Nico Weber [Wed, 6 Apr 2022 13:30:39 +0000 (09:30 -0400)]
[dsymutil] Fix O(n^2) behavior when running on ld64.lld's current ICF output

STABS information consists of a list of records in the linked binary
that look like this:

  OSO: path/to/some.o
  SO: path/to/some.c
  FUN: sym1
  FUN: sym2
  ...

The linked binary has one such set of records for every .o file linked
into it.

When dsymutil processes the binary's STABS information, it:

1. Reads the .o file mentioned in the OSO line
2. For each FUN entry after it in the main executable's STABS info:
  a) it looks up that symbol in the symbol of that .o file
  b) if it doesn't find it there, it goes through all symbols in the
     main binary at the same address and sees if any of those match

With ICF, ld64.lld's STABS output claims that all identical functions
that were folded are in the .o file of the one that's deemed the
canonical one. Many small functions might be folded into a single
function, so there are .o OSO entries that end up with many FUN lines,
but almost none of them exist in the .o file's symbol table.

Previously, dsymutil would do a full scan of all symbols in the main
executable _for every of these entries_.

This patch instead scans all aliases once and remembers them per name.
This reduces the alias resolution complexity from
O(number_of_aliases_in_o_file * number_of_symbols_in_main_executable) to
O(number_of_aliases_in_o_file * log(number_of_aliases_in_o_file)).

In practice, it reduces the time spent to run dsymutil on
Chromium Framework from 26 min (after https://reviews.llvm.org/D89444)
or 12 min (before https://reviews.llvm.org/D89444) to ~8m30s.

We probably want to change how ld64.lld writes STABS entries when ICF
is enabled, but making dsymutil not have pathological performance for
this input seems like a good change as well.

No expected behavior change (other than it's faster). I verified that
for Chromium Framework, the generated .dSYM is identical with and
without this patch.

This patch adds the minimum required to successfully lower vp.icmp via

Regular ISD::SETCC goes through a lot of canonicalization which targets

supports expansion of individual condition codes and a non-boolean
return type. Support for all of that will follow in later patches.

In the case of RVV this largely isn't a problem as the vector integer
comparison instructions are plentiful enough that it can lower all
VP_SETCC nodes on legal integer vectors except for boolean vectors,
which regular SETCC folds away immediately into logical operations.

Floating-point VP_SETCC operations aren't as well supported in RVV and
the backend relies on condition code expansion, so support for those
operations will come in later patches.

Jean Perier [Wed, 6 Apr 2022 13:37:48 +0000 (15:37 +0200)]
[flang] Add runtime API to catch unit number out of range

Unit numbers must fit on a default integer. It is however possible that
the user provides the unit number in UNIT with a wider integer type.
In such case, lowering was previously silently narrowing
the value and passing the result to the BeginXXX runtime entry points.
Cases where the conversion caused overflow were not reported/caught.
Most existing compilers catch these errors and raise an IO error.
Add a CheckUnitNumberInRange runtime API to do the same in f18.

This runtime API has its own error management interface (i.e., does not
use GetIoMsg, EndIo, and EnableHandlers) because the usual error
management requires BeginXXX to be called to set up the error
management. But in this case, the BeginXXX cannot be called since
the bad unit number that would be provided to it overflew (and in the worst
case scenario, the narrowed value could point to a different valid unit
already in use). Hence I decided to make an API that must be called
before the BeginXXX and should trigger the whole BeginXXX/.../EndIoStatement
to be skipped in case the unit number is too big and the user enabled
error recovery.

Note that CheckUnitNumberInRange accepts negative numbers (as long as
they can fit on a default integer), because unit numbers may be negative
if they were created by NEWUNIT.

[Support/Hash functions] Change the `final()` and `result()` of the hashing functions to return an array of bytes

Returning `std::array<uint8_t, N>` is better ergonomics for the hashing functions usage, instead of a `StringRef`:

* When returning `StringRef`, client code is "jumping through hoops" to do string manipulations instead of dealing with fixed array of bytes directly, which is more natural
* Returning `std::array<uint8_t, N>` avoids the need for the hasher classes to keep a field just for the purpose of wrapping it and returning it as a `StringRef`

As part of this patch also:

* Introduce `TruncatedBLAKE3` which is useful for using BLAKE3 as the hasher type for `HashBuilder` with non-default hash sizes.
* Make `MD5Result` inherit from `std::array<uint8_t, 16>` which improves & simplifies its API.

[Attributor] Introduce AAInstanceInfo

The Attributor, as many other parts in LLVM, uses pointer equivalence
for `llvm::Value`s. This only works as long as `llvm::Value`s are
dynamically unique, or, to be exact, we will never end up with the same
`llvm::Value` representing two dynamic instances. We already provided a
helper to check the former, namely `AA::isDynamicallyUnique`, however we
could not check the latter. In this patch we move the logic into a
separate AA which helps with the growing complexity and use cases. We
also extend the interface to answer the second question rather than the
first. So we do not determine dynamically uniqueness but if we might end
up with the `llvm::Value` describing a different dynamic instance. Note
that the latter is very much tied to the Attributor capabilities to look
through memory, recursion, etc. so we need to update the logic as we go.
