This also provides isConst/Volatile/Restrict on FunctionTypes to coalesce
the implementation with other callers (& update those other callers).

Patch contributed by Sam Panzer (panzer@google.com).

We've switched to a 3-component version numbering scheme for Apple releases,
and with this scheme, the final number is the one most relevant for setting
LLVM_MINOR_VERSION.  <rdar://problem/12071459>

No changes to these patches, MRI needed to be notified when changing
uses into defs and vice versa.

llvm-svn: 161644

This was the cause of the buildbot failures.

llvm-svn: 161642

This new attribute is intended to be used by the backend to determine how
the inline asm string should be parsed/printed. This patch adds the 
ia_nsdialect attribute and also adds a test case to ensure the IR is
correctly parsed, but there is no functional change at this time.

The standard dialect is assumed to be AT&T.  Therefore, this attribute
should only be added to MS-style inline assembly statements, which use
the Intel dialect.  If we ever support more dialects we'll need to
add additional state to the attribute.

These commits broke a number of buildbots.

llvm-svn: 161640

Forgot to check in this file.  Oops!

llvm-svn: 161639

Add 'watchpoint command add/delete/list' to lldb, plus two .py test files.

llvm-svn: 161638

Both methods need to clear out existing bindings and provide a new default
binding. Originally KillStruct always provided UnknownVal as the default,
but it's allowed symbolic values for quite some time (for handling returned
structs in C).

No functionality change.

llvm-svn: 161637

This should speed up activities that need to access bindings by cluster,
such as invalidation and dead-bindings cleaning. In some cases all we save
is the cost of building the region cluster map, but other times we can
actually avoid traversing the rest of the store.

In casual testing, this produced a speedup of nearly 10% analyzing SQLite,
with /less/ memory used.

llvm-svn: 161636

This makes it faster to access and invalidate bindings with symbolic offsets
by only computing this information once.

No intended functionality change.

llvm-svn: 161635

This makes it possible to speed up def_iterator by stopping at the first
use. This makes def_empty() and getUniqueVRegDef() much faster when
there are many uses.

In a +Asserts build, LiveVariables is 100x faster in one case because
getVRegDef() has an assertion that would scan to the end of a
def_iterator chain.

Spill weight calculation is significantly faster (300x in one case)
because isTriviallyReMaterializable() calls MRI->isConstantPhysReg(%RIP)
which calls def_empty(%RIP).

llvm-svn: 161634

Use a more conventional doubly linked list where the Prev pointers form
a cycle. This means it is no longer necessary to adjust the Prev
pointers when reallocating the VRegInfo array.

The test changes are required because the register allocation hint is
using the use-list order to break ties.

llvm-svn: 161633

Register MachineOperands are kept in linked lists accessible via MRI's
reg_iterator interfaces. The linked list management was handled partly
by MachineOperand methods, partly by MRI methods.

Move all of the list management into MRI, delete
MO::AddRegOperandToRegInfo() and MO::RemoveRegOperandFromRegInfo().

Be more explicit about handling the cases where an MRI pointer isn't
available.

llvm-svn: 161632

This was triggering -Woverloaded-virtual, but there's really no reason for
the cast version to be virtual anyway. It just calls through to the QualType
entry point.

llvm-svn: 161631

llvm-svn: 161630

Should fix the failures seen on some linux builders.

llvm-svn: 161629

the register info for getEncodingValue. This builds on the
small patch of yesterday to set HWEncoding in the register
file.

One (deprecated) use was turned into a hard number to avoid
needing register info in the old JIT.

llvm-svn: 161628

No test case, the crash only happens when the default use list order is
changed.

llvm-svn: 161627

llvm-svn: 161626

Added back member initialization for m_batch_command_mode, which was most likely removed accidentally a while back.
The consequence occurred recently probably due to our swicth to build with c++11.
This fixed 3 test failures.

llvm-svn: 161625

This new API will be used by clang to parse ms-style inline asms.

One goal of this project is to use this style of inline asm for targets other
then x86.  Therefore, this API needs to be implemented for non-x86 targets at
some point in the future.

<rdar://problem/11578397> Adding a new --summary-string option for the frame variable command which allows the user to provide a summary string with which he wants to display the variables without having to make a named summary first

llvm-svn: 161623

llvm-svn: 161622

An ASTContext's RecordLayoutInfo can only be used to look up offsets of
direct base classes, and we need the offset to make non-symbolic bindings
in RegionStore. This change makes sure that we have one layer of
CXXBaseObjectRegion for each base we are casting through.

This was causing crashes on an internal buildbot.

I thought. ;] Should let the bots make forward progress.

anyways. Also place it after the config makefile inclusion which seems
the more canonical location.

rebuilds to serially link each tool, which is really really slow.

We still have to build libclang serially first because c-index-test
depends on it.

should be used here.
