From 9d45efe523ffb2d2fc1350aeaba9f1cfe9f58815 Mon Sep 17 00:00:00 2001

Subject: [PATCH] aarch64: Fix SVE ACLE gimple folds for C++ LTO [PR116629]
To: gcc-patches@gcc.gnu.org
From: Richard Sandiford <richard.sandiford@arm.com>
The SVE ACLE code has two ways of handling overloaded functions.
One, used by C, is to define a single dummy function for each unique
overloaded name, with resolve_overloaded_builtin then resolving calls
to real non-overloaded functions. The other, used by C++, is to
define a separate function for each individual overload.
The builtins harness assigns integer function codes programmatically.
However, LTO requires it to use the same assignment for every
translation unit, regardless of language. This means that C++ TUs
need to create (unused) slots for the C overloads and that C TUs
need to create (unused) slots for the C++ overloads.
In many ways, it doesn't matter whether the LTO frontend itself
uses the C approach or the C++ approach to defining overloaded
functions, since the LTO frontend never has to resolve source-level
overloading. However, the C++ approach of defining a separate
function for each overload means that C++ calls never need to
be redirected to a different function. Calls to an overload
can appear in the LTO dump and survive until expand. In contrast,
calls to C's dummy overload functions are resolved by the front
end and never survive to LTO (or expand).
Some optimisations work by moving between sibling functions, such as _m
to _x. If the source function is an overload, the expected destination
function is too. The LTO frontend needs to define C++ overloads if it
wants to do this optimisation properly for C++.
The PR is about a tree checking failure caused by trying to use a
stubbed-out C++ overload in LTO. Dealing with that by detecting the
stub (rather than changing which overloads are defined) would have
turned this from an ice-on-valid to a missed optimisation.
In future, it would probably make sense to redirect overloads to
non-overloaded functions during gimple folding, in case that exposes
more CSE opportunities. But it'd probably be of limited benefit, since
it should be rare for code to mix overloaded and non-overloaded uses of
the same operation. It also wouldn't be suitable for backports.
