[LICM] Remove MaybePromotable set (PR50367)

The MaybePromotable set keeps track of loads/stores for which
promotion was not attempted yet. Normally, any load/stores that
are promoted in the current iteration will be removed from this
set, because they naturally MustAlias with the promoted value.
However, if the source program has UB with metadata claiming that
a store is NoAlias, while it is actually MustAlias, and multiple
different pointers are promoted in the same iteration, it can
happen that a store is removed that is still in the MaybePromotable
set, causing a use-after-free.

While this could be fixed by explicitly invalidating values in
MaybePromotable in the LoopPromoter, I'm going with the more
radical option of dropping the set entirely here and check all
load/stores on each promotion iteration. As promotion, and especially
repeated promotion, are quite rare, this doesn't seem to have any

more precise (e.g. the example in test-legalize-type-conversion.mlir).

The bulk of this change is plumbing location tracking through the parser
and printer to make sure it can round trip (in -mlir-print-debuginfo
mode).  This is complete for generic operations, but requires manual

Recommit X86: support Swift Async context

This adds support to the X86 backend for the newly committed swiftasync
function parameter. If such a (pointer) parameter is present it gets stored
into an augmented frame record (populated in IR, but generally containing
enhanced backtrace for coroutines using lots of tail calls back and forth).

The context frame is identical to AArch64 (primarily so that unwinders etc
don't get extra complexity). Specfically, the new frame record is [AsyncCtx,
%rbp, ReturnAddr], and its presence is signalled by bit 60 of the stored %rbp
being set to 1. %rbp still points to the frame pointer in memory for backwards
compatibility (only partial on x86, but OTOH the weird AsyncCtx before the rest
of the record is because of x86).

adjacent to a prologue.

[DebugInfo][test] Check specific func name to ignore codegen differences

We use `CHECK-LABEL: define` to divide input stream into functions,
this works well on most platforms.

But there are cases that some platforms (eg: AIX) may have different
codegen , especially for global constructor and descructors.

On AIX, the codegen will have two more functions: __dtor_b,
__finalize_b, which will fail the test.

The fix is to use specific function name so that we can safely ignore
those unrelated codegen differences.

3 years ago[ADT] Remove StringRef::withNullAsEmpty
Raphael Isemann [Tue, 18 May 2021 08:30:54 +0000 (10:30 +0200)]
[ADT] Remove StringRef::withNullAsEmpty

A long time ago LLDB wanted to start using StringRef instead of
C-Strings/ConstString but was blocked by the StringRef(const char *) ctor
asserting that the C-string isn't a nullptr. To workaround this, D24697
introduced a special function called withNullAsEmpty and that's what LLDB (and
only LLDB) started to use to build StringRefs from C-strings.

A bit later it seems that withNullAsEmpty was declared too awkward to use and
instead the assert in the StringRef constructor got removed (see D24904). The
rest of LLDB was then converted to StringRef by just calling the now perfectly
usable implicit constructor.

However, it seems that the original approach with withNullAsEmpty was never
touched again since then and now just exists as a function in StringRef that
is only used in a few places in LLDB.

I removed the few uses of withNullAsEmpty in D102597 and this patch removes
the function itself. Calling the implicit StringRef(const char *) constructor
is the preferred way of doing this today.
