This commit helps with platform code separation (fixes#3). It should also help with the build as we can simply include all `impl_*.c` files regardless of OS / arch.
Note: this patch contains breaking changes in `include/cpu_features_macros.h`
- `CPU_FEATURES_OS_LINUX_OR_ANDROID` does not exist anymore
- `CPU_FEATURES_OS_FREEBSD`, `CPU_FEATURES_OS_ANDROID` and `CPU_FEATURES_OS_LINUX` are now mutually exclusive (i.e. `CPU_FEATURES_OS_ANDROID` does not imply `CPU_FEATURES_OS_LINUX`)
- `CPU_FEATURES_OS_DARWIN` has been renamed into `CPU_FEATURES_OS_MACOS` to be able to target non-Mac Apple products (IOS, TV, WATCH). They are now targetable with `CPU_FEATURES_OS_IPHONE`. This matches Apple naming convention described in [this stackoverflow](https://stackoverflow.com/a/49560690).
- Use stderr for issues
- Add usage to run_integration.sh (-h or --help)
- deduce toolchain and qemu config from TARGET
- Bump QEMU from 2.11.1 to 5.2.0
- fix qemu build on Archlinux
- Bump Linaro:
toolchain 7.2-2017.11 -> 7.5-2019.12
sysroot 2.25-2017.11 -> 2.25-2019.12
- Bump codescape from 2017.10-08 to 2020.06-01
- migrate from mips-r2-hard to mips-r6-hard
The build fails with following message when -Werror
and -Werror=return-type are enabled.
In function ‘GetCacheTypeString’:
error: control reaches end of non-void function [-Werror=return-type]
Simple fix is to return explicitly communicate to
the compiler that certain block is not reachable.
This is a non functional change, it allows:
- Getting rid of `unix_features_aggregator`
- Have a single blob describing the features
- Fix wrong mocking of `hwcaps`
Downside: abuse of macros makes the code slightly magical and harder to understand.
It think it's still an improvement over the current situation as there's less repetition and less chances to get something wrong.
