ppc-opcode.h have base instruction encoding wrapped with stringify_in_c()
for raw encoding to have compatibility. But there are redundant macros for
base instruction encodings in bpf, instruction emulation test infrastructure
and powerpc selftests.
Currently PPC_INST_* macros are used for encoding instruction opcode and PPC_*
for raw instuction encoding, this rfc patchset introduces PPC_RAW_* macros for
base instruction encoding and reuse it from elsewhere. With this change we can
avoid redundant macro definitions in multiple files and start adding new
instructions in ppc-opcode.h in future.
Changes in v1:
-------------
* Drop the patch that had changes in stringloops Makefile.
* Include Acked-by and Tested-by tag from Naveen.
* Rebased on next branch of linuxppc tree.
Changes in rfc v2:
-----------------
Fix review comments/suggestions from Naveen and Michael Ellerman,
* Rename PPC_ENCODE_* to PPC_RAW_* for base instruction encoding macros.
* Split the patches that does mass renaming and make them simpler that just
adds new macros.
* Keep the patch to update all the existing names later (patch 6).
* Lot of PPC_INST_* macros are used only in ppc-opcode.h for PPC_* macros,
fold PPC_INST_* encoding into PPC_RAW_* to avoid using them accidentally.
* Fixed clipped macros that was due to a typo/copy-paste
* Consolidated all the instruction encoding macros from bpf_jit.h to
ppc-opcode.h
* squashed patch that removes the duplicate macro PPC_MR() in bpf_jit.h
* merge few changes in bpf_jit files from patch 2 into patch 3
* few fixes in powerpc selftest stringloops Makefile
* build tested for ppc64le_defconfig, ppc64e_defconfig and pmac32_defconfig
* Rebased on next branch of linuxppc tree
Testing:
-------
* Tested it by compiling vmlinux and comparing objdump of it with and without
the patchset and observed that it remains same,
# diff vmlinux_objdump vmlinux_rfc_objdump
2c2
< vmlinux: file format elf64-powerpcle
---
> vmlinux_rfc: file format elf64-powerpcle
* Tested building it with this changes for Fedora30 config, booted VM
with powerpc next and powerpc next + patchset to run powerpc selftest and
ftrace selftest. There were couple of failures that were common and
patchset did not introduce any new failures.
ftrace selftest:
---------------
# # of passed: 96
# # of failed: 1
# # of unresolved: 7
# # of untested: 0
# # of unsupported: 1
# # of xfailed: 1
# # of undefined(test bug): 0
not ok 1 selftests: ftrace: ftracetest # exit=1
powerpc selftest:
----------------
not ok 7 selftests: powerpc/dscr: dscr_sysfs_thread_test # exit=1
not ok 20 selftests: powerpc/pmu/ebb: lost_exception_test # TIMEOUT
not ok 2 selftests: powerpc/security: spectre_v2 # exit=1
Thanks to Naveen, Sandipan and Michael on overall suggestions/improvements.
I would request for review and suggestions to make it better.

Introduce PPC_RAW_* macros to have all the bare encoding of ppc
instructions. Move `VSX_XX*()` and `TMRN()` macros up to reuse it.

move macro definitions of powerpc instructions from bpf_jit.h to ppc-opcode.h
and adopt the users of the macros accordingly. `PPC_MR()` is defined twice in
bpf_jit.h, remove the duplicate one.

I know you're copying the existing formatting by wrapping these lines,
but please don't.
It hurts rather than improves readability.
For a line like the one above, just let it be long, eg:
#define PPC_RAW_DARN(t, l) (PPC_INST_DARN | ___PPC_RT(t) | (((l) & 0x3) << 16))
Yeah it's 91 columns but who cares.
For the really long ones like:
> +#define PPC_RAW_TLBIE_5(rb, rs, ric, prs, r) \
> + (PPC_INST_TLBIE | \
> + ___PPC_RB(rb) | \
> + ___PPC_RS(rs) | \
> + ___PPC_RIC(ric) | \
> + ___PPC_PRS(prs) | \
> + ___PPC_R(r))
I think this is the best option:
#define PPC_RAW_TLBIE_5(rb, rs, ric, prs, r) \
(PPC_INST_TLBIE | ___PPC_RB(rb) | ___PPC_RS(rs) | ___PPC_RIC(ric) | ___PPC_PRS(prs) | ___PPC_R(r))
Which is long, but I don't think wrapping it helps.
If we didn't have those ridiculous ___PPC_RX macros it would be a bit
shorter, but I guess that's a rework for another day.
cheers

Sorry this series collided with the prefixed instruction support and I
didn't have time to resolve the conflicts.
Can you please rebase on top of current mainline and resend.
cheers
