| # There are 3 OS/arch pairs: |
| # - HOSTOS/HOSTARCH: pair where syz-manager will run. |
| # - TARGETOS/TARGETVMARCH: pair of the target OS under test. |
| # - TARGETOS/TARGETARCH: pair of the target test process. |
| # |
| # The last 2 differ for e.g. amd64 OS and 386 test processes (compat syscall testing). |
| # All pairs default to the current machine. All but BUILD can be overriden. |
| # |
| # For example, to test linux/amd64 on linux/amd64, you just run: |
| # make |
| # To test linux/arm64 from darwin/amd64 host, run: |
| # make HOSTOS=darwin HOSTARCH=amd64 TARGETOS=linux TARGETARCH=arm64 |
| # To test x86 compat syscalls, run: |
| # make TARGETVMARCH=amd64 TARGETARCH=386 |
| # |
| # There is one special case for extracting constants for Android |
| # (you don't need this unless you update system call descriptions): |
| # make extract TARGETOS=android SOURCEDIR=/path/to/android/checkout |
