New Revision: 264345
URL: http://svnweb.freebsd.org/changeset/base/264345
Log:
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.

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.

The nve(4) driver has been removed. Please use the nfe(4) driver
for NVIDIA nForce MCP Ethernet adapters instead.
