Re: More recognizing NetBSD CPUs (Super-H, MIPS 64bit)

[coypu]

Hi Ben,

I am only interested in recognizing this case:
shl-unknown-netbsdelf8.99

The bug report to prompt me to make this change is:
http://gnats.netbsd.org/53825

The reason 'shl' is used, is due to this normalization in config.guess:
    *:NetBSD:*:*)
...
                sh3el) machine=shl-unknown ;;
                sh3eb) machine=sh-unknown ;;
                sh5el) machine=sh5le-unknown ;;


>From code inspection, NetBSD/Super-H 'uname -p' will only ever return
'sh3el' or 'sh3eb'.*
I get the impression that the desired normalization would be
'shle' for little-endian and 'sh' for big-endian.
For unclear reason, 'shl' was used instead of 'shle' in config.guess.



GCC handles both:

# Note the 'l'; we need to be able to match e.g. "shle" or "shl".
sh[123456789lbe]*-*-* | sh-*-*)

I was over-eager to change things, being inspired by GCC's config.gcc.




* Super-H 5 / sh64 had a very brief life, and almost no hardware was
made. Although, due to patents expiring, there's renewed interest in
FOSS Super-H variants.
