Hello Maintainers:
I want to consult, whether arch-v10 supports $dtp0 register:
- Kernel has already used it in arch/cris/arch-v10/kernel/kgdb.c.
- But upstream gas 2.25.51 can not recognize it for arch-v10, for the
same kgdb.s file which contents $dtp0:
"/upstream/release-cris/bin/cris-gchen-linux-as ./kgdb.s -o kgdb.o" will
be ok.
"/upstream/release-cris/bin/cris-gchen-linux-as --march=v10 ./kgdb.s -o
kgdb.o" will cause "Error: Illegal operands".
For me, I guess, it is upstream toolchain's issue, but I have no the
related ISA documentations (common ISA and v10 special ISA), so at
present I can not be sure about it (related informations are welcomed).
And after this issue, excluding warnings, the cris next-20150702 can
pass allmodconfig with the current latest upstream master branch
toolchain. :-)
Welcome any ideas, suggestions and completions.
Thanks.
