From: Aleksandar Markovic <amarko...@wavecomp.com>
v3->v4:
- added support for nanoMIPS user mode functionality and
configuration
- DSP patch split into three for easier review and handling
- corrected indentation in all decoding engine patches
- shift/mask replaced with equivalent extract32() in some
patches
- added missing default cases in some patches
- refactored invocation logic aroung decode_nanomips_opc()
- improved comments before decode_gpr_XXX() utilities
- all four decode_gpr_XXX() are now in a single patch
- two patches on updating BadInstr and related registers
are now merged, and execution logic improved
- minor formatting corrections
- rebased to the latest code
v2->v3:
- added support for nanoMIPS-specifics in ELF headers
- added support for CP0 Config0.WR bit
- updated I7200 definition
- improved indentation of some switch statements
- slight reorganization of patches (splitting, order)
- rebased to the latest code
v1->v2:
- added DSP ASE support
- added MT ASE support
- added GDB XML support
- order of patches changed
- commit messages and patch title improved accross the board
- obsolete email addresses for authors and cosigners replaced
with the right ones
- some functions renamed to reflect better the documentation
- some macros renamed to reflect better their nanoMIPS nature
- streamlined formatting
- some of other reviewer's comments addressed, but the majority
was not; this is because the focus of this version was on
completing the functionality as much as possible; remaining
comments will be addressed in the subsequent versions of this
series
This series of patches implements recently announced nanoMIPS on QEMU.
nanoMIPS is a variable length ISA containing 16, 32 and 48-bit wide
instructions. It is designed to be portable at assembly level with
other MIPS and microMIPS code, but contains a number of changes that
enhance code density and efficiency. The largest portion of patches
is nanoMIPS decoding engine.
