[PATCH RESEND v3 0/5] perf tools: Modify mksyscalltbl

[Tiezhu Yang]

I'm sorry, somehow the patchset didn't reach mailing lists.
Resending with a fewer people in the cc list, which probably
was the reason.

Thanks Alexander, Leo and Ian for your reviews and suggestions.

v3:
  -- Add a new patch to declare syscalltbl_*[] as const for all archs,
     suggested by Ian.
  -- Add a new patch to use max_nr to define SYSCALLTBL_ARM64_MAX_ID.

v2:
  -- Add a new patch to rename create_table_from_c()
     to create_sc_table(), suggested by Leo.
  -- Simplify the shell script, suggested by Alexander.

[PATCH RESEND v3 1/5] perf tools: Declare syscalltbl_*[] as const for all archs

[Tiezhu Yang]

syscalltbl_*[] should never be changing, let us declare it as const.

[PATCH RESEND v3 2/5] perf arm64: Rename create_table_from_c() to create_sc_table()

[Tiezhu Yang]

After commit 9854e7ad35fe ("perf arm64: Simplify mksyscalltbl"),
it has been removed the temporary C program and used shell to
generate syscall table, so let us rename create_table_from_c()
to create_sc_table() to avoid confusion.

[PATCH RESEND v3 3/5] perf arm64: Handle __NR3264_ prefixed syscall number

[Tiezhu Yang]

After commit 9854e7ad35fe ("perf arm64: Simplify mksyscalltbl"),
in the generated syscall table file syscalls.c, there exist some
__NR3264_ prefixed syscall numbers such as [__NR3264_ftruncate],
it looks like not so good, just do some small filter operations
to handle __NR3264_ prefixed syscall number as a digital number.

Without this patch:

  [__NR3264_ftruncate] = "ftruncate",

With this patch:

  [46] = "ftruncate",

Like x86, powerpc, mips and s390, use max_nr which is a digital
number to define SYSCALLTBL_ARM64_MAX_ID.

[PATCH RESEND v3 5/5] perf LoongArch: Simplify mksyscalltbl

[Tiezhu Yang]

In order to print the numerical entries of the syscall table,
there is no need to call the host compiler to build and then
run a program, this can be done directly by the shell script.

This is similar with commit 9854e7ad35fe ("perf arm64: Simplify
mksyscalltbl"). For now, the mksyscalltbl file of LoongArch is
almost same with arm64.
