libc: centralize a few numeric symbolsfabs, __infinity, and __nan are universally implemented so declare themin gen/Symbol.map.We would also include __flt_rounds, but it's under FBSD_1.3 on arm sountil that's gone we're stuck with it.

16d5f9a1649e6a3e5841c6c41d6af9430ed9f064 - Add an implementation of .mcount on arm64

Tue, 22 Mar 2022 16:46:15 +0100

Add an implementation of .mcount on arm64To support cc -pg on arm64 we need to implement .mcount. As clang andgcc think it is function like it just needs to load the argumentsto _mcount and call it.On gcc the first argument is passed in x0, however this is missing onclang so we need to load it from the stack. As it's the caller returnaddress this will be at a known location.PR: 262709Reviewed by: emaste (earlier version)Sponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D34634 List of files: /freebsd/lib/libc/aarch64/Symbol.map

94098ab7c36ea60863f431e9cd5c95b19e854835 - Remove brk and sbrk from arm64. They were defined in The Single UNIX

Fri, 20 May 2016 17:04:48 +0200

Remove brk and sbrk from arm64. They were defined in The Single UNIXSpecification, Version 2, but marked as legacy, and have been removed fromlater specifications. After 12 years it is time to remove them from newarchitectures when the main use for sbrk is an invalid method to attemptto find how much memory has been allocated from malloc.There are a few places in the tree that still call sbrk, however they arenot used on arm64. They will need to be fixed to cross build from arm64,but these will be fixed in a follow up commit.Old copies of binutils from ports called into sbrk, however this has beenfixed around 6 weeks ago. It is advised to update binutils on arm64 beforeinstalling a world that includes this change.Reviewed by: brooks, emasteObtained from: brooksRelnotes: yesSponsored by: ABT Systems LtdDifferential Revision: https://reviews.freebsd.org/D6464 List of files: /freebsd/lib/libc/aarch64/Symbol.map
