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. Peter mentioned in v5 [6] that since 32-bit host has been removed, we have to remove v7 targets. This is not done in this series, as linking succeeds, and there is enough material to review (no need to spend time on that extra patch if the current approach is not accepted). CI: https://gitlab.com/philmd/qemu/-/pipelines/249272441 v6: - rebased on "target/arm/Kconfig" series - introduce/use tcg_builtin() for realview machines 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.
