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. v3 almost 18 months later: - Rebased - Addressed Thomas review comments - Added Travis-CI job to keep building --disable-tcg on ARM v2 [2]: - Addressed review comments from Richard and Thomas from v1 [3] Regards, Phil.
