error: no memory region specified for loadable section `.rodata'

Hi!

evbsh3 kernels don't build now, failing with the following error.  How
should I fix this?

Update ldscripts? (add "*(.rodata)" after "*(.text)" or so?)

Hi.

I could fix this problem after I found evbsh3 is built as COFF. :-)

I'm preparing changes to evbsh3 so that kernels can be built again.
I'll post patches later.

Killing linker script in NetBSD/sh3

Hi!

This patch kills linker script along with converting evbsh3 from COFF
to ELF.  This fixes evbsh3 kernel build which has been broken for a
while.

Note I set default TEXTADDR to 0x8c010000 on evbsh3, which differs
from that of hpcsh, 0x8c001000.

I tested COMPUTEXEVB.  I need feedback from hpcsh users.

TIA,
Masao

Re: Killing linker script in NetBSD/sh3

(Only to port-sh3, because this is sh3 generic.)

This is a simplified (don't disturb irrelevant parts) version of
previous, plus converting all sh3 ports (dreamcast and mmeye were
missed).

Each port defines default TEXTADDR as DEFTEXTADDR.  If each kernel
config doesn't define TEXTADDR, DEFTEXTADDR is used.  This is what
other ports are doing. LINKFLAGS_NORMAL=-X is most ports are use too.

Tested only on COMPUTEXEVB (evbsh3).

As you eliminate LDSCRIPTBASE usage from the makefile, why keep it in
the config?  (here and in all other ports).

I'd say - commit it.  If there is any fallout from this in some ports,
we can deal with it in the tree.

Thanks.

SY, Uwe
