Amend r263891, by making clang default to DWARF2 debug info format for
all FreeBSD versions, not just 10.x and earlier. Apparently too many people seem to have trouble with post-1993 formats. Also remove the related notes about messing with kernel configuration files from UPDATING, which are now superfluous. Requested by: many MFC after: 3 days

It is no longer necessary to include the dwarf version in your DEBUG

placed in the config file has bene fixed. DEBUG should now just

contain -g. The build system will automatically update things

to do the right thing. Ignore the entry from 20140216.

Clang and llvm have been upgraded to 3.4 release.
|
||||
|
||||
Please note that clang 3.4 now defaults to DWARF4 debug information
|
||||
format when you specify -g. Since kgdb(1) only supports DWARF2, you
|
||||
should update any customized kernel configurations which include debug
|
||||
information to explicitly use -gdwarf-2, e.g:
|
||||
|
||||
makeoptions DEBUG=-gdwarf-2
|
||||
|
||||
This has already been applied to the appropriate GENERIC configuration
|
||||
files, so if you inherit from those, no changes are required.

Please note: this bug has been fixed, please see 20140325.
