2018-11-07	arch-arm: Remove SCTLR.VE bit	Giacomo Travaglini
	ARMv8 has removed SCTLR.VE bit which is now hardcoded to 0. We are removing it from gem5 since we were not handling it anyway.

2018-10-02	arch-arm: Add FP16 support and other primitives to fplib	Edmund Grimley Evans
	This changeset: - extends fplib to support emulation of half-precision floating-point (FP16) operations; - extends fplib to support additional primitives introduced by the Arm Scalable Vector Extension (SVE) (fplibExpa, fplibScale, fplibTrigMAdd, fplibTrigSMul, fplibTrigSSel); - adds the FZ16 bit to FPSCR; - cleans up fplib code by replacing constants with preprocessor macros and by adding inline functions to recognise NaNs and infinities.

2018-10-01	arch-arm: Implement AArch64 ID regs as bitunions	Giacomo Travaglini
	This patch is implementing the following AArch64 ID registers as bitunions, so that it is easier to query for feature availability: - ID_AA64DFR0_EL1 - ID_AA64ISAR0_EL1 - ID_AA64ISAR1_EL1 - ID_AA64MMFR1_EL1 - ID_AA64MMFR2_EL1 - ID_AA64PFR0_EL1 They are updated to the latest Armv8.5 arch release version. RES0 only ID registers like ID_AA64AFR1_EL1 haven't been added.

2018-10-01	arch-arm: Move MiscReg BitUnions into a separate header file	Giacomo Travaglini
	As the number of MiscRegs increases there is the need of a cleaner header file; this patch is separating miscreg.[cc,hh] where the miscreg decoding/utility functions are defined/declared from the MiscReg register types (BitUnion).
