Hi,
This patch is a simple fix to allow decompose_address to handle
SCRATCH'es during 2nd scheduler pass. This patch is a prerequisite
for a scheduler improvement that relies on decompose_address to parse
insns.
Bootstrapped and regtested on x86_64-linux-gnu and regtested on
arm-linux-gnueabihf and aarch64-linux-gnu.
I'd like to see some further discussion here.
get_base_term is supposed to look at its argument as a base address.
I'm curious under what circumstances you want to have a SCRATCH as a
base address?
I didn't see anything in patch #8 which obviously dependended on this,
but maybe it's in there, but more subtle than expected.
If you can justify why it's useful to handle scratch in here, then the
patch will be fine.
