Summary: I left --build-system for backwards compat, in case there are scripts using it. Feel free to ask for its removal too.

Similar to the template cases in r262050, when a C++ method in an
unavailable struct/class calls unavailable API, don't diagnose an error.
I.e., this case was failing:
void foo() __attribute__((unavailable));
struct __attribute__((unavailable)) A {
void bar() { foo(); }
};
Since A is unavailable, A::bar is allowed to call foo. However, we were
emitting a diagnostic here. This commit checks up the context chain
from A::bar, in a manner inspired by SemaDeclAttr.cpp:isDeclUnavailable.
I expected to find other related issues but failed to trigger them:
- I wondered if DeclBase::getAvailability should check for
`TemplateDecl` instead of `FunctionTemplateDecl`, but I couldn't find
a way to trigger this. I left behind a few extra tests to make sure
we don't regress.
- I wondered if Sema::isFunctionConsideredUnavailable should be
symmetric, checking up the context chain of the callee (this commit
only checks up the context chain of the caller). However, I couldn't
think of a testcase that didn't require first referencing the
unavailable type; this, we already diagnose.

This is a follow-up to r261512, which made the 'strict' availability
attribute flag behave like 'unavailable'. However, that fix was
insufficient. The following case would (erroneously) error when the
deployment target was older than 10.9:
struct __attribute__((availability(macosx,strict,introduced=10.9))) A;
__attribute__((availability(macosx,strict,introduced=10.9))) void f(A*);
The use of A* in the argument list for f is valid here, since f and A
have the same availability.
The fix is to return AR_Unavailable from DeclBase::getAvailability
instead of AR_NotYetIntroduced. This also reverts the special handling
added in r261163, instead relying on the well-tested logic for
AR_Unavailable.

- move alias help generation to CommandAlias, out of CommandInterpreter
- make alias creation use argument strings instead of OptionArgVectorSP; the former is a more reasonable currency than the latter
- remove m_is_alias from CommandObject, it wasn't actually being used
llvm-svn: 262912
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.
llvm-svn: 262911
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

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.

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

I got an OK from Eric Christopher to commit doxygen comments without prior code review upstream.

Add the wide character strdup variants (wcsdup, _wcsdup) and the MSVC
version of alloca (_alloca) and other differently named function used
by the Malloc checker.

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.
