package/rocksdb: bump to version 6.13.3 - Refresh first patch - Replace second patch (this new iteration of previous patch has not been merged and does not apply cleanly on current version) - Update hash of README.md (CircleCI gadget added with https://github.com/facebook/rocksdb/commit/63b59f21d9971fc941e3ee2244783a3c16bd5ad4) - LTO is supported since version 6.12.6 and https://github.com/facebook/rocksdb/commit/c0c33a4854587e412742841f199edd4616be6c00 - DESTDIR and PREFIX are supported since version 6.13.2 and https://github.com/facebook/rocksdb/commit/1e59800718b29d4a762b8ac356767a701f968a4d https://github.com/facebook/rocksdb/releases/tag/v6.13.3 Fixes: - http://autobuild.buildroot.org/results/a9798bb279a668a266c472fb026b68dbccf50431 Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

Subject: [PATCH] POWER7/8 compatiblity fix + CRC32 C implementation
When running on a POWER7/8, the compiler will successfully
report being able to compile for POWER9 compatibility. It will
however fail to run due to POWER9+ only instructions being used.
To preserve the goals of ensuring an optimization for the
local hardware, -mcpu=native is used, but only if we don't
already have C{,XX}_FLAGS with cpu/arch/tune set. PORTABLE
flag that was added for x86 is reused to ensure that the minimum
viable cpu is selected, POWER7 if compiling on big endian and
POWER8 if on little endian.
This ensures that if a binary distributor compiles on a
POWER9, and aims to support POWER8 packages, then hopefully
they will have the correct C{,XX}_FLAGS, and as such, will
not result in a broken package on POWER8.
Fixes: 8fc20ac468b266a53083175025375985ec04b796
We also replace POWER crc32c with C implementation.
The presence of clang compile failures on POWER due to
missing ppc-asm.h prompted the replacement of the ASM
CRC32 implementation with the C implementation.
We include this when the compile flags enable it to be build.
For example on POWER7 the optimized crc32 will be built,
however it won't be used because of the runtime detection.
If the executable is moved to a POWER8 big endian it will
work correctly.
https://github.com/antonblanchard/crc32-vpmsum/blob/master/vec_crc32.c
is used with only small include path change with the local copyright header
maintained.
util/crc32c.cc removes arch_ppc_crc32 which was only ever
used in a local context. Also incorporated significant advice from
tchaikov in #2869. Replace all compile time checks with runtime checks.
Corrects getauxval detection from 8bbd76edbf by including the header from the
right directory.
