From 1398a81618e18405afaeb31197929df2dd1cf5f4 Mon Sep 17 00:00:00 2001 From: Giacomo Travaglini Date: Mon, 18 Nov 2019 13:50:02 +0000 Subject: arch-arm: Fix NumVecV7ArchRegs value (64->16) In armv7 there are 16 only quadword (vector) registers which are usable by SIMD instructions (Q0-Q15). Those completely overlap with the 32 double word registers (D0-D31). NumVecV7ArchRegs = 16; // Q0-Q15 Change-Id: Id8fee1064d60dcfa54f273fa7d579a20c0087835 Signed-off-by: Giacomo Travaglini Reviewed-by: Nikos Nikoleris Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/23105 Tested-by: kokoro --- src/arch/arm/registers.hh | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/arch/arm/registers.hh b/src/arch/arm/registers.hh index 7f6309bea..f2dfce425 100644 --- a/src/arch/arm/registers.hh +++ b/src/arch/arm/registers.hh @@ -88,8 +88,8 @@ const int NumMiscRegs = NUM_MISCREGS; // Vec, PredVec const int NumFloatV7ArchRegs = 64; -const int NumVecV7ArchRegs = 64; -const int NumVecV8ArchRegs = 32; +const int NumVecV7ArchRegs = 16; // Q0-Q15 +const int NumVecV8ArchRegs = 32; // V0-V31 const int NumVecSpecialRegs = 8; const int NumVecIntrlvRegs = 4; const int NumVecRegs = NumVecV8ArchRegs + NumVecSpecialRegs + NumVecIntrlvRegs; -- cgit v1.2.3
