It starts by changing decodetree.py to support 64-bit instructions as well as custom variable-width instruction load functions. Then it changes the target/ppc code to allow 32- and 64-bit instructions to be decoded using decodetree, and finishes by adding the implementation for 2 simple instructions to demonstrate the new approach: - addi (replacing the legacy implementation) - paddi (new) Luis Pires (5): decodetree: Add support for 64-bit instructions decodetree: Fix empty input files for varinsnwidth decodetree: Allow custom var width load functions target/ppc: Base changes to allow 32/64-bit insns target/ppc: Implement paddi and replace addi insns docs/devel/decodetree.rst | 5 +- scripts/decodetree.py | 55 ++++-- target/ppc/cpu.h | 1 + target/ppc/meson.build | 5 + target/ppc/ppc.decode | 26 +++ target/ppc/translate.c | 206 +++++++++++++++------ target/ppc/translate/fixedpoint-impl.c.inc | 26 +++ 7 files changed, 250 insertions(+), 74 deletions(-) create mode 100644 target/ppc/ppc.decode create mode 100644 target/ppc/translate/fixedpoint-impl.c.inc
