From 27c262735cb6d33b01e21e1f3ba73a32965024b9 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Mon, 4 Nov 2019 15:05:18 -0800 Subject: [PATCH] arm: Set the number of FloatRegs to zero. ARM no longer uses the floating point register file and uses the vector registers instead. This avoids checkpointing a bunch of unused registers, making it hard to tell where floating point instructions are keeping their values, etc. Change-Id: I23145ba750f1dd9ff5b815395e073c410120840d Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/22524 Reviewed-by: Giacomo Travaglini Maintainer: Giacomo Travaglini Tested-by: kokoro --- src/arch/arm/registers.hh | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/src/arch/arm/registers.hh b/src/arch/arm/registers.hh index 75945ad81..a97a4ce25 100644 --- a/src/arch/arm/registers.hh +++ b/src/arch/arm/registers.hh @@ -83,14 +83,13 @@ const int NumIntArchRegs = NUM_ARCH_INTREGS; // The number of single precision floating point registers const int NumFloatV7ArchRegs = 64; const int NumFloatV8ArchRegs = 128; -const int NumFloatSpecialRegs = 32; const int NumVecV7ArchRegs = 64; const int NumVecV8ArchRegs = 32; const int NumVecSpecialRegs = 8; const int NumVecIntrlvRegs = 4; const int NumIntRegs = NUM_INTREGS; -const int NumFloatRegs = NumFloatV8ArchRegs + NumFloatSpecialRegs; +const int NumFloatRegs = 0; // Float values are stored in the VecRegs const int NumVecRegs = NumVecV8ArchRegs + NumVecSpecialRegs + NumVecIntrlvRegs; const int VECREG_UREG0 = 32; const int NumVecPredRegs = 18; // P0-P15, FFR, UREG0 -- 2.30.2
