These conditions are duplicated from the dumpDeclContext function called
within the if(). This is presumably an attempt to avoid calling the
function in the case it will do nothing.
That may have made sense in the past if the code was different, but it
doesn't make sense now.

As of r343360, we support fixed-enums in C. This lead to some
warnings in project headers where a fixed enum is forward declared
then later defined. In C++, this is fine, the forward declaration is
treated as a complete type even though the definition isn't present.
We use this rule in C too, but still warn about the forward
declaration anyways. This patch suppresses the warning.

GCC and Clang in MinGW mode don't support __declspec(thread), which
after expanding macros ends up as __attribute__((thread)). Use the
GCC specific attribute __thread instead (the next one in the chain
of alternatives).

This sends these intrinsics through isel in a much more normal way. This should allow addressing mode matching in isel to make better use of the displacement field.

Make sure CodeGenPrepare doesn't emit multiple inttoptr instructions of
the same integer value while sinking address computations, but rather
CSEs them on the fly: excessive inttoptr's confuse SCEV into thinking
that related pointers have nothing to do with each other.
This problem blocks LoadStoreVectorizer from vectorizing some of the
loads / stores in a downstream target.

Summary:
This patch makes some changes related to -dag-dump-verbose.
Main use case has been when debugging how SelectionDAG is
dealing with debug info (SDDbgValue nodes).
1) We now print the number of DbgValues that are mapped to each
SDNode.
2) Removed duplicated printing of DebugLoc (nowadays DebugLoc is
printed also when not using -dag-dump-verbose).
3) Renamed SDDbgValue::dump to SDDbgValue::print, and added a
new SDDbgValue::dump that will start a new line after calling
print.
4) SDDbgValue::print now prints "Order", and it also prints
some additional information when kind is CONST/FRAMEIX/VREG.
5) SelectionDAG::dump() now dumps all SDDbgValue nodes after
the list of SDNodes (both "regular" and "ByVal" SDDbgValue:s).
Invalidated nodes are not printed.
6) Prohibit inline printing of SDNode operands that has SDDbgValue
nodes associated to them.

These two options enable/disable emission of R_{MICRO}MIPS_JALR fixups along
with PIC calls. The linker may then try to turn PIC calls into direct jumps.
By default, these fixups do get emitted by the backend, use
'-mno-relax-pic-calls' to omit them.

Summary:
nullptr can implicitly convert to Twine as Twine(nullptr) in which case it
resolves to Twine(const char *). This constructor derefs the pointer and
therefore doesn't work. Add a Twine(std::nullptr_t) = delete to make it a
compile time error.
It turns out that in-tree usage of Twine(nullptr) is confined to a single
private method in IRBuilder where foldConstant(... const Twine &Name = nullptr)
and this method is only ever called with an explicit Name argument as making it
a mandatory argument doesn't cause compile-time or run-time errors.

Similar to D55073. Without this change, the DAG combiner crashes on code
with more than 64k of stores in a single basic block that form parallelizable

Summary:
This attribute will allow users to opt specific functions out of
speculative load hardening. This compliments the Clang attribute
named speculative_load_hardening. When this attribute or the attribute
speculative_load_hardening is used in combination with the flags
-mno-speculative-load-hardening or -mspeculative-load-hardening,
the function level attribute will override the default during LLVM IR
generation. For example, in the case, where the flag opposes the
function attribute, the function attribute will take precendence.
The sticky inlining behavior of the speculative_load_hardening attribute
may cause a function with the no_speculative_load_hardening attribute
to be tagged with the speculative_load_hardening tag in
subsequent compiler phases which is desired behavior since the
speculative_load_hardening LLVM attribute is designed to be maximally
conservative.
If both attributes are specified for a function, then an error will be
thrown.
