Subject: [PATCH v2 1/7] perf syscalltble: Remove syscall_table.h
Date: Mon, 10 Feb 2025 08:51:02 -0800 [thread overview]
Message-ID: <20250210165108.95894-2-irogers@google.com> (raw)
In-Reply-To: <20250210165108.95894-1-irogers@google.com>
The definition of "static const char *const syscalltbl[] = {" is done
in a generated syscalls_32.h or syscalls_64.h that is architecture
dependent. In order to include the appropriate file a syscall_table.h
is found via the perf include path and it includes the syscalls_32.h
or syscalls_64.h as appropriate.
To support having multiple syscall tables, one for 32-bit and one for
64-bit, or for different architectures, an include path cannot be
used. Remove syscall_table.h because of this and inline what it does
into syscalltbl.c.
For architectures without a syscall_table.h this will cause a failure
to include either syscalls_32.h or syscalls_64.h rather than a failure
to include syscall_table.h. For architectures that only included one
or other, the behavior matches BITS_PER_LONG as previously done on
architectures supporting both syscalls_32.h and syscalls_64.h.
