Subject: [PATCH v4 00/51] tcg: optimize redundant sign extensions
Date: Tue, 26 Oct 2021 16:08:52 -0700 [thread overview]
Message-ID: <20211026230943.1225890-1-richard.henderson@linaro.org> (raw)
Currently, we have support for optimizing redundant zero extensions,
which I think was done with x86 and aarch64 in mind, which zero-extend
all 32-bit operations into the 64-bit register. But targets like Alpha,
MIPS, and RISC-V do sign-extensions instead.
But before that, split the quite massive tcg_optimize function.
