Subject: ({low_32_bit,offsettable_mem}_operand): The function low_32_bit_operand is now unused... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8f75773e1fc6ebd96c65db1156afaba4915f40df;p=gcc.git

({low_32_bit,offsettable_mem}_operand): The function low_32_bit_operand is now unused, delete it.

({low_32_bit,offsettable_mem}_operand): The function
low_32_bit_operand is now unused, delete it.  New function
offsettable_mem_operand to determine if a memory address is
offsettable.
(float_conv_temp): New global.
(output_epilog): Zero out float_conv_temp.
