I'm beginning a project where we want use the OpenRISC ISA with Gem5 (if anybody has been working on this already, please let me know!) and since we are hoping to use both FS and SE modes, my approach plan is to modify the ARM ISA (if that isn't the best idea, please let me know that too). As a starting point, I ran ARM in both SE and FS modes and got errors.
With the command: > scons build/ARM_SE/gem5.opt I got these messages: build/ARM_SE/arch/arm/insts/vfp.cc: In function `uint32_t ArmISA::unsignedRSqrtEstimate(uint32_t)': build/ARM_SE/arch/arm/insts/vfp.cc:849: warning: converting of negative value `-0x00000000000000001' to `uint32_t' build/ARM_SE/arch/arm/insts/vfp.cc: In function `uint32_t ArmISA::unsignedRecipEstimate(uint32_t)': build/ARM_SE/arch/arm/insts/vfp.cc:924: warning: converting of negative value `-0x00000000000000001' to `uint32_t' scons: *** [build/ARM_SE/arch/arm/insts/vfp.o] Error 1 scons: building terminated because of errors. These are the versions I'm using: gcc version 3.4.6 20060404 (Red Hat 3.4.6-9) swig 1.3.31 (I needed an early enough version that pcre wasn't required) python 2.7 scons 2.1.0.alpha.20101125 gem5-stable-b9ba22cb23f2 Any advice on what might be going wrong here? I have no trouble with ALPHA_SE or ALPHA_FS and haven't tried the others.
