The symbols _init and _fini are - magic and cause the linker to emit DT_INIT and DT_FINI. - - This differs from what would be generated for ordinary 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. */ - -#include <libc-symbols.h> -#include <sysdep.h> - -#ifndef PREINIT_FUNCTION -# define PREINIT_FUNCTION __gmon_start__ -#endif - -#ifndef PREINIT_FUNCTION_WEAK -# define PREINIT_FUNCTION_WEAK 1 -#endif - -#if PREINIT_FUNCTION_WEAK - weak_extern (PREINIT_FUNCTION) -#else - .hidden PREINIT_FUNCTION -#endif - - .section .init, "ax", @progbits - .globl _init - .type _init, @function - .usepv _init, std -_init: - ldgp $29, 0($27) - subq $30, 16, $30 -#if PREINIT_FUNCTION_WEAK - lda $27, PREINIT_FUNCTION -#endif - stq $26, 0($30) - stq $29, 8($30) -#if PREINIT_FUNCTION_WEAK - beq $27, 1f - jsr $26, ($27), PREINIT_FUNCTION - ldq $29, 8($30) -1: -#else - bsr $26, PREINIT_FUNCTION !samegp -#endif - .p2align 3 - - .section .fini, "ax", @progbits - .globl _fini - .type _fini,@function - .usepv _fini,std -_fini: - ldgp $29, 0($27) - subq $30, 16, $30 - stq $26, 0($30) - stq $29, 8($30) - .p2align 3 |
