Subject: axp & (dejagnu | haifa) & redhat-5.0
Date: Tue, 09 Dec 1997 00:46:00 -0000 [thread overview]
Message-ID: <199712090934.CAA05418@jarvi.ezlink.com> (raw)
OK.
I guess I've got two groups questions after following the list for a while.
I see mention that egcs is busted on redhat-5.0, yet I managed to install
it as the native compiler and as multiple cross compilers. Maybe it is
broke and I just dont realize it yet.
1. dejagnu.
After installing a few version I thought it would be nice to start
letting egcs run though the hoops at night. I downloaded the latest
dejagnu package off cygnus, did the (cd dejagnu;./configure;make;
make install) and then jumped back into my egcs build dir and tried the
make -k check.
My trusty hd made huge noises for a while the screen rolled with
info worthy of the daily news and then everything stopped with
WARNING: Couldn't find the global config file.
ERROR: Couldn't find library file utils.exp.
So.. obviously I'm making a stupid mistake. I see the file in the
dejagnu tree. Whats my error?
2. haifa.
From what little I've managed to read this could be fairly interesting.
I managed to build egcs with --enable-haifa. I've played around some.
I'm left wondering whats going on.
a. does a compiler with --enable-haifa use the new schdualing by default?
b. what do these flags do. well never mind that. whats a logical
use of them.
#ifdef HAIFA
{"sched-interblock",&flag_schedule_interblock, 1},
{"sched-spec",&flag_schedule_speculative, 1},
{"sched-spec-load",&flag_schedule_speculative_load, 1},
{"sched-spec-load-dangerous",&flag_schedule_speculative_load_dangerous, 1},
{"sched-reverse-S",&flag_schedule_reverse_before_reload, 1},
{"sched-reverse-R",&flag_schedule_reverse_after_reload, 1},
{"branch-count-reg",&flag_branch_on_count_reg, 1},
#endif /* HAIFA */
c. rth will probably beat me on the head with another clue book.. but
if noticed on the alpha-unknown-linux-gnu the following flags crash
the haifa egcs when building makeinfo in the egcs package.
-fsched-spec-load
-fdelayed-branch
I'd appreciate any feedback.
Trent
