Saleem Abdulrasool 27351f2022 ARM: implement support for the UDF mnemonic
The UDF instruction is a reserved undefined instruction space.  The assembler
mnemonic was introduced with ARM ARM rev C.a.  The instruction is not predicated
and the immediate constant is ignored by the CPU.  Add support for the three
encodings for this instruction.

The changes to the invalid instruction test is due to the fact that the invalid
instructions actually overlap with the undefined instruction.  Introduction of
the new instruction results in a partial decode as an undefined sequence.  Drop
the tests as they are invalid instruction patterns anyways.

fp-encoding.txt This patch adds support for FPINST/FPINST2 as operands to vmsr/vmrs. These are optional registers that may be supported some ARM implementations to aid with resolution of floating point exceptions. The manual pages for vmsr and vmrs do not detail their use. Encodings and other information can be found in ARM Architecture Reference Manual section F, chapter 6, paragraph 3. 2013-06-11 09:39:51 +00:00
