The full codegen is committed for larger multiply, so that won't make the test suite more fragile. However, it'll allow to expose the effects fo various DAG combine.

It looks like I forgot to remove a FIXME comment with the associated statement. The test does not need it and it gives the wrong impression of being an incomplete test.

Now for real. The use case supported previously is used by approximately nobody.
What's needed is support for matching argument comments in EXPECT_xxx calls to
the names of parameters of the mocked methods.

Currently we only combine shuffle nodes if they have a single user to prevent us from causing code bloat by splitting the shuffles into several different combines.
We don't take into account that in some cases we will already have combined all the users during recursively calling up the shuffle tree.
This patch keeps a list of all the shuffle nodes that have been combined so far and permits combining of further shuffle nodes if all its users are in that list.

Previously only the superscalar scheduled expansion of the dla macro for
MIPS64 was implemented. If assembler temporary register is not available
and the optional source register is not the destination register, synthesize
the address using the naive solution of adds and shifts.
This partially resolves PR/30383.
Thanks to Sean Bruno for reporting the issue!

for a quite big function with source like
%add = add nsw i32 %mul, %conv
%mul1 = mul nsw i32 %add, %conv
%add2 = add nsw i32 %mul1, %add
%mul3 = mul nsw i32 %add2, %add
; repeat couple of thousands times
that can be produced by loop unroll, getAddExpr() tries to recursively construct SCEV and runs almost infinite time.
Added recursion depth restriction (with new parameter to set it)

Fix for the formatting options combination of
BreakBeforeBinaryOperators: All, AlignAfterOpenBracket: AlwaysBreak not
handling long templates correctly. This patch allows a break after an
opening left parenthesis, TemplateOpener, or bracket when both options
are enabled.
Patch by Daphne Pfister, thank you!
Fixes llvm.org/PR30304.

Summary:
This tells clang about all of the different AVR microcontrollers.
It also adds code to define the correct preprocessor macros for each
device.

Summary:
Previously the method would simply return false, causing every single
inline assembly constraint to trigger a compile error.
This adds inline assembly constraint support for the AVR target.
This patch is derived from the code in
AVRISelLowering::getConstraintType.

This also removes the use of instcombine as we can max the patterns
produced by argument promotion directly with the more powerful tools in

Summary:
This patch implements addsf3/__aeabi_fadd in asm for Thumb1.
Compared with generic C version (lib/fp_add_impl.inc), it
1. all constants are materialized instead of loading from constant pool
2. no stack spills (C version uses 136 bytes stack space)
3. clz() is called only when necessary. (C version always calls it)

When compiled with Clang for Windows, this was emitting "enumerator value
evaluates to 4294967295, which cannot be narrowed to type 'int' [-Wc++11-narrowing]".
The test should more strenuously avoid poking this ABI deficiency (and it
already has coverage for explicitly specified underlying types).

libcxx's tests use various C Standard Library functions that have been
marked by MSVC's CRT as deprecated by Microsoft (not by ISO).
libcxx's usage is cromulent (just checking with decltype to see if the functions
are being dragged in by various headers as required by the Standard), so
defining _CRT_SECURE_NO_WARNINGS will silence the warnings in a targeted manner.
This needs to be defined before including any CRT headers.
Also, make this file prettier.
