14368 | The required alignment for V.4 is 16 bytes, or 8 bytes if -meabi is |
14369 | given. (But note below and in sysv4.h that we require only 8 and | |
14370 | may round up the size of our stack frame anyways. The historical | |
14371 | reason is early versions of powerpc-linux which didn't properly | |
14372 | align the stack at program startup. A happy side-effect is that | |
14373 | -mno-eabi libraries can be used with -meabi programs.) | |
14374 | ||
50d440bc | 14375 | The EABI configuration defaults to the V.4 layout. However, |
5376a30c KR |
14376 | the stack alignment requirements may differ. If -mno-eabi is not |
14377 | given, the required stack alignment is 8 bytes; if -mno-eabi is | |
14378 | given, the required alignment is 16 bytes. (But see V.4 comment | |

17088 | /* A C compound statement that outputs the assembler code for a thunk |
17089 | function, used to implement C++ virtual function calls with | |
17090 | multiple inheritance. The thunk acts as a wrapper around a virtual | |
17091 | function, adjusting the implicit object parameter before handing | |
17092 | control off to the real function. | |
17093 | ||
17094 | First, emit code to add the integer DELTA to the location that | |
17095 | contains the incoming first argument. Assume that this argument | |
17096 | contains a pointer, and is the one used to pass the `this' pointer | |
17097 | in C++. This is the incoming argument *before* the function | |
17098 | prologue, e.g. `%o0' on a sparc. The addition must preserve the | |
17099 | values of all other incoming arguments. | |
17167fd8 MM |
17100 | |
17101 | After the addition, emit code to jump to FUNCTION, which is a | |
a4f6c312 SS |
17102 | `FUNCTION_DECL'. This is a direct pure jump, not a call, and does |
17103 | not touch the return address. Hence returning from FUNCTION will | |
17104 | return to whoever called the current `thunk'. | |
17167fd8 | 17105 | |
a4f6c312 SS |
17106 | The effect must be as if FUNCTION had been called directly with the |
17107 | adjusted first argument. This macro is responsible for emitting | |
17108 | all of the code for a thunk function; output_function_prologue() | |
17109 | and output_function_epilogue() are not invoked. | |
17167fd8 | 17110 | |
a4f6c312 SS |
17111 | The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already |
17112 | been extracted from it.) It might possibly be useful on some | |
17113 | targets, but probably not. | |
17167fd8 | 17114 | |
a4f6c312 SS |
17115 | If you do not define this macro, the target-independent code in the |
17116 | C++ frontend will generate a less efficient heavyweight thunk that | |
17117 | calls FUNCTION instead of jumping to it. The generic approach does | |
17118 | not support varargs. */ | |

18888 | and skews the ready list one way or the other to increase the likelihood | |
18889 | that a desired instruction is issued at the proper time. | |
18890 | ||
18891 | A couple of things are done. First, we maintain a "load_store_pendulum" | |
18892 | to track the current state of load/store issue. | |
18893 | ||
18894 | - If the pendulum is at zero, then no loads or stores have been | |
18895 | issued in the current cycle so we do nothing. | |
18896 | ||
18897 | - If the pendulum is 1, then a single load has been issued in this | |
18898 | cycle and we attempt to locate another load in the ready list to | |
18899 | issue with it. | |
18900 | ||
2f8e468b | 18901 | - If the pendulum is -2, then two stores have already been |
44cd321e PS |
18902 | issued in this cycle, so we increase the priority of the first load |
18903 | in the ready list to increase it's likelihood of being chosen first | |
18904 | in the next cycle. | |
18905 | ||
18906 | - If the pendulum is -1, then a single store has been issued in this | |
18907 | cycle and we attempt to locate another store in the ready list to | |
18908 | issue with it, preferring a store to an adjacent memory location to | |
18909 | facilitate store pairing in the store queue. | |
18910 | ||
18911 | - If the pendulum is 2, then two loads have already been | |
18912 | issued in this cycle, so we increase the priority of the first store | |
18913 | in the ready list to increase it's likelihood of being chosen first | |
18914 | in the next cycle. | |
18915 | ||
18916 | - If the pendulum < -2 or > 2, then do nothing. | |
18917 | ||
18918 | Note: This code covers the most common scenarios. There exist non | |
18919 | load/store instructions which make use of the LSU and which | |
18920 | would need to be accounted for to strictly model the behavior | |
18921 | of the machine. Those instructions are currently unaccounted | |
18922 | for to help minimize compile time overhead of this code. | |

19424 | estimated processor grouping on the compiler (as opposed to the function | |
19425 | 'pad_goups' which tries to force the scheduler's grouping on the processor). | |
19426 | ||

19429 | dispatcher. It marks these group boundaries to reflect the estimated | |
19430 | processor grouping, overriding the grouping that the scheduler had marked. | |
19431 | Depending on the value of the flag '-minsert-sched-nops' this function can | |
19432 | force certain insns into separate groups or force a certain distance between | |
19433 | them by inserting nops, for example, if there exists a "costly dependence" | |
19434 | between the insns. | |

cbe26ab8 DN |

19439 | 4 cases applies: | |
19440 | - no more vacant issue slots remain in the current dispatch group. | |
19441 | - only the last issue slot, which is the branch slot, is vacant, but the next | |
19442 | insn is not a branch. | |
19443 | - only the last 2 or less issue slots, including the branch slot, are vacant, | |
19444 | which means that a cracked insn (which occupies two issue slots) can't be | |
19445 | issued in this group. | |
