2017-12-04base: Rework the trie dump function to accept a different ostream.Gabe Black
It might often be useful to write output to cout when dumping a trie, but sometimes it might be useful to dump ot to something else like a string stream instead.

2017-12-04tests: Remove trietest's dependence on cprintf.Gabe Black
Dumping the structure of the tries being constructed was useful for debugging when the trie data structure was being developed, but the output can't be automatically verified easily, and what's considered correct depends on the specific implementation of the trie itself. To make some of the earlier tests more meaningful, additional lookups were added which verified that the correct values were returned when the nodes of the trie were in particular arrangements.

2017-12-01arm: Enable ns registers access in secure modeGiacomo Travaglini
Arm security extension introduced register banking between secure and non-secure mode. This has been removed in armv8 using AArch64 in EL3, where the decoded register is by default the non-secure version. Using non-secure register infos(flags) was preventing secure execution to access the register with the MRC/MCR at EL1. The patch updates the following banked registers' flags so that their non-secure version can be accessed in secure mode: MISCREG_CSSELR, MISCREG_SCTLR, MISCREG_ACTLR, MISCREG_TTBR0, MISCREG_TTBR1, MISCREG_TTBCR, MISCREG_DACR, MISCREG_DFSR, MISCREG_IFSR, MISCREG_ADFSR, MISCREG_AIFSR, MISCREG_DFAR, MISCREG_IFAR, MISCREG_PAR, MISCREG_PRRR, MISCREG_MAIR0, MISCREG_NMRR, MISCREG_MAIR1, MISCREG_AMAIR0, MISCREG_AMAIR1, MISCREG_VBAR, MISCREG_CONTEXTIDR, MISCREG_TPIDRURW, MISCREG_TPIDRURO, MISCREG_TPIDRPRW, MISCREG_CNTP_TVAL, MISCREG_CNTP_CTL, MISCREG_CNTP_CVAL For those registers the following permission bits have been set: MISCREG_PRI_S_RD MISCREG_PRI_S_WR Change-Id: Ib881c526e75d69e313f8ef66eb78fc704de6bf59 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-by: Giacomo Gabrielli <giacomo.gabrielli@arm.com> Reviewed-on: https://gem5-review.googlesource.com/6201 Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>

2017-11-27scons: Switch from "guards" to "tags" on source files.Gabe Black
Tags are just arbitrary strings which are attached to source files which mark them as having some property. By default, all source files have the "gem5 lib" tag added to them which marks them as part of the gem5 library, the primary component of the gem5 binary but also a seperable component for use in, for example, system C. The tags can be completely overridden by setting the "tags" parameter on Source, etc., functions, and can be augmented by setting "add_tags" which are tags that will be added, or alternatively additional tags. It's possible to specify both, in which case the tags will be set to the union of tags and add_tags. add_tags is supposed to be a way to add extra tags to the default without actually overriding the default. Both tags and add_tags can be a list/tuple/etc of tags, or a single string which will be converted into a set internally. Other existing tags include: 1. "python" for files that need or are used with python and are excluded when the --without-python option is set 2. "main" for the file(s) which implement the gem5 binary's main function. 3. The name of a unit test to group its files together. 4. Tags which group source files for partial linking. By grouping the "tags" into a single parameter instead of taking all extra parameters as tags, the extra parameters can, in the future, be passed to the underlying scons environment. Also, the tags are either present or not. With guards, they could be present and True, present and False, or not present at all.

2017-11-22sparc: Move the microop/macroop base classes out of the ISA desc.Gabe Black
These were just raw C++ classes. Change-Id: Id2101400d885c6938efb6b94f2949722cfbb94ae Reviewed-on: https://gem5-review.googlesource.com/5481 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2017-11-22sparc: Return debug faults from unimplemented instructions.Gabe Black
These had been marked as non-speculative so that their execute functions would only be called if the instruction should really be executed. Instead, we can return faults which will cause the same behavior when the instruction is committed and let the instruction execute as normal.

2017-11-22sparc: Pull the unimplemented formats out of the ISA description.Gabe Black
These are simple classes which don't need to be in the ISA description. Change-Id: Ia0bb45f50c4da2536855efcb3c17c7780b431332 Reviewed-on: https://gem5-review.googlesource.com/5464 Reviewed-by: Gabe Black <gabeblack@google.com> Maintainer: Gabe Black <gabeblack@google.com>
2017-11-22sparc: Pull the "Uknown" StaticInst class out of the ISA description.Gabe Black
The only thing the Unknown format does is return an instance of this class, so there's no reason to have it in the ISA description.

2017-11-22sparc: Pull most of the Nop format out of the ISA description.Gabe Black
The Nop format mostly just made instructions that inherited from the Nop base class but with different mnemonics, so there doesn't need to be very much dynamic content.
