This differs from what would be generated by the generic code in that we save and restore the GP within the function. In order for linker relaxation to work, the value in the GP register on exit from a function must be valid for the function entry point. Normally, a function is contained within one object file and this is not an issue, provided that the function reloads the gp after making any function calls. However, _init and _fini are constructed from pieces of many object files, all of which may have different GP values. So we must reload the GP value from crti.o in crtn.o. */ __asm__ (" \n\ #include \"defs.h\" \n\ \n\ /*@HEADER_ENDS*/ \n\ \n\ /*@_init_PROLOG_BEGINS*/ \n\ .section .init, \"ax\", @progbits \n\ .globl _init \n\ .type _init,@function \n\ .usepv _init,std \n\ _init: \n\ ldgp $29, 0($27) \n\ subq $30, 16, $30 \n\ stq $26, 0($30) \n\ stq $29, 8($30) \n\ bsr $26, __pthread_initialize_minimal_internal !samegp \n\ .align 3 \n\ /*@_init_PROLOG_ENDS*/ \n\ \n\ /*@_init_EPILOG_BEGINS*/ \n\ .section .init, \"ax\", @progbits \n\ ldq $26, 0($30) \n\ ldq $29, 8($30) \n\ addq $30, 16, $30 \n\ ret \n\ /*@_init_EPILOG_ENDS*/ \n\ \n\ /*@_fini_PROLOG_BEGINS*/ \n\ .section .fini, \"ax\", @progbits \n\ .globl _fini \n\ .type _fini,@function \n\ .usepv _fini,std \n\ _fini: \n\ ldgp $29, 0($27) \n\ subq $30, 16, $30 \n\ stq $26, 0($30) \n\ stq $29, 8($30) \n\ .align 3 \n\ /*@_fini_PROLOG_ENDS*/ \n\ \n\ /*@_fini_EPILOG_BEGINS*/ \n\ .section .fini, \"ax\", @progbits \n\ ldq $26, 0($30) \n\ ldq $29, 8($30) \n\ addq $30, 16, $30 \n\ ret \n\ /*@_fini_EPILOG_ENDS*/ \n\ \n\ /*@TRAILER_BEGINS*/ \n\ ");
