Hi All,
I'm adding a new feature support, called constant extenders, for the
Hexagon backend. Please find attached the patch file for the same. This
feature enables the Hexagon target to encode a 32-bit immediate value in
an instruction. Once constant extended, an instruction takes 2 instruction
words in the packet. This patch modifies the existing instruction
patterns. It also adds a new Hexagon specific pass which optimizes usage
of the constant extended instructions by converting them into their
non-extended form.
Thanks,
Jyotsna
