From 0e8e1a6d97cc44d47992e40198490f780fbbfd5a Mon Sep 17 00:00:00 2001 From: Kyrylo Tkachov Date: Tue, 28 Apr 2020 16:21:31 +0100 Subject: [PATCH] [arm] Remove +nofp from -mcpu=cortex-m55 options Turns out for consistency with LLVM the +nofp option shouldn't remove ALL of FP and MVE, just the FP part of MVE. This requires more surgery with feature bits so for GCC 10 I'd rather just not support +nofp for -mcpu=cortex-m55 and implement it properly for GCC 11. 2020-04-28 Kyrylo Tkachov * config/arm/arm-cpus.in (cortex-m55): Remove +nofp option. * doc/invoke.texi (Arm Options): Remove -mcpu=cortex-m55 from +nofp option. --- gcc/ChangeLog | 5 +++++ gcc/config/arm/arm-cpus.in | 1 - gcc/doc/invoke.texi | 2 +- 3 files changed, 6 insertions(+), 2 deletions(-) diff --git a/gcc/ChangeLog b/gcc/ChangeLog index 4c298b8c645..905d2b8a2f5 100644 --- a/gcc/ChangeLog +++ b/gcc/ChangeLog @@ -1,3 +1,8 @@ +2020-04-28 Kyrylo Tkachov + + * config/arm/arm-cpus.in (cortex-m55): Remove +nofp option. + * doc/invoke.texi (Arm Options): Remove -mcpu=cortex-m55 from +nofp option. + 2020-04-28 Matthew Malcomson Jakub Jelinek diff --git a/gcc/config/arm/arm-cpus.in b/gcc/config/arm/arm-cpus.in index 64b8ba70507..728be500b80 100644 --- a/gcc/config/arm/arm-cpus.in +++ b/gcc/config/arm/arm-cpus.in @@ -1509,7 +1509,6 @@ begin cpu cortex-m55 tune flags LDSCHED architecture armv8.1-m.main+mve.fp+fp.dp isa quirk_no_asmcpu - option nofp remove ALL_FP MVE_FP costs v7m vendor 41 end cpu cortex-m55 diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi index 04b84e3a10e..fed38e88ae5 100644 --- a/gcc/doc/invoke.texi +++ b/gcc/doc/invoke.texi @@ -18841,7 +18841,7 @@ Disables the floating-point and SIMD instructions on @samp{cortex-a8}, @samp{cortex-a9}, @samp{cortex-a12}, @samp{cortex-a15}, @samp{cortex-a17}, @samp{cortex-a15.cortex-a7}, @samp{cortex-a17.cortex-a7}, @samp{cortex-a32}, @samp{cortex-a35}, -@samp{cortex-a53},@samp{cortex-a55} and @samp{cortex-m55}. +@samp{cortex-a53} and @samp{cortex-a55}. @item +nofp.dp Disables the double-precision component of the floating-point instructions -- 2.30.2
