1 # S/390 cpu description file
2 # this file is read by genmdesc to pruduce a table with all the relevant information
3 # about the cpu instructions that may be used by the regsiter allocator, the scheduler
4 # and other parts of the arch-dependent part of mini.
5 #
6 # An opcode name is followed by a colon and optional specifiers.
7 # A specifier has a name, a colon and a value. Specifiers are separated by white space.
8 # Here is a description of the specifiers valid for this file and their possible values.
9 #
10 # dest:register describes the destination register of an instruction
11 # src1:register describes the first source register of an instruction
12 # src2:register describes the second source register of an instruction
13 #
14 # register may have the following values:
15 # i integer register
16 # a r3 register (output from calls)
17 # b base register (used in address references)
18 # f floating point register
19 #
20 # len:number describe the maximun length in bytes of the instruction
21 # number is a positive integer
22 #
23 # cost:number describe how many cycles are needed to complete the instruction (unused)
24 #
25 # clob:spec describe if the instruction clobbers registers or has special needs
26 #
27 # spec can be one of the following characters:
28 # c clobbers caller-save registers
29 # r 'reserves' the destination register until a later instruction unreserves it
30 # used mostly to set output registers in function calls
31 #
32 # flags:spec describe if the instruction uses or sets the flags (unused)
33 #
34 # spec can be one of the following chars:
35 # s sets the flags
36 # u uses the flags
37 # m uses and modifies the flags
38 #
39 # res:spec describe what units are used in the processor (unused)
40 #
41 # delay: describe delay slots (unused)
42 #
43 # the required specifiers are: len, clob (if registers are clobbered), the registers
44 # specifiers if the registers are actually used, flags (when scheduling is implemented).
45 #
46 # See the code in mini-x86.c for more details on how the specifiers are used.
