[PATCH 0/3] Replace TARGET_TB_PCREL with CF_PCREL

Posted by Anton Johansson via 1 year, 2 months ago

This patchset entirely replaces the macro TARGET_TB_PCREL with
a field in TranslationBlock.cflags called CF_PCREL, and is a
first step towards removing target-specific assumptions from
non-target/ directories.

The grand goal is to allow for heterogeneous QEMU binaries
consisting of multiple frontends.

RFC: https://lists.nongnu.org/archive/html/qemu-devel/2022-12/msg04518.html

Anton Johansson (3):
  include/exec: Introduce `CF_PCREL`
  Replace `TARGET_TB_PCREL` with `CF_PCREL`
  target: Set `CF_PCREL` for arm and i386 frontends
