common header is created which holds the test related language specific
types and functions.

In addPhysRegDeps, subregister entries of the defined register were previously
not removed from Uses or Defs, which resulted in extra redundant edges for
subregs around the register definition.
This is principally NFC (in very rare cases some node got a different height).
This makes the DAG more readable and efficient in some cases.

To do this:
1. Add fixup_riscv_relax fixup types which eventually will
transfer to R_RISCV_RELAX relocation types.
2. Insert R_RISCV_RELAX relocation types to auipc function call

Summary:
If NaryReassociate succeed it will, when replacing the old instruction
with the new instruction, also recursively delete trivially
dead instructions from the old instruction. However, if the input to the
NaryReassociate pass contain dead code it is not save to recursively
delete trivially deadinstructions as it might lead to deleting the newly
created instruction.
This patch will fix the problem by using WeakVH to detect this
rare case, when the newly created instruction is dead, and it will then
restart the basic block iteration from the beginning.

This reverts r333147 until https://reviews.llvm.org/D47308 is ready to
be reviewed. r333147 exposed a behavioural difference between
OrcCBindingsStack::findSymbolIn() and OrcCBindingsStack::findSymbol(),
where only the latter does name mangling. After r333147 that causes a
test failure on OSX, because the new test looks for main using
findSymbolIn() but the mangled name is _main.

The match pattern in the definition of LXSDX is xoaddr, so the Pseudo
instruction XFLOADf64 never gets selected. XFLOADf64 expands to LXSDX/LFDX post
RA based on the register pressure. To avoid ambiguity, we need to remove the
select pattern for LXSDX, same as what was done for LXSD. STXSDX also have
the same issue.

Summary:
Remove the call to DiagnoseUseOfDecl in LookupMemberExpr because:
1. LookupMemberExpr eagerly lookup both getter and setter, reguardless
if they are used or not. It causes wrong diagnostics if you are only
using getter.
2. LookupMemberExpr only diagnoses getter, but not setter.
3. ObjCPropertyOpBuilder already DiagnoseUseOfDecl when building getter
and setter. Doing it again in LookupMemberExpr causes duplicated
diagnostics.

In many cases JIT users will know in which module a symbol
resides. Avoiding to search other modules can be more efficient. It

This patch continues a series of patches started by r332907 (reapplied
as r332917).
In this commit we introduce new matching opcode for the MatchTable:
GIM_SwitchType, similar to GIM_SwitchOpcode, and use it to switch over
LLTs of def operands of root instructions on the 2nd level of the
MatchTable within GIM_SwitchOpcode's cases.
This is expected to decrease time GlobalISel spends in its
InstructionSelect pass by about 6.5% for an -O0 build as measured on

In this commit we move register bank checks back from epilogue of

The only reason this was here was so that Module could have a
function called CreateJITModule which created things in a special
order. Instead of making this specific to creating JIT modules,
I converted this into a template function that can create a module
for any type of object file plugin and just forwards arguments
through. Since the template is not instantiated in Core, the linker
(and header file) dependency moves to the point where it is
instantiated, which only happens in Expression. Conceptually, this
location also makes more sense for a dependency on ObjectFileJIT.
After all, we JIT expressions so it's no surprise that Expression
needs to make use of ObjectFileJIT.

This patch continues a series of patches started by r332907 (reapplied
as r332917).
In this commit we greedily stuff 2nd level GroupMatcher's common
conditions with as many predicates as possible. This is purely
post-processing and it doesn't change which rules are put into the
groups in the first place: that decision is made by looking at the
first common predicate only.
The compile time improvements are minor and well within error margin,
however, it's highly improbable that this transformation could
pessimize performance, thus I'm still committing it for potential
gains for targets not implementing GlobalISel yet and out of tree
targets.

Sort pseudo instructions first while emitting enum's for target
instructions info. That puts them close to each other and to generic
G_* opcodes for GlobalISel. This makes it easier to build small jump
tables over opcodes that could be directly embedded into MatchTable's
Tablegen'erated for GlobalISel's InstructionSelect.

Summary:
Set CostPerUse higher for registers that are not used in the compressed
instruction set. This will influence the greedy register allocator to reduce
the use of registers that can't be encoded in 16 bit instructions. This
affects register allocation even when compressed instruction isn't targeted,
we see no major negative codegen impact.

unusual types.
Following the observed behavior of GCC, we now return -1 for vector types
(along with all of our extensions that GCC doesn't support), and for atomic
types we classify the underlying type.
GCC appears to have changed its classification for function and array arguments
between version 5 and version 6. Previously it would classify them as pointers
in C and as functions or arrays in C++, but from version 6 onwards, it
classifies them as pointers. We now follow the more recent GCC behavior rather
than emulating what I can only assume to be a historical bug in their C++
support for this builtin.
Finally, no version of GCC that I can find has ever used the "method"
classification for C++ pointers to member functions. Instead, GCC classifies
them as record types, presumably reflecting an internal implementation detail,
but whatever the reason we now produce compatible results.
