[PATCH v4 0/7] tcg: pc-relative translation blocks


From: Richard Henderson
Subject: [PATCH v4 0/7] tcg: pc-relative translation blocks
Date: Tue, 6 Sep 2022 10:11:19 +0100

The goal here is to reduce the amount of code generation when the
guest kernel enables address space randomization.  This requires
extensive changes to each target, so opt-in with TARGET_TB_PCREL.

This is split out of v3, which also contained target/arm changes,
as I now have patches for x86 and s390x as well.
