[CXX TLS calling convention] Add CXX TLS calling convention.

This commit adds a new target-independent calling convention for C++ TLS
access functions. It aims to minimize overhead in the caller by perserving as
many registers as possible.

The target-specific implementation for X86-64 is defined as following:
  Arguments are passed as for the default C calling convention
  The same applies for the return value(s)
  The callee preserves all GPRs - except RAX and RDI

The access function makes C-style TLS function calls in the entry and exit
block, C-style TLS functions save a lot more registers than normal calls.
The added calling convention ties into the existing implementation of the
C-style TLS functions, so we can't simply use existing calling conventions
such as preserve_mostcc.

Here is a very simple example: if a vadd has the cost 1, and if we double VF
so that we need two registers to perform it, then its cost will become 4 with
the current implementation, which will prevent us to use larger VF.

[llvm-profdata] Add support for weighted merge of profile data

This change adds support for an optional weight when merging profile data with the llvm-profdata tool.
Weights are specified by adding an option ':<weight>' suffix to the input file names.

Adding support for arbitrary weighting of input profile data allows for relative importance to be placed on the
input data from multiple training runs.

Both sampled and instrumented profiles are supported.

7 years agoCodeGen peephole: fold redundant phys reg copies
JF Bastien [Thu, 3 Dec 2015 23:43:56 +0000 (23:43 +0000)]
CodeGen peephole: fold redundant phys reg copies

Code generation often exposes redundant physical register copies through
virtual registers such as:

  %vreg = COPY %PHYSREG
  %PHYSREG = COPY %vreg

There are cases where no intervening clobber of %PHYSREG occurs, and the
later copy could therefore be removed. In some cases this further allows
us to remove the initial copy.

This patch contains a motivating example which comes from the x86 build
of Chrome, specifically cc::ResourceProvider::UnlockForRead uses
libstdc++'s implementation of hash_map. That example has two tests live
at the same time, and after machine sinking LLVM has confused itself
enough and things spilling EFLAGS is a great idea even though it's
never restored and the comparison results are both live.

Before this patch we have:
  DEC32m %RIP, 1, %noreg, <ga:@L>, %noreg, %EFLAGS<imp-def>
  %vreg1<def> = COPY %EFLAGS; GR64:%vreg1
  %EFLAGS<def> = COPY %vreg1; GR64:%vreg1
  JNE_1 <BB#1>, %EFLAGS<imp-use>

Both copies are useless. This patch tries to eliminate the later copy in
a generic manner.

dec is especially confusing to LLVM when compared with sub.

I wrote this patch to treat all physical registers generically, but only
remove redundant copies of non-allocatable physical registers because
the allocatable ones caused issues (e.g. when calling conventions weren't
properly modeled) and should be handled later by the register allocator

The following tests used to failed when the patch also replaced allocatable
This happens because COPY has other special meaning for e.g. dependency
breakage and x87 FP stack.

Note that all other backends' tests pass.

* Add ExpandConstant to handle i128 constants, ExpandNode
  to handle ISD::Constant node.
* Add one more parameter to getCommonSubClass and firstCommonClass,
  to guarantee that returned common sub class will contain the specified
  simple value type.
  This extra parameter is used by EmitCopyFromReg in InstrEmitter.cpp.
* Fix infinite loop in getTypeLegalizationCost when f128 is the value type.
* Fix printOperand to handle null operand.
* Enhance ISD::BITCAST node to handle f128 constant.

[X86] MS inline asm: produce error when encountering "<type> ptr <reg name>"

Currently "<type> ptr <reg name>" treated as <reg name> in MS inline asm, ignoring the "<type> ptr" completely and possibly ignoring the intention of the user.
Fixed llvm to produce an error when encountering "<type> ptr <reg name>" operands.

For example: andpd xmm1,xmmword ptr xmm1 --> andpd xmm1, xmm1

Remove "ExportingModule" from ThinLTO Index (NFC)

There is no real reason the index has to have the concept of an
exporting Module. We should be able to have one single unique
instance of the Index, and it should be read-only after creation
for the whole ThinLTO processing.
The linker plugin should be able to process multiple modules (in
parallel or in sequence) with the same index.

The only reason the ExportingModule was present seems to be to
implement hasExportedFunctions() that is used by the Module linker
to decide what to do with the current Module.
For now I replaced it with a query to the map of Modules path to
see if this module was declared in the Index and consider that if
it is the case then it is probably exporting function.
On the long term the Linker interface needs to evolve and this
call should not be needed anymore.
