Hi Folks,
I noticed recently that several program under scripts/ implement their own set
of gperf/lex/yacc rules. The following patchset aims at factoring all these
targets into `scripts/Makefiles.lib'. Patches do the job for `genksyms' and
`kconfig', `dtc' remains to be done.
I am not really happy with the file naming, in particular the lexer which breaks
convention. I would prefer something ala:
- parser: %.tab.c
- lexer: %.lex.c
- hash: %.hash.c
Moreover, I'd prefer to build the lexer and parser as a different compilation
unit, but that might be done later on.
The following also allows to automatically regen the %_shipped file upon
modification of its associated prerequiresite, provided REGENERATE_PARSERS is
defined.
The diff may look mistakenly large as I had to shuffle things around to make
them match the same pattern.
Known issue: there should be 2 new warnings introduced in `genksyms', only
compile tested so far (only on tools, not on the full kernel), in particular,
`gperf' options may need to be tuned.
Patches are based on v2.6.38. Not for merge, so not signed off on purpose.
Comments welcome!
