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\ -"); diff --git a/libpthread/nptl/sysdeps/alpha/jmpbuf-unwind.h b/libpthread/nptl/sysdeps/alpha/jmpbuf-unwind.h deleted file mode 100644 index 5cef8b1cf..000000000 --- a/libpthread/nptl/sysdeps/alpha/jmpbuf-unwind.h +++ /dev/null @@ -1,31 +0,0 @@ -/* Copyright (C) 2003, 2004 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Jakub Jelinek <jakub@redhat.com>, 2003. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
