Now compiler-rt has been updated in r276851, bring in the various sanitizer libraries that already work on FreeBSD: * asan: Address Sanitizer * ubsan: Undefined Behavior Sanitizer * profile: Profile Guided Optimization support Please note that these libraries are experimental at this stage, so the main Makefile is not yet connected to the build. Since I didn't want to needlessly edit BSD.usr.dist, you will also have to create the install directory /usr/lib/clang/3.5.0/lib/freebsd manually for now. 2015-01-08 22:40:56 +00:00			`# $FreeBSD$`

Use bsd.compiler.mk instead of src.opts.mk - MK_PROFILE is controlled in bsd.opts.mk, which is pulled in via bsd.own.mk, which is pulled in via bsd.init.mk . All upstream Makefiles which build off of this one use bsd.init.mk. - COMPILER_{TYPE,VERSION} is set via bsd.compiler.mk . This reduces the namespace pollution/complexity somewhat.

Correct the detection of hard float arm * Don't test MACHINE, it's irrelevant to userland and should never be used in userland Makefiles. * If we match armv[67] and CPUTYPE is undefined OR it doesn't have 'soft' in it, choose armhf. * Add a note that the soft float on armv[67] may be broken.

Make the assignment of CRTARCH conditional, even in the armhf case, and slightly rework the .if statement. While here, fix a minor typo. 2017-12-02 17:39:04 +00:00			`# CPUTYPE matching soft. This variant may not actually work though.`
Redo r325502 :U:Mfoo expands to :Mfoo, apparently. Explicit check for CPUTYPE being defined, and test for it's value not containing soft before calling CRTARCH armhf. Tested, somewhat. Unfortunately recent changes appear to have affected cross-builds where it no longer works, per my tests after universe12a being upgraded from 07/2017 to 11/2017 sources (DESTDIR isn't being used in WORLDTMP; MK_SYSTEM_COMPILER might be causing issues right now).
