[v5,00/11] Support disabling TCG on ARM (part 2)

Message

Philippe Mathieu-Daudé Jan. 30, 2021, 1:52 a.m. UTC

Cover from Samuel Ortiz from (part 1) [1]:

  This patchset allows for building and running ARM targets with TCG
  disabled. [...]

  The rationale behind this work comes from the NEMU project where we're
  trying to only support x86 and ARM 64-bit architectures, without
  including the TCG code base. We can only do so if we can build and run
  ARM binaries with TCG disabled.

v5:
- addressed Paolo/Richard/Thomas review comments from v4 [5].

v4 almost 2 years later... [2]:
- Rebased on Meson
- Addressed Richard review comments
- Addressed Claudio review comments

v3 almost 18 months later [3]:
- Rebased
- Addressed Thomas review comments
- Added Travis-CI job to keep building --disable-tcg on ARM

v2 [4]:
- Addressed review comments from Richard and Thomas from v1 [1]

Regards,

Phil.
