History

[RISCV] Combine (mul (zext, zext)) -> (zext (mul (zext, zext))) (#86465 )

Building on #86248, we can also narrow the width of a mul of zexts.

This is specifically legal because on RVV we always extend to the next
power of 2 width, and multiplying two N bit integers produces a maximum
value of 2\*N bits.
So as long as we keep an inner zext of 2\*N, we will have enough space
for the multiply and won't overflow.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
