It generates correct ELF files for all of the input I've given it +so far. I've used this version of libbfd.a to build an hppa/elf +version of gas 1.36 (emits SOM). I've run files as large as 200K +lines of assembly through it. + +2. ELF executables that are created *always* have 3 program header +table entries. This is due to the exec() support we have in the +kernel for ELF executables. It expects *exactly* 3 program header +table entries -- one for text, one for data, and one for bss. +Currently, there's no support for any other types of program header +table entries. diff --git a/bfd/elf32-hppa.c b/bfd/elf32-hppa.c new file mode 100644 index 00000000000..0b0ecbef397 --- /dev/null +++ b/bfd/elf32-hppa.c @@ -0,0 +1,1648 @@ +/* BFD back-end for HP PA-RISC ELF files. + Copyright (C) 1990-1991 Free Software Foundation, Inc. + + Written by + + Center for Software Science + Department of Computer Science + University of Utah + +This file is part of BFD, the Binary File Descriptor library. + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or +(at your option) any later version. + +This program 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.
