Dmitry Vyukov 816bf44ac6 tsan: reduce history size in Go mode
The ContainsSameAccess optimization substantially reduces pressure
on trace by eliminating duplicate accesses. So now we can reduce
default trace size to reduce per-goroutine memory consumption.
Current default size is 64K events, new -- 32K events.
In either case user can change it with GORACE env var.

Reduces per-goroutine memory consumption from 356K to 226K.

Jonathan Roelofs a61779e67a Modularize TargetInfo discovery in the lit config
When the remote execution patch lands, this will allow us to drop in a
replacement TargetInfo object for locale support discovery, alleviating
the assumption that host==target.

Ilia K 8f37ca56d6 Add -exec-arguments command
Summary:
This patch adds -exec-arguments command for lldb-mi. -exec-arguments command allows to specify arguments for executable file in MI mode. Also it contains tests for that command.

Btw, new added files was formatted by clang-format.

Andrea Di Biagio b14ae8692d [CodeGenPrepare] Removed duplicate logic. SimplifyCFG already knows how to speculate calls to cttz/ctlz.
SimplifyCFG now knows how to speculate calls to intrinsic cttz/ctlz that are
'cheap' for the target. Therefore, some of the logic in CodeGenPrepare
that was originally added at revision 224899 can now be removed.

This patch is basically a no functional change. It removes the duplicated
logic in CodeGenPrepare and converts all the existing target specific tests
for cttz/ctlz into SimplifyCFG tests.

Arnaud A. de Grandmaison a7c90d8487 [PBQP] Conservativelly allocatable nodes can be spilled and give a better solution
Although such nodes are allocatable, the cost of spilling may be less than
allocating to register, so spilling the node may provide a better solution.
The assert does not account for this case, so remove it for now.

Hafiz Abid Qadeer 095b128671 Fix for http://llvm.org/bugs/show_bug.cgi?id=21744
GetVariableInfo () collected the values of the variable in a list. But it also
tried to generate the name/value pairs for children. This caused generation of
a wrong value string for may items. This function has been fixed to put value in
the list only.

The handling of --print-value related option has been moved to caller.

GetVariableInfo2 and MIResponseFormVariableInfo3 have been removed. They were
almost the duplicate of functions of similar names. I dont see any difference in
the output of -stack-list-locals and -stack-list-arguments. So these functions
just seemed unnecessary.

Char variable was being printed as a string which caused garbage output. This has
been fixed.

Some misc. cleanup.

Test cases have been added that check -stack-list-locals for struct, array and
pointers. Modified other tests which depended on hard coded line numbers.

Chandler Carruth 7ecd99163c [PM] Update the examples to reflect the removal of the
llvm/PassManager.h wrapper header and its using declarations. These now
directly use the legacy namespace.

I had updated the #include lines in my large commit but forgot that the
examples weren't being built and didn't update the code to use the
correct namespace. Sorry for the noise here.

Chandler Carruth 30d69c2e36 [PM] Remove the old 'PassManager.h' header file at the top level of
LLVM's include tree and the use of using declarations to hide the
'legacy' namespace for the old pass manager.

This undoes the primary modules-hostile change I made to keep
out-of-tree targets building. I sent an email inquiring about whether
this would be reasonable to do at this phase and people seemed fine with
it, so making it a reality. This should allow us to start bootstrapping
with modules to a certain extent along with making it easier to mix and
match headers in general.

The updates to any code for users of LLVM are very mechanical. Switch
from including "llvm/PassManager.h" to "llvm/IR/LegacyPassManager.h".
Qualify the types which now produce compile errors with "legacy::". The
most common ones are "PassManager", "PassManagerBase", and
"FunctionPassManager".

Chandler Carruth d01918fa13 [PM] Convert Polly over to directly use the legacy pass manager
namespace and header rather than the top-level header and using
declarations. These helpers impede modular builds and are going away.
Migrating away from them will also be necessary to start mixing in any
usage of the new pass manager.

Chandler Carruth 8f4f5090b4 [PM] Move away from the old llvm/PassManager.h header and its using
declarations and just use the legacy namespace qualifier in this file
and the permanent header name.

The old wrapper header is going away to make LLVM's build more modular,
and without updating Clang I can't easily start to add usage of the new
pass manager to Clang. This should make it more clear in the code which
set of types is doing what.

Chandler Carruth d066d3a7b4 Fix the last two warnings I see on Linx building 'lldb': mismatched
signed and unsigned types in comparisons.

For the text offset, use the addr_t type that is used elsewhere to get
these kinds of offsets, and which it is being compared against. This
seems to make things more consistent.

For the other, the numbers are clearly small and uninteresting, so just
cast them to the most boring 'int' type.

David Majnemer abc482effc MS ABI: Implement /volatile:ms
The /volatile:ms semantics turn volatile loads and stores into atomic
acquire and release operations.  This distinction is important because
volatile memory operations do not form a happens-before relationship
with non-atomic memory.  This means that a volatile store is not
sufficient for implementing a mutex unlock routine.

r228980: Add support for having multiple sections with the name and ...
r228889: Invert the section relocation map.
r228888: Use the existing SymbolTableIndex intsead of doing a lookup.
