Originally committed in r339755 which was reverted in r339806 due to
an asan issue. The issue was caused by my assumption that operands to
a CallInst mapped to the FunctionType Params. CallInsts are now
handled by iterating over their ArgOperands instead of Operands.
Original Message:
Treat signed icmps as 'sinks', allowing them to be in the use-def
tree, enabling more promotions to be performed. As a sink, any
promoted incoming values need to be truncated before being used by
the signed icmp.

a shorter name ('x86-slh') for the internal flags and pass name.
Without this, you can't use the -stop-after or -stop-before
infrastructure. I seem to have just missed this when originally adding
the pass.
The shorter name solves two problems. First, the flag names were ...
really long and hard to type/manage. Second, the pass name can't be the
exact same as the flag name used to enable this, and there are already
some users of that flag name so I'm avoiding changing it unnecessarily.

Summary:
Profile count of a block is computed by multiplying its block frequency
by entry count and dividing the result by entry block frequency. Do
rounded division in the last step and update test cases appropriately.

Also added a test for the generation of these symbols in the

Summary: Extended `cxx_loop_proto` to have neste for loops. Modified `loop_proto_to_llvm` and `loop_proto_to_cxx` to handle the new protos. All protos have a set of statements designated as "inner loop" statements and a set of statements designated as "outer loop" statements.

In r339807, I broke linking the builtins libraries for simulator targets, which itself was bad, but turns out it was all completely untested and marked with FIXME in the test suite.
This fixes all the test cases so they actually work, and fixes the bug I introduced in r339807.

This reapplies an earlier version after addressing some post-commit feedback.

This patch fixes PR38125.
Instruction extension types are recorded in PromotedInsts, it can be used later in function canGetThrough. If an instruction has two users with different extension types, it will be inserted into PromotedInsts two times in function promoteOperandForOther. The second one overwrites the first one, and the final extension type is wrong, later causes problem in canGetThrough.
This patch changes the simple bool extension type to 2-bit enum type, add a BothExtension type in addition to zero/sign extension. When an user sees BothExtension for an instruction, it actually knows nothing about how that instruction is extended.

Also really test minnum/maxnum reductions.
The existing tests were only checking from
minnum/maxnum matched from a fast math compare

To lower this we now create a new V1 containing the low half of both sources and a new V2 containing the upper half of both sources. Then we created a repeated lane shuffle of those new sources to create the final result.

I noticed this during profiling of tablegen (PR28222) that we were calling Child->getType(0) which creates a ValueTypeByHwMode on the fly from the requested internal TypeSetByHwMode type and returns it by value, we then treat it as a TypeSetByHwMode reference which involves constructing a new TypeSetByHwMode on the stack with a large amount of std::map iterating/copying all along the way.
I am not an expert on tablegen, but AFAICT this is all unnecessary and we should be calling Child->getExtType(0) which returns the original TypeSetByHwMode by reference.
This gives me a 90sec reduction in msvc debug builds of x86 -gen-dag-isel.

MCJIT::getSymbolAddress was handling a non-fatal error condition of JITSymbol
as fatal. JITSymbol::operator bool returns false if no address is available
but no error is set. This can occur e.g. if the symbol name was not found.

Summary:
In r335809, Petr Hosek lays out support for what he calls the multiarch
runtimes layout. This new way of laying out the directories for runtime
libraries is workable for all platforms. Petr did some of the common
infrastructure and made it work for Linux and Fuscia. This patch is a
cleanup to the Darwin and MachO drivers to serve as a step toward
supporting it in Darwin.
This patch does primarily two things:
(1) Changes the APIs for how the Darwin driver refers to compiler-rt
libraries to use the component names, similar to how Linux and Fuscia do
(2) Removes some legacy functionality for supporting macOS versions
before 10.6. This functionality is effectively dead code because in
r339277, the support was removed from compiler-rt for generating the 10.4
runtime support library, and Xcode 10 (currently in beta) removes
libgcc_s.10.4 and libgcc_s.10.5 from the macOS SDK.
With this patch landed a subsequent patch can modify
MachO::AddLinkRuntimeLib to support the multiarch runtimes layout.
Worth noting: None of the removed functionality was actually covered in
the test suite. So no test case updates are required.
