This amends Idad7ef138cdbcbd209d390bf6c10ca8365d4619f. With the change,
when there is a member that returns IsHostOsDependent() == true,
the sdk having the member and the member itself are disable for host and
only the os that the member supports is explicitly enabled.
However, that change will cause a problem when we add the support for
the linux_bionic_arm64 target. The target is not enabled when building
sdk snapshots. The only linux_bionic target that is enabled is
'linux_bionic_x86_64'. However, since the granularity is os which is
linux_bionic, the snapshot is generated as follows.
cc_prebuilt_binary {
target: {
host: {
enabled: false,
},
linux_bionic: {
enabled: true,
},
linux_bionic_x86_64: {
srcs: ["x86_64/bin/..."],
},
// no srcs for linux_bionic_arm64
},
}
Above is a problem for linux_bionic_arm64 target because the target is
enabled (via linux_bionic.enabled: true), but srcs is not provided.
To fix the problem, the enabling of a target is done in a target
(os_arch) granularity, rather than os granularity. For example, above
now becomes ...
cc_prebuilt_binary {
target: {
host: {
enabled: false,
},
linux_bionic_x86_64: {
enabled: true,
srcs: ["x86_64/bin/..."],
},
},
}
Only the targets that the snapshot actually can provide srcs are enabled
and the rest of the host targets are disabled.
