Gabe Black d63f748b53 ARM: Implement ADR as separate from ADD. 2010-06-02 12:58:04 -05:00
Gabe Black e92dc21fde ARM: Add support for interworking branch ALU instructions. 2010-06-02 12:58:04 -05:00
Gabe Black 11c3361be4 ARM: Fix when the flag bits are updated for thumb. 2010-06-02 12:58:04 -05:00
Gabe Black 14d25fbad0 ARM: Don't rely on undefined behavior to get arithmetic right shift.
Shifting to the right of a signed value when the MSB is one is technically
undefined behavior, even though in my experience it's done the "right thing"
and sign extended the value. This replaces the arithmetic right shift code in
ARM that uses that coincidence with some code that relies on bit math.

Gabe Black 05d880f7a1 ARM: Restrict the shift amount from a register to 8 bits.
The shift amount when taken from a register is supposed to be truncated to an
8 bit value.

Gabe Black b02c7f1bcd ARM: Move the macro mem constructor out of the isa desc.
This code doesn't use the parser at all, and moving it out reduces the
conceptual complexity of that code.
2010-06-02 12:58:03 -05:00
Gabe Black 7b62e9ad71 ARM: Make macroops panic if executed directly.
The macroop should never be executed, only it's microops will.
