Subject: [PATCH, RFC] Dumping expanded MD files
Date: Thu, 22 Nov 2012 17:49:00 -0000 [thread overview]
Message-ID: <CAGs3RfvHEekrCcagF3uvFgsOfW+xLzFyi+RyoEY+qNkNa=-k3w@mail.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1004 bytes --]
Hi folks,
This patch adds an utility for dumping MD-files after iterators and
define_substs expanding. The new utility is named genmddump and is
built along with other gen* programs.
I also added new target to Makefile to invoke this utility. However,
I’m not sure it’s general enough to be added to the top-level
makefile, so your suggestions on where we should place it and how it
should be invoked are welcome.
ChangeLog
2012-11-22 Michael Zolotukhin <michael.v.zolotukhin@intel.com>
* Makefile.in: Add targets mddump and mddump-gcc for dumping expanded
MD-files.
gcc/ChangeLog
2012-11-22 Michael Zolotukhin <michael.v.zolotukhin@intel.com>
* Makefile.in: Add targets s-mddump, build/genmddump.o. Extend
genprogrtl with mddump.
* genmddump.c: New.
* gensupport.c (dump_rtl_queue): New.
(dump_expanded_md): New.
* gensupport.h: Declare dump_expanded_md.
What do you guys think?
Thanks, K
