From 689c2b4b65fb5d0ce6b6414685e1f5c6f97d7c25 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 10 Nov 2022 15:53:25 +0700 Subject: [PATCH] sim: ppc: rename ppc-instructions to powerpc.igen To make it clear this is an input to the igen tool, rename it with an igen extension. This matches the other files in the ppc dir (altivec & e500 igen files), and the other igen ports (mips, mn10300, v850). --- sim/ppc/BUGS | 2 +- sim/ppc/INSTALL | 6 +++--- sim/ppc/Makefile.in | 4 ++-- sim/ppc/{ppc-instructions => powerpc.igen} | 0 4 files changed, 6 insertions(+), 6 deletions(-) rename sim/ppc/{ppc-instructions => powerpc.igen} (100%) diff --git a/sim/ppc/BUGS b/sim/ppc/BUGS index 362b079e90c..300c79120ce 100644 --- a/sim/ppc/BUGS +++ b/sim/ppc/BUGS @@ -15,7 +15,7 @@ VEA: Missing VEA system calls. -ppc-instructions: +powerpc.igen: Missing or commented out instructions. diff --git a/sim/ppc/INSTALL b/sim/ppc/INSTALL index 9feac7b9e61..22ead08de5f 100644 --- a/sim/ppc/INSTALL +++ b/sim/ppc/INSTALL @@ -218,7 +218,7 @@ With just --enable-sim-warnings, the following -W options are enabled: Specify the file containing the rules for generating the instruction -decode and execute functions from the file ppc-instructions. +decode and execute functions from the file powerpc.igen.
