[analyzer][NFCI] Allow clients of NoStateChangeFuncVisitor to check entire function calls, rather than each ExplodedNode in it
D105553 added NoStateChangeFuncVisitor, an abstract class to aid in creating
notes such as "Returning without writing to 'x'", or "Returning without changing
the ownership status of allocated memory". Its clients need to define, among
other things, what a change of state is.
For code like this:
f() {
g();
}
foo() {
f();
h();
}
We'd have a path in the ExplodedGraph that looks like this:
-- <g> -->
/ \
--- <f> --------> --- <h> --->
/ \ / \
-------- <foo> ------ <foo> -->
When we're interested in whether f neglected to change some property,
NoStateChangeFuncVisitor asks these questions:
÷×~
-- <g> -->
ß / \$ @&#*
--- <f> --------> --- <h> --->
/ \ / \
-------- <foo> ------ <foo> -->
Has anything changed in between # and *?
Has anything changed in between & and *?
Has anything changed in between @ and *?
...
Has anything changed in between $ and *?
Has anything changed in between × and ~?
Has anything changed in between ÷ and ~?
...
Has anything changed in between ß and *?
...
This is a rather thorough line of questioning, which is why in D105819, I was
only interested in whether state *right before* and *right after* a function
call changed, and early returned to the CallEnter location:
if (!CurrN->getLocationAs<CallEnter>())
return;
Except that I made a typo, and forgot to negate the condition. So, in this
patch, I'm fixing that, and under the same hood allow all clients to decide to
do this whole-function check instead of the thorough one.

0x00 1110 0000 0010 0010 11xx xxxx xxxx # SMOV W|Xd,Vn.H[0]

0100 1110 0000 1000 0011 11xx xxxx xxxx # UMOV Xd,Vn.D[0]
Only the zero index variants are legal, all others indexes are illegal.
To support this, new instructions are defined specifically for zero
index which is hardcoded, along an implicit 'VectorIndex0' operand.
Since the index operand is implicit and takes no bits in the encoding,
custom decoding is required to add the operand.
I'm not sure if this is the best approach but the predicate constraint
on a subset of an operand is unusual. Would be interested to hear some
alternatives.
The instructions are predicated on 'HasNEONorStreamingSVE', i.e. they're
enabled by either +neon or +streaming-sve. This follows on from the work
in D106272 to support the subset of SVE(2) instructions that are legal
in streaming mode.
Depends on D107902.

And the coroutine support in clang seems to be relatively stable. So I

This patch would make clang lookup coroutine_traits in std namespace
first. For the compatibility consideration, clang would lookup in
std::experimental namespace if it can't find definitions in std

wouldn't be break after update compiler.

Fully qualify template template parameters when printing
I discovered this quirk when working on some DWARF - AST printing prints
type template parameters fully qualified, but printed template template
parameters the way they were written syntactically, or wholely
unqualified - instead, we should print them consistently with the way we
print type template parameters: fully qualified.
The one place this got weird was for partial specializations like in
ast-print-temp-class.cpp - hence the need for checking for
TemplateNameDependenceScope::DependentInstantiation template template
parameters. (not 100% sure that's the right solution to that, though -

[mlir] speed up construction of LLVM IR constants when possible
The translation to LLVM IR used to construct sequential constants by recurring
down to individual elements, creating constant values for them, and wrapping
them into aggregate constants in post-order. This is highly inefficient for
large constants with known data such as DenseElementsAttr. Use LLVM's
ConstantData for the innermost dimension instead. LLVM does seem to support
data constants for nested sequential constants so the outer dimensions are
still handled recursively. Nevertheless, this speeds up the translation of
large constants with equal dimensions by up to 30x.
Users are advised to rewrite large constants to use flat types before
translating to LLVM IR if more efficiency in translation is necessary. This is
not done automatically as the translation is not aware of the expectations of
the overall compilation flow about type changes and indexing, in particular for
global constants with external linkage.

[NFC] Remove some unclear attribute methods
To any downstream users broken by this change, please examine your uses
of these methods and see if you can use a better method. For example,
getAttribute(AttributeList::FunctionIndex) => getFnAttr(), or
addAttribute(AttributeList::FirstArgIndex + ArgNo) =>
addParamAttribute(ArgNo). 0 corresponds to ReturnIndex, ~0 corresponds
to FunctionIndex. This may make future cleanups less painful.
I've made the mistake of assuming that these indexes are for parameters
multiple times, but actually they're based off of a weird indexing
scheme AttributeList::AttrIndex where 0 is the return value and ~0 is
the function. Hopefully renaming these methods will make this clearer.
Ideally users should use more specific methods like
AttributeList::getFnAttr().
This touches all relevant methods in AttributeList, CallBase, and Function.
This hopefully will make easier a future change to cleanup AttrIndex. A
previous worry about cleaning up AttrIndex was that too many downstream
users would have to look through all uses of AttrIndex and relevant
attribute method calls to see if anything was unintentionally hardcoded
(e.g. using 0 instead of ReturnIndex). With this change hopefully
downstream users will look at existing usages of these methods and clean
them up.

[CSSPGO] Allow inlining recursive call for preinliner
When preinliner is used for CSSPGO, we try to honor global preinliner decision as much as we can except for uninlinable callees. We rely on InlineCost::Never to prevent us from illegal inlining.
However, it turns out that we use InlineCost::Never for both illeagle inlining and some of the "not-so-beneficial" inlining.
The most common one is recursive inlining, while it can bloat size a lot during CGSCC bottom-up inlining, it's less of a problem when recursive inlining is guided by profile and done in top-down manner.
Ideally it'd be better to have a clear separation between inline legality check vs cost-benefit check, but that requires a bigger change.
This change enables InlineCost computation to allow inlining recursive calls, controlled by InlineParams. In SampleLoader, we now enable recursive inlining for CSSPGO when global preinliner decision is used.
With this change, we saw a few perf improvements on SPEC2017 with CSSPGO and preinliner on: 2% for povray_r, 6% for xalancbmk_s, 3% omnetpp_s, while size is about the same (no noticeable perf change for all other benchmarks)

[SCEVExpander] Simplify pointer overflow check
This is a followup to D104662 to generate slightly nicer code for
pointer overflow checks. Bypass expandAddToGEP and instead
explicitly generate i8 GEPs. This saves some bitcasts and negates
the value in a more obvious way. In particular, this prevents SCEV
from looking through the umul.with.overflow, same as in the integer
case.
The wrapping-pointer-ni.ll test deserves a comment: Previously,
this generated a typed GEP which used the umulo argument rather
than the multiplication result. This results in more compact IR in
that case, but effectively does the multiplication twice, the
second one is just hidden in the GEP. Reusing the umulo result
seems pretty reasonable to me.

[MipsISelLowering] avoid emitting libcalls to __multi3
Similar to D108842 and D108844.
__has_builtin(builtin_mul_overflow) returns true for 32b MIPS targets,
but Clang is deferring to compiler RT when encountering long long types.
This breaks MIPS malta_defconfig builds of the Linux kernel that are
using __builtin_mul_overflow with these types for these targets.
If the semantics of __has_builtin mean "the compiler resolves these,
always" then we shouldn't conditionally emit a libcall.
This will still need to be worked around in the Linux kernel in order to
continue to support malta_defconfig builds of the Linux kernel for this
target with older releases of clang.

[InlineCost] Introduce attributes to override InlineCost for inliner testing
This patch introduces four new string attributes: function-inline-cost,
function-inline-threshold, call-inline-cost and call-threshold-bonus.
These attributes allow you to selectively override some aspects of
InlineCost analysis. That would allow us to test inliner separately from
the InlineCost analysis.
That could be useful when you're trying to write tests for inliner and
you need to test some very specific situation, like "the inline cost has
to be this high", or "the threshold has to be this low". Right now every
time someone does that, they have get creative to come up with a way to
make the InlineCost give them the number they need (like adding ~30
load/add pairs for a trivial test). This process can be somewhat tedious
which can discourage some people from writing enough tests for their
changes. Also, that results in tests that are fragile and can be easily
broken without anyone noticing it because the test writer can't
explicitly control what input the inliner will get from the inline cost
analysis.
These new attributes will alleviate those problems to an extent.
