33 // General branch target alignment considerations
34 //
35 // z/Architecture does not imply a general branch target alignment requirement.
36 // There are side effects and side considerations, though, which may
37 // provide some performance benefit. These are:
38 // - Align branch target on octoword (32-byte) boundary
39 // On more recent models (from z9 on), I-fetch is done on a Octoword
40 // (32 bytes at a time) basis. To avoid I-fetching unnecessary
41 // instructions, branch targets should be 32-byte aligend. If this
42 // exact alingment cannot be achieved, having the branch target in
43 // the first doubleword still provides some benefit.
44 // - Avoid branch targets at the end of cache lines (> 64 bytes distance).
45 // Sequential instruction prefetching after the branch target starts
46 // immediately after having fetched the octoword containing the
47 // branch target. When I-fetching crosses a cache line, there may be
48 // a small stall. The worst case: the branch target (at the end of
49 // a cache line) is a L1 I-cache miss and the next line as well.
50 // Then, the entire target line must be filled first (to contine at the
51 // branch target). Only then can the next sequential line be filled.
52 // - Avoid multiple poorly predicted branches in a row.

57 // describe individual registers and classes of registers within the target
58 // architecture.

62 //----------Architecture Description Register Definitions----------------------
63 // General Registers
64 // "reg_def" name (register save type, C convention save type,
65 // ideal register type, encoding);
66 //
67 // Register Save Types:
68 //
69 // NS = No-Save: The register allocator assumes that these registers
70 // can be used without saving upon entry to the method, &
71 // that they do not need to be saved at call sites.
72 //
73 // SOC = Save-On-Call: The register allocator assumes that these registers
74 // can be used without saving upon entry to the method,
75 // but that they must be saved at call sites.
76 //
77 // SOE = Save-On-Entry: The register allocator assumes that these registers
78 // must be saved before using them upon entry to the
79 // method, but they do not need to be saved at call sites.
80 //
81 // AS = Always-Save: The register allocator assumes that these registers
82 // must be saved before using them upon entry to the
83 // method, & that they must be saved at call sites.
84 //
85 // Ideal Register Type is used to determine how to save & restore a
86 // register. Op_RegI will get spilled with LoadI/StoreI, Op_RegP will get
87 // spilled with LoadP/StoreP. If the register supports both, use Op_RegI.
88 //
89 // The encoding number is the actual bit-pattern placed into the opcodes.

91 // z/Architecture register definitions, based on the z/Architecture Principles
92 // of Operation, 5th Edition, September 2005, and z/Linux Elf ABI Supplement,
93 // 5th Edition, March 2001.
94 //
95 // For each 64-bit register we must define two registers: the register
96 // itself, e.g. Z_R3, and a corresponding virtual other (32-bit-)'half',
97 // e.g. Z_R3_H, which is needed by the allocator, but is not used
98 // for stores, loads, etc.

1772 // instruction. Operands specify their base encoding interface with the
1773 // interface keyword. There are currently supported four interfaces,
1774 // REG_INTER, CONST_INTER, MEMORY_INTER, & COND_INTER. REG_INTER causes an
1775 // operand to generate a function which returns its register number when
1776 // queried. CONST_INTER causes an operand to generate a function which
1777 // returns the value of the constant when queried. MEMORY_INTER causes an
1778 // operand to generate four functions which return the Base Register, the
1779 // Index Register, the Scale Value, and the Offset Value of the operand when
1780 // queried. COND_INTER causes an operand to generate six functions which
1781 // return the encoding code (ie - encoding bits for the instruction)
1782 // associated with each basic boolean condition for a conditional instruction.
1783 //
1784 // Instructions specify two basic values for encoding. Again, a function
1785 // is available to check if the constant displacement is an oop. They use the
1786 // ins_encode keyword to specify their encoding classes (which must be
