Re: Creating sparc64 installation images
So, I just started right away with silo from git and the build initially
failed with "-m32" which was still in the debian package's
configuration. I used the most recent silo package for "sparc" and
updated the source from git. Then enabled the build for "sparc64" and
removed "-m32" and got this far:
> https://people.debian.org/~glaubitz/silo_1.4.14+git20141019-1.build
gcc -Os -Wall -I. -I../include -fomit-frame-pointer -fno-strict-aliasing
-DSMALL_RELOC=0x280000 -DLARGE_RELOC=0x380000 -fno-stack-protector -c
divdi3.S
divdi3.S: Assembler messages:
divdi3.S:105: Error: detected global register use not covered by
.register pseudo-op
Any suggestions?
Please make sure you have all the patches below applied. They not only
port the assembly from v8+ to v9, but also fix some runtime problems
with sign extensions, structure packing and others.
