Hi,
In aarch-common-protos.h we define a field in alu_cost_table:
"extnd"
On its own this is an upsetting optimization of the
English language, but this trouble is compounded by the
comment attached to this field throughout the cost tables
themselves:
/* Extend. */
This patch fixes the spelling of extend to match that in the
commemnts.
I've checked that AArch64 and AArch32 build with this patch
applied.
OK for trunk/stage-1 (I don't mind which)?
Thanks,
James
