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 --- 2014-02-12 James Greenhalgh <james.greenha...@arm.com> * config/arm/aarch-common-protos.h (alu_cost_table): Fix spelling of "extend". * config/arm/arm.c (arm_new_rtx_costs): Fix spelling of "extend".
