Re: Include assembly entry points in TAGS

Re: Include assembly entry points in TAGS

[Peter Chubb]

As it stands, etags doesn't find labels in the IA64 or i386 assembler source 
code, because they're disguised inside a preprocessor macro. 
 
I propose the attached fix, which adds a regular expression to enable 
labels disguised by ENTRY() and GLOBAL_ENTRY() macros. 
 
There's a similar problem for MIPS, which needs to match LEAF(entrypoint)

If you're using Emacs and TAGS, it's useful to be able to get the
global assembler variables as tags into the TAGS file.  But they're
hidden by a macro.  This patch teaches etags about the macro.

There's also NESTED.  I don't use etags, so I won't try to cook a patch.
