2018-01-27base: Get bitunions to compile on clang 3.8.Gabe Black
clang was getting very upset and interpretting a member function pointer as a call to the actual underlying function, and then complaining that it was a non-static function call without an instance. It seems what it was really upset about was that the class who's scope the member function pointer belonged to (the current class) wasn't done being defined. This *should* be ok as far as I can tell, but clang was having none of it. This change reworks how the type of the setter function arguments are determined to work around that limitation. The bitunion test was run with clang++ and g++ and both pass, and I've built gem5.opt for ARM successfully.

Since this type is now accessible through a clean interface, hide it from anybody that tries to peak around the curtain.

2018-01-20arm, base: Generalize and move the BitUnion hash struct.Gabe Black
The ARM types.hh file defined an STL style hash structure to operate on the ExtMachInst, but it referred to the underlying storage type using internal typedefs in the BitUnion types. To avoid having to do that, this change adds a hash structure to bitunion.hh which will work on any BitUnion, and gets rid of the ARM ExtMachInst version.

2018-01-20base: Rework bitunions so they can be more flexible.Gabe Black
They are now oriented around a class which makes it easy to provide custom setter/getter functions which let you set or read bits in an arbitrary way. Future additions may add the ability to add custom bitfield methods, and index-able bitfields.

2016-11-09style: [patch 3/22] reduce include dependencies in some headersBrandon Potter
Used cppclean to help identify useless includes and removed them. This involved erroneously included headers, but also cases where forward declarations could have been used rather than a full include.
2016-01-11scons: Enable -Wextra by defaultAndreas Hansson
Make best use of the compiler, and enable -Wextra as well as -Wall. There are a few issues that had to be resolved, but they are all trivial.
2015-01-07base: Fix assigning between identical bitfields.Gabe Black
If two bitfields are of the same type, also implying that they have the same first and last bit positions, the existing implementation would copy the entire bitfield. That includes the __data member which is shared among all the bitfields, effectively overwritting the entire bitunion. This change also adjusts the write only signed bitfield assignment operator to be like the unsigned version, using "using" instead of implementing it again and calling down to the underlying implementation.
2014-08-26base: Add a static assert to check bit union rangesAndreas Sandberg
If a bit field in a bit union specified as Bitfield<LSB, MSB> instead of Bitfield<MSB, LSB> the code silently fails and the field is read as zero. This changeset introduces a static assert that tests, at compile time, that the bit order is correct.
