Subject: [PATCH] nvptx: Provide stub 'getpid', 'kill', 'stat'
Date: Thu, 19 Jan 2023 22:53:37 +0100 [thread overview]
Message-ID: <20230119215337.2002000-1-thomas@codesourcery.com> (raw)
In-Reply-To: <ae825c453f484ffd99c9be34af726089@mentor.com>
... as implemented for GCN in 'newlib/libc/sys/amdgcn/*' files, but (for now)
still adding to the catch-all 'newlib/libc/machine/nvptx/misc.c' file.
This is necessary for the GCC/Fortran I/O system, for example.
