[Qemu-devel] [PATCH v3 31/38] target-microblaze: Simplify address computation using tcg_gen_addi_i32()

[Edgar E. Iglesias]

From: "Edgar E. Iglesias" <address@hidden>

Simplify address computation using tcg_gen_addi_i32().
tcg_gen_addi_i32() already optimizes the case when the
immediate is zero.

No functional change.
