From 99575d60c881fccdc0e5c1f433d63d9d9d2ca86d Mon Sep 17 00:00:00 2001 From: Chung-Ju Wu Date: Wed, 3 Sep 2014 10:01:54 +0000 Subject: [PATCH] [NDS32] Since we are going to provide new heuristic for fp-as-gp optimization, we better not to set cfun->machine->fp_as_gp_p at prologue expanding. * config/nds32/nds32.c (nds32_expand_prologue): Suppress fp-as-gp optimization detection.
