-The attached patch adds native spinlock support to PostgreSQL on RISC-V
-systems. As suspected by Richard W.M. Jones of Red Hat back in 2016, the
-__sync_lock_test_and_set() approach applied on arm and arm64 works here
-as well.
-
-
-Tested against PostgreSQL 13.3 on a physical rv64gc system (BeagleV
-Starlight beta board) - builds and installs fine, all tests pass. From
-what I can see in gcc documentation this should in theory work on rv32
-(and possibly rv128) as well, therefore the patch as it stands covers
-all RISC-V systems (i.e. doesn't check the value of __risc_xlen) - but I
-haven't confirmed this experimentally.
