Add IR fixups for RenderScript ABI mismatch between ARMV7 frontend and x86 backend
Expression evaluation for function calls to certain public RenderScript
API functions in libRSCPURef can segfault.
`slang`,
the compiler frontend for RenderScript embeds an ARM specific triple in
IR that is shipped in the app, after generating IR that has some
assumptions that an ARM device is the target.
As the IR is then compiled on a device of unknown (at time the IR was
generated at least) architecture, when calling RenderScript API function
as part of debugger expressions, we have to perform a fixup pass that
removes those assumptions right before the module is sent to be
generated by the llvm backend.
This issue is caused by multiple problems with the ARMv7-specific
assumptions encoded in the LLVM IR. x86 large value returns use a hidden
first argument (mapping to llvm::Attribute::StructRet), which can't be
picked up by the JIT due to the mismatch between IR generated by the
slang frontend and llvm backend. This means that code generated by bcc
did not necessarily match the default SysV Linux/Android ABI used by the
LLDB JIT

Reapply r276856 "Adjust Registry interface to not require plugins to export a registry"
This version has two fixes compared to the original:
* In Registry.h the template static members are instantiated before they are
used, as clang gives an error if you do it the other way around.
* The use of the Registry template in clang-tidy is updated in the same way as
has been done everywhere else.
Original commit message:
Currently the Registry class contains the vestiges of a previous attempt to
allow plugins to be used on Windows without using BUILD_SHARED_LIBS, where a
plugin would have its own copy of a registry and export it to be imported by
the tool that's loading the plugin. This only works if the plugin is entirely
self-contained with the only interface between the plugin and tool being the
registry, and in particular this conflicts with how IR pass plugins work.
This patch changes things so that instead the add_node function of the registry
is exported by the tool and then imported by the plugin, which solves this
problem and also means that instead of every plugin having to export every
registry they use instead LLVM only has to export the add_node functions. This
allows plugins that use a registry to work on Windows if
LLVM_EXPORT_SYMBOLS_FOR_PLUGINS is used.

AMDGPU: add execfix flag to SI_ELSE
Summary:
SI_ELSE is lowered into two parts:
s_or_saveexec_b64 dst, src (at the start of the basic block)
s_xor_b64 exec, exec, dst (at the end of the basic block)
The idea is that dst contains the exec mask of the preceding IF block. It can
happen that SIWholeQuadMode decides to switch from WQM to Exact mode inside
the basic block that contains SI_ELSE, in which case it introduces an instruction
s_and_b64 exec, exec, s[...]
which masks out bits that can correspond to both the IF and the ELSE paths.
So the resulting sequence must be:
s_or_savexec_b64 dst, src
s_and_b64 exec, exec, s[...] <-- added by SIWholeQuadMode
s_and_b64 dst, dst, exec <-- added by SILowerControlFlow
s_xor_b64 exec, exec, dst
Whether to add the additional s_and_b64 dst, dst, exec is currently determined
via the ExecModified tracking. With this change, it is instead determined by
an additional flag on SI_ELSE which is set by SIWholeQuadMode.
Finally: It also occured to me that an alternative approach for the long run
is for SILowerControlFlow to unconditionally emit
s_or_saveexec_b64 dst, src
...
s_and_b64 dst, dst, exec
s_xor_b64 exec, exec, dst
and have a pass that detects and cleans up the "redundant AND with exec"
pattern where possible. This could be useful anyway, because we also add
instructions
s_and_b64 vcc, exec, vcc
before s_cbranch_scc (in moveToALU), and those are often redundant. I have
some pending changes to how KILL is lowered that could also benefit from
such a cleanup pass.
In any case, this current patch could help in the short term with the whole
ExecModified business.

Don't invoke getName() from Function::isIntrinsic().
Summary:
getName() involves a hashtable lookup, so is expensive given how
frequently isIntrinsic() is called. (In particular, many users cast to
IntrinsicInstr or one of its subclasses before calling
getIntrinsicID().)
This has an incidental functional change: Before, isIntrinsic() would
return true for any function whose name started with "llvm.", even if it
wasn't properly an intrinsic. The new behavior seems more correct to
me, because it's strange to say that isIntrinsic() is true, but
getIntrinsicId() returns "not an intrinsic".
Some callers want the old behavior -- they want to know whether the
caller is a recognized intrinsic, or might be one in some other version
of LLVM. For them, we added Function::hasLLVMReservedName(), which
checks whether the name starts with "llvm.".
This change is good for a 1.5% e2e speedup compiling a large Eigen
benchmark.

[CUDA] Align kernel launch args correctly when the LLVM type's alignment is different from the clang type's alignment.
Summary:
Before this patch, we computed the offsets in memory of args passed to
GPU kernel functions by throwing all of the args into an LLVM struct.
clang emits packed llvm structs basically whenever it feels like it, and
packed structs have alignment 1. So we cannot rely on the llvm type's
alignment matching the C++ type's alignment.
This patch fixes our codegen so we always respect the clang types'
alignments.

Adjust coercion of aggregates on RenderScript
Summary:
In RenderScript, the size of the argument or return value emitted in the
IR is expected to be the same as the size of corresponding qualified
type. For ARM and AArch64, the coercion performed by Clang can
change the parameter or return value to a type whose size is different
(usually larger) than the original aggregate type. Specifically, this
can happen in the following cases:
- Aggregate parameters of size <= 64 bytes and return values smaller
than 4 bytes on ARM
- Aggregate parameters and return values smaller than bytes on
AArch64
This patch coerces the cases above to an integer array that is the same
size and alignment as the original aggregate. A new field is added to
TargetInfo to detect a RenderScript target and limit this coercion just
to that case.

Summary:
This patch is re-introducing the code to fix the
dynamic hooking on windows and to fix a compiler
warning on Apple.

* https://reviews.llvm.org/D22610
* https://reviews.llvm.org/rL276311
* https://reviews.llvm.org/rL276490
Both architecture are using different techniques to
hook on library functions (memchr, strcpy,...).
On Apple, the function is not dynamically hooked and
the symbol always points to a valid function
(i.e. can't be null). The REAL macro returns the
symbol.
On windows, the function is dynamically patch and the
REAL(...) function may or may not be null. It depend
on whether or not the function was hooked correctly.
Also, on windows memcpy and memmove are the same.
```
#if !defined(__APPLE__)

# define REAL(x) __interception::PTR_TO_REAL(x)
# define ASSIGN_REAL(dst, src) REAL(dst) = REAL(src)

Make bugpoint transform conditional jumps into unconditional jumps.
Summary:
Add a pass to bugpoint to make it transform conditional jumps into unconditional jumps.
Often, bugpoint generates output that has large numbers of br undef jumps, where
one side is dead.
What is happening is two fold:
1. It never tries to just pick a direction for the jump, and just see what happens
<<<< this patch
2. SimplifyCFG no longer is a good match for bugpoint's usecase. It
does too much.
Even things in SimplifyCFG, like removeUnreachableBlocks, go to great
lengths to transform undefined behavior into blocks and kill large
parts of the CFG. This is great for regular code, not so much for
bugpoint, which often generates UB on purpose (store undef is a great
example).
<<<< a followup patch that is coming, to move simplifycfg into a
separate reduction pass, and move the existing reduceCrashingBlocks
pass to use simpleSimplifyCFG.
Both of these patches significantly reduce the size and complexity of bugpoint
generated testcases.
