# ia64 cpu description file
-# this file is read by genmdesc to pruduce a table with all the relevant information
-# about the cpu instructions that may be used by the register allocator, the scheduler
-# and other parts of the arch-dependent part of mini.
#
-# An opcode name is followed by a colon and optional specifiers.
-# A specifier has a name, a colon and a value. Specifiers are separated by white space.
-# Here is a description of the specifiers valid for this file and their possible values.
+# The instruction lengths are very conservative, it doesn't matter on ia64
+# since there are no short branches.
#
-# dest:register describes the destination register of an instruction
-# src1:register describes the first source register of an instruction
-# src2:register describes the second source register of an instruction
-#
-# register may have the following values:
-# i integer register
-# b base register (used in address references)
-# f floating point register
-#
-# len:number describe the maximun length in bytes of the instruction
-# number is a positive integer
-#
-# cost:number describe how many cycles are needed to complete the instruction (unused)
-#
-# clob:spec describe if the instruction clobbers registers or has special needs
-#
-# spec can be one of the following characters:
-# c clobbers caller-save registers
-# r 'reserves' the destination register until a later instruction unreserves it
-# used mostly to set output registers in function calls
-#
-# flags:spec describe if the instruction uses or sets the flags (unused)
-#
-# spec can be one of the following chars:
-# s sets the flags
-# u uses the flags
-# m uses and modifies the flags
-#
-# res:spec describe what units are used in the processor (unused)
-#
-# delay: describe delay slots (unused)
-#
-# the required specifiers are: len, clob (if registers are clobbered), the registers
-# specifiers if the registers are actually used, flags (when scheduling is implemented).
-#
