The variables corresponding to command line options are named mechanically.
Because the option for the variable is -noinhibit-exec and not -no-inhibit-exec,
it should be name this way.

Eventually, there will be more things that CommandAlias contains, and I don't want accessors for each of them on the CommandIntepreter
Eventually, we also won't pass around copies of CommandAlias, but that's for a later patch

We follow the comments mentioned in http://reviews.llvm.org/D16842#344378 to
implement this new patch.

This patch implements the following vsx instructions:

Vector load/store:
lxv lxvx lxvb16x lxvl lxvll lxvh8x lxvwsx
stxv stxvb16x stxvh8x stxvl stxvll stxvx
Scalar load/store:
lxsd lxssp lxsibzx lxsihzx
stxsd stxssp stxsibx stxsihx
21 instructions

Also note that the operand order changed; the default label is now listed
after the regular labels.

This re-applies r262886 with a fix for 32 bit platforms that have 8 byte
pointer alignment, effectively reverting r262892.

Original Message:

  Currently some SDNode operands are malloc'd, some are stored inline in
  subclasses of SDNode, and some are thrown into a BumpPtrAllocator.
  This scheme is complex, inconsistent, and makes refactoring SDNodes
  fairly difficult.

  Instead, we can allocate all of the operands using an ArrayRecycler
  that wraps a BumpPtrAllocator. This keeps the cache locality when
  iterating operands, improves locality when iterating SDNodes without
  looking at operands, and vastly simplifies the ownership semantics.

  It also means we stop overallocating SDNodes by 2-3x and will make it
  simpler to fix the rampant undefined behaviour we have in how we
  mutate SDNodes from one kind to another (See llvm.org/pr26808).

  This is NFC other than the changes in memory behaviour, and I ran some
  LNT tests to make sure this didn't hurt compile time. Not many tests
  changed: there were a couple of 1-2% regressions reported, but there
  were more improvements (of up to 4%) than regressions.

llvm-svn: 262902

Move ProcessAliasOptionsArgs to be a static on CommandAlias; it wasn't using any instance data on the CommandInterpreter anyway

This small step removes one piece of alias machinery from the CommandInterpreter into the CommandAlias

llvm-svn: 262901

Change the way command aliases are stored. Go from a model where a map holds the alias -> underlying command binding and another map holds the alias -> options, to a model where one single map holds the alias -> (all useful data) combination

Right now, obviously, this is just the pair of (CommandObjectSP,OptionArgVectorSP), so NFC

This is step one of a larger - and tricky - refactoring which will turn command aliases into interesting objects instead of passive storage that the command interpreter does smart things to
This refactoring, in turn, will allow us to do interesting things with aliases, such as intelligent and customizable help

Looks like the largest SDNode is different between 32 and 64 bit now,
so this is breaking 32 bit bots. Reverting while I figure out a fix.

This reverts r262886.

Before this change, we would get the type definition in the middle
of the instruction.
E.g., %0(48) = G_ADD %struct_alias = type { i32, i16 } %edi, %edi

Now, we have just the expected type name:
%0(48) = G_ADD %struct_alias %edi, %edi

llvm-svn: 262885

Without actually parsing a type it is difficult to perdict where
the type definition ends. In other words, instead of expecting
the user of the parser API to hand over only the relevant bits
of the string being parsed, take the whole string, parse the type,
and get back the number of characters that have been read.

This will be used by the MIR testing infrastructure.

exactly the same as clang's existing [[clang::fallthrough]] attribute, which
has been updated to have the same semantics. The one significant difference
is that [[fallthrough]] is ill-formed if it's not used immediately before a
switch label (even when -Wimplicit-fallthrough is disabled). To support that,
we now build a CFG of any function that uses a '[[fallthrough]];' statement
to check.

In passing, fix some bugs with our support for statement attributes -- in
particular, diagnose their use on declarations, rather than asserting.

This should make it clearer how this proposed patch:
http://reviews.llvm.org/D11393
...will change codegen.

llvm-svn: 262875

I noticed this test as part of:
http://reviews.llvm.org/D11393
...which is confusing enough as-is. 
Let's show the exact codegen, so the changes will be more obvious.

llvm-svn: 262874

Now the type API is always available, but when global-isel is not
built the implementation does nothing.

Note: The implementation free of ifdefs is WIP and tracked here in PR26576.

Implement support for [[nodiscard]] in C++1z that is based off existing support for warn_unused_result, and treat it as an extension pre-C++1z. This also means extending the existing warn_unused_result attribute so that it can be placed on an enum as well as a class.
