11966 | given. (But note below and in sysv4.h that we require only 8 and | |
11967 | may round up the size of our stack frame anyways. The historical | |
11968 | reason is early versions of powerpc-linux which didn't properly | |
11969 | align the stack at program startup. A happy side-effect is that | |
11970 | -mno-eabi libraries can be used with -meabi programs.) | |

50d440bc | 11972 | The EABI configuration defaults to the V.4 layout. However, |

11973 | the stack alignment requirements may differ. If -mno-eabi is not |
11974 | given, the required stack alignment is 8 bytes; if -mno-eabi is | |

14663 | /* A C compound statement that outputs the assembler code for a thunk |
14664 | function, used to implement C++ virtual function calls with | |
14665 | multiple inheritance. The thunk acts as a wrapper around a virtual | |
14666 | function, adjusting the implicit object parameter before handing | |
14667 | control off to the real function. | |
14668 | ||
14669 | First, emit code to add the integer DELTA to the location that | |
14670 | contains the incoming first argument. Assume that this argument | |
14671 | contains a pointer, and is the one used to pass the `this' pointer | |
14672 | in C++. This is the incoming argument *before* the function | |
14673 | prologue, e.g. `%o0' on a sparc. The addition must preserve the | |
14674 | values of all other incoming arguments. | |
17167fd8 MM |
14675 | |
14676 | After the addition, emit code to jump to FUNCTION, which is a | |
a4f6c312 SS |
14677 | `FUNCTION_DECL'. This is a direct pure jump, not a call, and does |
14678 | not touch the return address. Hence returning from FUNCTION will | |
14679 | return to whoever called the current `thunk'. | |
17167fd8 | 14680 | |
a4f6c312 SS |
14681 | The effect must be as if FUNCTION had been called directly with the |
14682 | adjusted first argument. This macro is responsible for emitting | |
14683 | all of the code for a thunk function; output_function_prologue() | |
14684 | and output_function_epilogue() are not invoked. | |
17167fd8 | 14685 | |
a4f6c312 SS |
14686 | The THUNK_FNDECL is redundant. (DELTA and FUNCTION have already |
14687 | been extracted from it.) It might possibly be useful on some | |
14688 | targets, but probably not. | |
17167fd8 | 14689 | |
a4f6c312 SS |
14690 | If you do not define this macro, the target-independent code in the |
14691 | C++ frontend will generate a less efficient heavyweight thunk that | |
14692 | calls FUNCTION instead of jumping to it. The generic approach does | |
14693 | not support varargs. */ | |

16228 | estimated processor grouping on the compiler (as opposed to the function | |
16229 | 'pad_goups' which tries to force the scheduler's grouping on the processor). | |
16230 | ||

16232 | examines the (estimated) dispatch groups that will be formed by the processor | |
16233 | dispatcher. It marks these group boundaries to reflect the estimated | |
16234 | processor grouping, overriding the grouping that the scheduler had marked. | |
16235 | Depending on the value of the flag '-minsert-sched-nops' this function can | |
16236 | force certain insns into separate groups or force a certain distance between | |
16237 | them by inserting nops, for example, if there exists a "costly dependence" | |
16238 | between the insns. | |

cbe26ab8 DN |

16243 | 4 cases applies: | |
16244 | - no more vacant issue slots remain in the current dispatch group. | |
16245 | - only the last issue slot, which is the branch slot, is vacant, but the next | |
16246 | insn is not a branch. | |
16247 | - only the last 2 or less issue slots, including the branch slot, are vacant, | |
16248 | which means that a cracked insn (which occupies two issue slots) can't be | |
16249 | issued in this group. | |
