Subject: [PATCH v2 00/27] target/s390x: pc-relative translation blocks
Date: Sun, 11 Dec 2022 09:27:35 -0600 [thread overview]
Message-ID: <20221211152802.923900-1-richard.henderson@linaro.org> (raw)
This is the S390 specific changes required to reduce the
amount of translation for address space randomization.
Begin with some generic cleanups, then prepare by using
displacements instead of addresses when possible, then
add some tcg infrastructure to avoid a code gen ugly,
then finalize the conversion.
Changes for v2:
* Incorporate feedback, including test cases.
