IA-64 Processor-Status-Register (PSR) Bit Names

The assembler defines bit masks for each of the bits in the IA-64 processor status register. For example, ‘ psr.ic ’ corresponds to a value of 0x2000. These masks are primarily intended for use with the ‘ ssm ’/‘ sum ’ and ‘ rsm ’/‘ rum ’ instructions, but they can be used anywhere else where an integer constant is expected.
