From a11c78e7ddcbb5b7c6d703334a3e5a5cabf1919d Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 30 Jul 1999 21:42:21 +0000 Subject: [PATCH] Jakub Jelinek * elf64-sparc.c (sparc64_elf_build_plt): Cosmetic change - ABI wants ba,a,pt %xcc instead of %icc. Emit correct .PLT0-(.PLTN+4) initial value into the pointer slots of large PLT entries. (sparc64_elf_plt_ptr_offset): Fix calculation. (sparc64_elf_finish_dynamic_symbol): Negative value of R_SPARC_JMP_SLOT addend should be relative to load address, not .plt section start. (sparc64_elf_size_info): Sparc64 uses 32bit .hash entries. --- bfd/ChangeLog | 11 +++++++++++ bfd/elf64-sparc.c | 23 ++++++++++++++--------- 2 files changed, 25 insertions(+), 9 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index a6ce27659d9..b9951104894 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,14 @@ +1999-07-30 Jakub Jelinek + + * elf64-sparc.c (sparc64_elf_build_plt): Cosmetic change - ABI + wants ba,a,pt %xcc instead of %icc. + Emit correct .PLT0-(.PLTN+4) initial value into the pointer slots + of large PLT entries. + (sparc64_elf_plt_ptr_offset): Fix calculation. + (sparc64_elf_finish_dynamic_symbol): Negative value of R_SPARC_JMP_SLOT + addend should be relative to load address, not .plt section start. + (sparc64_elf_size_info): Sparc64 uses 32bit .hash entries. + 1999-07-30 Jakub Jelinek * elf-bfd.h (struct elf_backend_data): Add diff --git a/bfd/elf64-sparc.c b/bfd/elf64-sparc.c index 107f3714029..733ea5e5c79 100644 --- a/bfd/elf64-sparc.c +++ b/bfd/elf64-sparc.c @@ -875,8 +875,8 @@ sparc64_elf_build_plt (output_bfd, contents, nentries) /* sethi (. - plt0), %g1 */ sethi = 0x03000000 | (i * PLT_ENTRY_SIZE); - /* ba,a,pt %icc, plt1 */ - ba = 0x30480000 | (((contents+PLT_ENTRY_SIZE) - (entry+4)) / 4 & 0x7ffff); + /* ba,a,pt %xcc, plt1 */ + ba = 0x30680000 | (((contents+PLT_ENTRY_SIZE) - (entry+4)) / 4 & 0x7ffff); bfd_put_32 (output_bfd, sethi, entry); bfd_put_32 (output_bfd, ba, entry+4); @@ -913,7 +913,7 @@ sparc64_elf_build_plt (output_bfd, contents, nentries) bfd_put_32 (output_bfd, 0x83c3c001, entry+16); /* jmpl %o7+%g1,%g1 */ bfd_put_32 (output_bfd, 0x9e100005, entry+20); /* mov %g5,%o7 */ - bfd_put_64 (output_bfd, contents - entry+4, ptr); + bfd_put_64 (output_bfd, contents - (entry+4), ptr); } } } @@ -948,11 +948,15 @@ sparc64_elf_plt_ptr_offset (index, max) /* See above for details. */ - block = (index - LARGE_PLT_THRESHOLD) / 160; - ofs = (index - LARGE_PLT_THRESHOLD) % 160; - last = (max - LARGE_PLT_THRESHOLD) % 160; + block = (((index - LARGE_PLT_THRESHOLD) / 160) * 160) + + LARGE_PLT_THRESHOLD; + ofs = index - block; + if (block + 160 > max) + last = (max - LARGE_PLT_THRESHOLD) % 160; + else + last = 160; - return ((LARGE_PLT_THRESHOLD + block*160) * PLT_ENTRY_SIZE + return (block * PLT_ENTRY_SIZE + last * 6*4 + ofs * 8); } @@ -2566,7 +2570,8 @@ sparc64_elf_finish_dynamic_symbol (output_bfd, info, h, sym) { int max = splt->_raw_size / PLT_ENTRY_SIZE; rela.r_offset = sparc64_elf_plt_ptr_offset (h->plt.offset, max); - rela.r_addend = -(sparc64_elf_plt_entry_offset (h->plt.offset) + 4); + rela.r_addend = -(sparc64_elf_plt_entry_offset (h->plt.offset) + 4) + -(splt->output_section->vma + splt->output_offset); } rela.r_offset += (splt->output_section->vma + splt->output_offset); rela.r_info = ELF64_R_INFO (h->dynindx, R_SPARC_JMP_SLOT); @@ -2896,7 +2901,7 @@ const struct elf_size_info sparc64_elf_size_info = sizeof (Elf64_External_Sym), sizeof (Elf64_External_Dyn), sizeof (Elf_External_Note), - 8, /* hash-table entry size */ + 4, /* hash-table entry size */ /* internal relocations per external relocations.
