise the sized type check.

As pointed out by John Regehr over in http://reviews.llvm.org/D19485, LVI was being incredibly stupid about applying its transfer rules. Rather than gathering local facts from the expression itself, it was simply giving up entirely if one of the inputs was overdefined.

This patch implements only the unary operation case. Once this is in, I'll implement the same for the binary operations.

r267556 made backslashes escape the next character
unconditionally in rsp files.  This test echos a path into

it's not important for this test to get the filename from

Rui Ueyama 673b609586 Handle Windows drive letters and ".." for --reproduce.
When --reproduce <path> is given, then we need to concatenate input
file paths to the given path to save input files to the directory.
Previously, path concatenation didn't handle Windows drive letters
so it could generate invalid paths such as "C:\D:\foo". It also didn't
handle ".." path components, so it could produce some bad paths
such as "foo/../../etc/passwd".

In this patch, Windows drive letters and ".." are removed before
concatenating paths.

Zachary Turner 53a65ba5c9 Parse and dump PDB DBI Stream Header Information
The DBI stream contains a lot of bookkeeping information for other
streams. In particular it contains information about section contributions
and linked modules. This patch is a first attempt at parsing some of the
information out of the DBI stream. It currently only parses and dumps the
headers of the DBI stream, so none of the module data or section
contribution data is pulled out.

This is just a proof of concept that we understand the basic properties of
the DBI stream's metadata, and followup patches will try to extract more
detailed information out.
