- New FPROFILE_GENERATE and FPROFILE_USE CMake options are available for experimenting with profile guided optimization (PGO) with GCC. See the cmake/fprofile.cmake in a MySQL source distribution for information about using them. These options have been tested with GCC 8 and 9, and with Clang.
- Enabling FPROFILE_USE also enables WITH_LTO (link time optimization).
- Innodb_system_rows_read, Innodb_system_rows_inserted, Innodb_system_rows_deleted status variables were added for counting row operations on InnoDB tables that belong to system-created schemas. The new status variables are similar to the existing Innodb_rows_read, Innodb_rows_inserted, Innodb_rows_deleted status variables, which count operations on InnoDB tables that belong to both user-created and system-created schemas.
- The new status variables are useful in replication environments where relay_log_info_repository and master_info_repository variables are set to TABLE, resulting in higher row operation counts on slaves due to operations performed on the slave_master_info, slave_replay_log_info, and slave_worker_info tables, which belong to the system-created mysql schema. For a valid comparison of master and slave row operation counts, operations on tables in system-created schemas can now be excluded using the count data provided by the new status variables.

switch patch-files to mysql80-server to make it easy for maintain.
Bugfix:
- CMake now enables use of fastcov if it is available. fastcov is faster than lcov or gcov. This requires GCC and gcov versions of 9 or higher.
- The DISABLE_SHARED CMake option was unused and has been removed.
- The CMake code to find Protobuf executables now works on platforms that split these into multiple packages.
- The new ADD_GDB_INDEX CMake option determines whether to enable generation of a .gdb_index section in binaries, which makes loading them in a debugger faster. The option is disabled by default. It has no effect if a linker other than lld or GNU gold is used.
- For the INSTALL_LAYOUT CMake option, the SLES and WIN option values were not used and have been removed.
- The max_prepared_stmt_count system variable maximum value has been increased from 1 million (1,048,576) to 4 million (4,194,304). The default value remains unchanged at 16,382.
- MySQL 8.0 no longer supports building using wolfSSL. All MySQL builds now use OpenSSL.
- The RE2 library is no longer used by MySQL. The library is no longer bundled with source distributions and the WITH_RE2 CMake option is obsolete.

Upstream notes: https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-13
While here, fix the build with GCC-based architectures too (ported from fix on MySQL57)

Fix build with LibreSSL and OpenSSL-devel ports as well
MySQL 8.0.11 is the General Availability (GA) version of MySQL 8.
MySQL since this version supports FIPS-mode, if compiled using OpenSSL, AND
an OpenSSL library and FIPS Object Module are available at runtime.
FIPS mode imposes conditions on cryptographic operations such as
restrictions on acceptable encryption algorithms or requirements for longer key lengths.
The --ssl-fips-mode client option enables control of FIPS mode on the client side for:
mysql, mysqladmin, mysqlbinlog, mysqlcheck, mysqldump, mysqlimport, mysqlpump, ...
This update includes bugfixes including (not limited to):
-InnoDB: The server was stopped before a fatal error message
was written to the error log.
-InnoDB: An incorrect GROUP BY result was returned when using the
TempTable storage engine and a NO PAD collation.
-InnoDB: The data retrieved from INFORMATION_SCHEMA.INNODB_COLUMNS was
incorrect for tables containing a virtual column.
