Lu * bfd-in.h (bfd_elf32_ia64_after_parse): New prototype. (bfd_elf64_ia64_after_parse): Likewise. * bfd-in2.h: Regenerated. * elfxx-ia64.c (oor_ip): New. (oor_branch_size): Likewise. (bfd_elfNN_ia64_after_parse): Likewise. (elfNN_ia64_relax_section): Use oor_ip if oor_branch_size equals sizeof (oor_ip). ld/ 2003-10-10 H.J. Lu * Makefile.am (eelf64_ia64.c): Also depend on $(srcdir)/emultempl/ia64elf.em. * Makefile.in: Regenerated. * emulparams/elf64_ia64.sh (EXTRA_EM_FILE): Set to ia64elf. * emultempl/ia64elf.em: New. --- bfd/elfxx-ia64.c | 46 +++++++++++++++++++++++++++++++++++++++------- 1 file changed, 39 insertions(+), 7 deletions(-) (limited to 'bfd/elfxx-ia64.c') diff --git a/bfd/elfxx-ia64.c b/bfd/elfxx-ia64.c index 15f7c0a..ed626bf 100644 --- a/bfd/elfxx-ia64.c +++ b/bfd/elfxx-ia64.c @@ -656,6 +656,28 @@ static const bfd_byte oor_brl[16] = 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* brl.sptk.few tgt;; */ 0x00, 0x00, 0x00, 0xc0 }; + +static const bfd_byte oor_ip[48] = +{ + 0x04, 0x00, 0x00, 0x00, 0x01, 0x00, /* [MLX] nop.m 0 */ + 0x00, 0x00, 0x00, 0x00, 0x00, 0xe0, /* movl r15=0 */ + 0x01, 0x00, 0x00, 0x60, + 0x03, 0x00, 0x00, 0x00, 0x01, 0x00, /* [MII] nop.m 0 */ + 0x00, 0x01, 0x00, 0x60, 0x00, 0x00, /* mov r16=ip;; */ + 0xf2, 0x80, 0x00, 0x80, /* add r16=r15,r16;; */ + 0x11, 0x00, 0x00, 0x00, 0x01, 0x00, /* [MIB] nop.m 0 */ + 0x60, 0x80, 0x04, 0x80, 0x03, 0x00, /* mov b6=r16 */ + 0x60, 0x00, 0x80, 0x00 /* br b6;; */ +}; + +static size_t oor_branch_size = sizeof (oor_brl); + +void +bfd_elfNN_ia64_after_parse (int itanium) +{ + oor_branch_size = itanium ? sizeof (oor_ip) : sizeof (oor_brl); +} + /* These functions do relaxation for IA-64 ELF. */ @@ -891,9 +913,7 @@ elfNN_ia64_relax_section (abfd, sec, link_info, again) if (tsec == ia64_info->plt_sec) size = sizeof (plt_full_entry); else - { - size = sizeof (oor_brl); - } + size = oor_branch_size; /* Resize the current section to make room for the new branch. */ trampoff = (sec->_cooked_size + 15) & (bfd_vma) -16; @@ -914,10 +934,22 @@ elfNN_ia64_relax_section (abfd, sec, link_info, again) } else { - memcpy (contents + trampoff, oor_brl, size); - irel->r_info = ELFNN_R_INFO (ELFNN_R_SYM (irel->r_info), - R_IA64_PCREL60B); - irel->r_offset = trampoff + 2; + if (size == sizeof (oor_ip)) + { + memcpy (contents + trampoff, oor_ip, size); + irel->r_info = ELFNN_R_INFO (ELFNN_R_SYM (irel->r_info), + R_IA64_PCREL64I); + irel->r_addend -= 16; + irel->r_offset = trampoff + 2; + } + else + { + memcpy (contents + trampoff, oor_brl, size); + irel->r_info = ELFNN_R_INFO (ELFNN_R_SYM (irel->r_info), + R_IA64_PCREL60B); + irel->r_offset = trampoff + 2; + } + } /* Record the fixup so we don't do it again this section. */ -- cgit v1.1
