Finding C and assembler tags by regexps only

Hi,


As Subject Says, I'M Looking For A Method To Find Tags In C- And
Assembler-Sources By Using Only Regular Expressions. Is This
Possible? If Not, Are There Good Suboptimal Regexp Solutions?


Etags Uses, At Least For C-Code, More Program Logic Than Only Regexp
Search. Emacs' Cc-Mode Imenu-Support Seems To Be Broken ( At Least It
Finds Tags Within Comments Which Is Not Exactly What I Want ;).
That'S Why I Want To Write My Own Imenu-Support For Cc-Mode ( And
Asm-Mode, Esp. For X86 Intel Syntax, Cause This One Doesn'T Support
Imenu At All In My Emacs Version ).


Tags Could Be:


* In C-Code: ( Global ) Variable Definitions, Type Declarations (
Typedef, Struct, Enum Etc. ), Function Definitions, Preprocessor
Constants (?), Externals (?) Etc.


* In Assembler-Code: Similar To C-Code


Are There (F)Lex Scanners That Can Find Those Tags? Do You Know About
Other Regexp-Only Solutions? Any Suggestions?

[The only completely reliable way to find all the tags in C code is to
parse it, and even then you'll miss the tags inside #if branches that
happen not to be taken. But I'd think that you could do pretty well
with regexps. -John]
