This set improves bpf object file related rules in selftests Makefile.
  - tell git to ignore the build dir "alu32".
  - extend sub-register mode compilation to all bpf object files to give
    LLVM compiler bpf back-end more exercise.
  - auto-generate bpf kernel object file list.
  - relax sub-register mode compilation criteria.

v1 -> v2:
  - rename "kern_progs" to "progs". (Alexei)
  - spin a new patch to remove build server kernel requirement for
    sub-register mode compilation (Alexei)
  - rebase on top of KaFai’s latest "test_sock_fields" patch set.

Jiong Wang (4):
  selftests: bpf: add "alu32" to .gitignore
  selftests: bpf: extend sub-register mode compilation to all bpf object
    files
  selftests: bpf: centre kernel bpf objects under new subdir "progs"
  selftests: bpf: relax sub-register mode compilation criteria

"alu32" is a build dir and contains various files for BPF sub-register
code-gen testing.

This patch tells git to ignore it.

At the moment, we only do extra sub-register mode compilation on bpf object
files used by "test_progs". These object files are really loaded and
executed.

This patch further extends sub-register mode compilation to all bpf object
files, even those without corresponding runtime tests. Because this could
help testing LLVM sub-register code-gen, kernel bpf selftest has much more
C testcases with reasonable size and complexity compared with LLVM
testsuite which only contains unit tests.

There were some file duplication inside BPF_OBJ_FILES_DUAL_COMPILE which
is removed now.

At the moment, all kernel bpf objects are listed under BPF_OBJ_FILES.
Listing them manually sometimes causing patch conflict when people are
adding new testcases simultaneously.

It is better to centre all the related source files under a subdir
"progs", then auto-generate the object file list.

From: Jiong Wang @ 2019-02-11 12:01 UTC (permalink / raw)
  To: alexei.starovoitov, daniel; +Cc: netdev, oss-drivers, Jiong Wang

Sub-register mode compilation was enabled only when there are eBPF "v3"
processor supports at both compilation time inside LLVM and runtime inside
kernel.

Given separation betwen build and test server could be often, this patch
removes the runtime support criteria.
