src/sys/libkern, branch releng/14.2 FreeBSD source tree arm64: Mark the armv8 crc32c as supporting BTI 2024-02-19T13:17:47+00:00 Andrew Turner andrew@FreeBSD.org 2023-11-14T15:01:58+00:00 e7d2a96f4f9bf579e5fde5870772a39fb6ffac2a This is built into a test so needs the BTI elf note for the rest of the test to be built with BTI support enabled. As the assembly uses the ENTRY macro it already supports BTI, so mark it as such.
