Subject: [PATCH 3/3] runsv: Use 64 prefix syscall if we have to
|
||
|
|
|
||
|
|
Some 32-bit architectures no longer have the 32-bit time_t syscalls.
|
||
|
|
Instead they have suffixed syscalls that returns a 64-bit time_t. If
|
||
|
|
the architecture doesn't have the non-suffixed syscall and is using a
|
||
|
|
64-bit time_t let's use the suffixed syscall instead.
|
||
|
|
|
||
|
|
This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel
|
||
|
|
headers.
|
||
|
|
|
||
|
|
If an architecture only supports the suffixed syscalls, but is still
|
||
|
|
using a 32-bit time_t report a compilation error. This avoids us have to
|
||
|
|
deal with converting between 64-bit and 32-bit values. There are
|
||
|
|
currently no architectures where this is the case.
