The RELOCATE_SECTION function is called by the new ELF backend linker
|
2686 |
|
|
to handle the relocations for a section.
|
2687 |
|
|
|
2688 |
|
|
The relocs are always passed as Rela structures; if the section
|
2689 |
|
|
actually uses Rel structures, the r_addend field will always be
|
2690 |
|
|
zero.
|
2691 |
|
|
|
2692 |
|
|
This function is responsible for adjusting the section contents as
|
2693 |
|
|
necessary, and (if using Rela relocs and generating a relocatable
|
2694 |
|
|
output file) adjusting the reloc addend as necessary.
|
2695 |
|
|
|
2696 |
|
|
This function does not have to worry about setting the reloc
|
2697 |
|
|
address or the reloc symbol index.
|
2698 |
|
|
|
2699 |
|
|
LOCAL_SYMS is a pointer to the swapped in local symbols.
|
2700 |
|
|
|
2701 |
|
|
LOCAL_SECTIONS is an array giving the section in the input file
|
2702 |
|
|
corresponding to the st_shndx field of each local symbol.
|
2703 |
|
|
|
2704 |
|
|
The global hash table entry for the global symbols can be found
|
2705 |
|
|
via elf_sym_hashes (input_bfd).
|
2706 |
|
|
|
2707 |
|
|
When generating relocatable output, this function must handle
|
2708 |
|
|
STB_LOCAL/STT_SECTION symbols specially. The output symbol is
|
2709 |
|
|
going to be the section symbol corresponding to the output
|
2710 |
|
|
section, which means that the addend must be adjusted
|
2711 |
|
|
accordingly. */

supposed to be encountered in this case.

6069 |

used by branches.

6072 |

|
|
6073 |

LABEL24, on the other hand, is used by calls. If it turns out that
|
6074 |
|
|
the target of a call is a dynamic symbol, a PLT entry must be
|
6075 |
|
|
created for it, which triggers the creation of a private function
|
6076 |
|
|
descriptor and, unless lazy binding is disabled, a lazy PLT entry.
|
6077 |
|
|
|
6078 |
|
|
GPREL relocations require the referenced symbol to be in the same
|
6079 |
|
|
segment as _gp, but this can only be checked later.
|
6080 |
|
|
|
6081 |
|
|
All GOT, GOTOFF and FUNCDESC relocations require a .got section to
|
6082 |
|
|
exist. LABEL24 might as well, since it may require a PLT entry,
|
6083 |
|
|
that will require a got.
|
6084 |
|
|
|
6085 |
|
|
Non-FUNCDESC GOT relocations require a GOT entry to be created
|
6086 |
|
|
regardless of whether the symbol is dynamic. However, since a
|
6087 |
|
|
global symbol that turns out to not be exported may have the same
|
6088 |
|
|
address of a non-dynamic symbol, we don't assign GOT entries at
|
6089 |
|
|
this point, such that we can share them in this case. A relocation
|
6090 |
|
|
for the GOT entry always has to be created, be it to offset a
|
6091 |
|
|
private symbol by the section load address, be it to get the symbol
|
6092 |
|
|
resolved dynamically.
|
6093 |
|
|
|
6094 |
|
|
FUNCDESC GOT relocations require a GOT entry to be created, and
|
6095 |
|
|
handled as if a FUNCDESC relocation was applied to the GOT entry in
|
6096 |
|
|
an object file.
|
6097 |
|
|
|
6098 |
|
|
FUNCDESC relocations referencing a symbol that turns out to NOT be
|
6099 |
|
|
dynamic cause a private function descriptor to be created. The
|
6100 |
|
|
FUNCDESC relocation then decays to a 32 relocation that points at
|
6101 |
|
|
the private descriptor. If the symbol is dynamic, the FUNCDESC
|
6102 |
|
|
relocation is propagated to the linker output, such that the
|
6103 |
|
|
dynamic linker creates the canonical descriptor, pointing to the
|
6104 |
|
|
dynamically-resolved definition of the function.
|
6105 |
|
|
|
6106 |
|
|
Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
|
6107 |
|
|
symbols that are assigned to the same segment as the GOT, but we
|
6108 |
|
|
can only check this later, after we know the complete set of
|
6109 |
|
|
symbols defined and/or exported.
|
6110 |
|
|
|
6111 |
|
|
FUNCDESC GOTOFF relocations require a function descriptor to be
|
6112 |
|
|
created and, unless lazy binding is disabled or the symbol is not
|
6113 |
|
|
dynamic, a lazy PLT entry. Since we can't tell at this point
|
6114 |
|
|
whether a symbol is going to be dynamic, we have to decide later
|
6115 |
|
|
whether to create a lazy PLT entry or bind the descriptor directly
|
6116 |
|
|
to the private function.
|
6117 |
|
|
|
6118 |
|
|
FUNCDESC_VALUE relocations are not supposed to be present in object
|
6119 |
|
|
files, but they may very well be simply propagated to the linker
|
6120 |
|
|
output, since they have no side effect.
|
6121 |
|
|
|
6122 |
|
|
|
6123 |
|
|
A function descriptor always requires a FUNCDESC_VALUE relocation.
|
6124 |
|
|
Whether it's in .plt.rel or not depends on whether lazy binding is
|
6125 |
|
|
enabled and on whether the referenced symbol is dynamic.
|
6126 |
|
|
|
6127 |
|
|
The existence of a lazy PLT requires the resolverStub lazy PLT
|
6128 |
|
|
entry to be present.
|
6129 |
|
|
|
6130 |
|
|
|
6131 |
|
|
As for assignment of GOT, PLT and lazy PLT entries, and private
|
6132 |
|
|
descriptors, we might do them all sequentially, but we can do
|
6133 |
|
|
better than that. For example, we can place GOT entries and
|
6134 |
|
|
private function descriptors referenced using 12-bit operands
|
6135 |
|
|
closer to the PIC register value, such that these relocations don't
|
6136 |
|
|
overflow. Those that are only referenced with LO16 relocations
|
6137 |
|
|
could come next, but we may as well place PLT-required function
|
6138 |
|
|
descriptors in the 12-bit range to make them shorter. Symbols
|
6139 |
|
|
referenced with LO16/HI16 may come next, but we may place
|
6140 |
|
|
additional function descriptors in the 16-bit range if we can
|
6141 |
|
|
reliably tell that we've already placed entries that are ever
|
6142 |
|
|
referenced with only LO16. PLT entries are therefore generated as
|
6143 |
|
|
small as possible, while not introducing relocation overflows in
|
6144 |
|
|
GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
|
6145 |
|
|
generated before or after PLT entries, but not intermingled with
|
6146 |
|
|
them, such that we can have more lazy PLT entries in range for a
|
6147 |
|
|
branch to the resolverStub. The resolverStub should be emitted at
|
6148 |
|
|
the most distant location from the first lazy PLT entry such that
|
6149 |
|
|
it's still in range for a branch, or closer, if there isn't a need
|
6150 |
|
|
for so many lazy PLT entries. Additional lazy PLT entries may be
|
6151 |
|
|
emitted after the resolverStub, as long as branches are still in
|
6152 |
|
|
range. If the branch goes out of range, longer lazy PLT entries
|
6153 |
|
|
are emitted.
|
6154 |
|
|
|
6155 |
|
|
We could further optimize PLT and lazy PLT entries by giving them
|
6156 |
|
|
priority in assignment to closer-to-gr17 locations depending on the
|
6157 |
|
|
number of occurrences of references to them (assuming a function
|
6158 |
|
|
that's called more often is more important for performance, so its
|
6159 |
|
|
PLT entry should be faster), or taking hints from the compiler.
