From aa9d6768914c95b9f24fe7eebe6b1e0f4b07f171 Mon Sep 17 00:00:00 2001 From: Chris Demetriou Date: Tue, 4 Jun 2002 01:35:23 +0000 Subject: 2002-06-03 Chris Demetriou * sim-main.h (Nan, Infinity, Less, Equal, AbsoluteValue, Negate) (Add, Sub, Multiply, Divide, Recip, SquareRoot): Move lower in file, remove PARAMS from prototypes. (value_fpr, store_fpr, convert): Likewise. Use SIM_STATE to provide simulator state arguments. (ValueFPR, StoreFPR, Convert): Move lower in file. Use SIM_ARGS to pass simulator state arguments. * cp1.c (SD): Redefine as CPU_STATE(cpu). (store_fpr, convert): Remove 'sd' argument. (value_fpr): Likewise. Convert to use 'SD' instead. --- sim/mips/ChangeLog | 13 +++++++++++++ sim/mips/cp1.c | 13 +++++-------- sim/mips/sim-main.h | 46 ++++++++++++++++++++++++---------------------- 3 files changed, 42 insertions(+), 30 deletions(-) (limited to 'sim') diff --git a/sim/mips/ChangeLog b/sim/mips/ChangeLog index 0fbed2b3091..399827d9268 100644 --- a/sim/mips/ChangeLog +++ b/sim/mips/ChangeLog @@ -1,3 +1,16 @@ +2002-06-03 Chris Demetriou + + * sim-main.h (Nan, Infinity, Less, Equal, AbsoluteValue, Negate) + (Add, Sub, Multiply, Divide, Recip, SquareRoot): Move lower in + file, remove PARAMS from prototypes. + (value_fpr, store_fpr, convert): Likewise.
