[PATCH 3/4] xtensa: Improve instruction cost estimation and suggestion

2022-06-09 Thread Takayuki 'January June' Suwa via Gcc-patches
This patch implements a new target-specific relative RTL insn cost function because of suboptimal cost estimation by default, and fixes several "length" insn attributes (related to the cost estimation). And also introduces a new machine-dependent option "-mextra-l32r-costs=" that tells implementa
