Alexey Samsonov 7a36e6126b [Sanitizer] Refactor symbolization interface: use class instead of several functions. Move some code around to get rid of extra source files

Renato Golin 74c652eb3f Adding LZMA as dep for XML2 on 2.8.0 or higher
LibXML2 config doesn't specify lzma as a dependency, which breaks
cross-compilation builds using new linkers (ld 2.21 or higher).

There is a bug on libxml2 to fix that, but since it's going to take
a while for things to go round and back, so we should have a harmless
addition of the library until then.

Richard Sandiford a9eb9972e4 [SystemZ] Add TM and TMY
The main complication here is that TM and TMY (the memory forms) set
CC differently from the register forms.  When the tested bits contain
some 0s and some 1s, the register forms set CC to 1 or 2 based on the
value the uppermost bit.  The memory forms instead set CC to 1
regardless of the uppermost bit.

Until now, I've tried to make it so that a branch never tests for an
impossible CC value.  E.g. NR only sets CC to 0 or 1, so branches on the
result will only test for 0 or 1.  Originally I'd tried to do the same
thing for TM and TMY by using custom matching code in ISelDAGToDAG.
That ended up being very ugly though, and would have meant duplicating
some of the chain checks that the common isel code does.

I've therefore gone for the simpler alternative of adding an extra
operand to the TM DAG opcode to say whether a memory form would be OK.
This means that the inverse of a "TM;JE" is "TM;JNE" rather than the
more precise "TM;JNLE", just like the inverse of "TMLL;JE" is "TMLL;JNE".
I suppose that's arguably less confusing though...

Stepan Dyatkovskiy f16ade7604 Fix for PR16752. Second commit.
PR16752: 'mode' attribute for unusual targets doesn't work properly
Description:
Troubles could be happened due to some assumptions in handleModeAttr function (see SemaDeclAttr.cpp).
For example, it assumes that 32 bit integer is 'int', while it could be 16 bit only.
Instead of asking target: 'which type do you want to use for int32_t ?' it just hardcodes general opinion. That doesn't looks pretty correct.
Please consider the next solution:
1. In Basic/TargetInfo add getIntTypeByWidth and getRealTypeByWidth methods. Methods asks target for proper type for given bit width.
2. Fix handleModeAttr according to new methods in TargetInfo.

Fixes:
1st Commit (Done): Add new methods for TargetInfo:
     getRealTypeByWidth and getIntTypeByWidth
  for ASTContext names are almost same(invokes new methods from TargetInfo):
     getIntTypeForBitwidth and getRealTypeForBitwidth

2nd Commit (Current): Fix SemaDeclAttr, handleModeAttr function.

Michael Gottesman f125e00e37 [python bindings] Added code to get the length of a memory buffer. Tests are included.
This is a part of a series of patches that have been sitting fallow on a
personal branch that I have been messing with for a bit.

The patches start to flesh out the python llvm-c wrapper to the point where you can:

1. Load Modules from Bitcode/Dump/Print them.
2. Iterate over Functions from those modules/get their names/dump them.
3. Iterate over the BasicBlocks from said function/get the BB's name/dump it.
4. Iterate over the Instructions in said BasicBlocks/get the instructions
   name/dump the instruction.

My main interest in developing this was to be able to gather statistics about
LLVM IR using python scripts to speed up statistical profiling of different IR
level transformations (hence the focus on printing/dumping/getting names).

This is a gift from me to the LLVM community = ).

I am going to be committing the patches slowly over the next bit as I have time
to prepare the patches.

The overall organization follows the c-api like the bindings that are already
implemented.

Eli Friedman 5ef2175866 Make -Wunused warning rules more consistent.
This patch does a few different things.

This patch improves unused var diags for const vars: we no longer
unconditionally suppress diagnostics for const vars, instead only suppressing
the diagnostic when the declaration appears to be useful.

This patch also makes us more consistently use whether a variable/function
is declared in the main file to suppress diagnostics where appropriate.

Jim Ingham df0ae22f92 Changing the default shell to /bin/sh brought up a long-standing bug on OS X,
that /bin/sh re-exec's itself to /bin/bash, so it needs one more resume when you
are using it as the shell than /bin/bash did or you will stop at the start of your
program, rather than running it.

So I added a Platform API to get the number of resumes needed when launching with
a particular shell, and set the right values for Mac OS X.

"coalesce the line ranges for a file & line breakpoint to the first range in each block".  We were still setting a silly number
of independent breakpoints sometimes, and until we get a compiler that emits trustworthy is_stmt flags in the line table, we
need to do something to reduce the noise.

Reid Kleckner 76808056f9 Ignore calling conventions when checking function template specializations
Summary:
Calling conventions are inherited during decl merging.  Before this
change, deduction would fail due to a type mismatch between the template
and the specialization.  This change adjusts the CCs to match before
deduction, and lets the decl merging logic diagnose mismatch or inherit
the CC from the template.

This allows specializations of static member function templates in the
Microsoft C++ ABI.

Matt Arsenault d232222f34 Don't use getSetCCResultType for creating a vselect
The vselect mask isn't a setcc.

This breaks in the case when the result of getSetCCResultType
is larger than the vector operands

e.g. %tmp = select i1 %cmp <2 x i8> %a, <2 x i8> %b
when getSetCCResultType returns <2 x i32>, the assertion
that the (MaskTy.getSizeInBits() == Op1.getValueType().getSizeInBits())
is hit.

No test since I don't think I can hit this with any of the current
targets. The R600/SI implementation would break, since it returns a
vector of i1 for this, but it doesn't reach ExpandSELECT for other
reasons.

Andrew Trick e1f7bf2c02 mi-sched: smooth out the cyclicpath heuristic.
Arnold's idea.

I generally try to avoid stateful heuristics because it can make
debugging harder. However, we need a way to prevent the latency
priority from dominating, and it somewhat makes sense to schedule
aggressively for latency only within an issue group.

Swift in particular likes this, and it doesn't hurt anyone else:
