51532845 AO |
5911 | |
5912 | Besides handling virtual table relocs for gc, we have to deal with | |
5913 | all sorts of PIC-related relocations. We describe below the | |
5914 | general plan on how to handle such relocations, even though we only | |
5915 | collect information at this point, storing them in hash tables for | |
5916 | perusal of later passes. | |
5917 | ||
5918 | 32 relocations are propagated to the linker output when creating | |
5919 | position-independent output. LO16 and HI16 relocations are not | |
5920 | supposed to be encountered in this case. | |
5921 | ||
5922 | LABEL16 should always be resolvable by the linker, since it's only | |
5923 | used by branches. | |
5924 | ||
5925 | LABEL24, on the other hand, is used by calls. If it turns out that | |
5926 | the target of a call is a dynamic symbol, a PLT entry must be | |
5927 | created for it, which triggers the creation of a private function | |
5928 | descriptor and, unless lazy binding is disabled, a lazy PLT entry. | |
5929 | ||
5930 | GPREL relocations require the referenced symbol to be in the same | |
5931 | segment as _gp, but this can only be checked later. | |
5932 | ||
5933 | All GOT, GOTOFF and FUNCDESC relocations require a .got section to | |
5934 | exist. LABEL24 might as well, since it may require a PLT entry, | |
5935 | that will require a got. | |
5936 | ||
5937 | Non-FUNCDESC GOT relocations require a GOT entry to be created | |
5938 | regardless of whether the symbol is dynamic. However, since a | |
5939 | global symbol that turns out to not be exported may have the same | |
5940 | address of a non-dynamic symbol, we don't assign GOT entries at | |
5941 | this point, such that we can share them in this case. A relocation | |
5942 | for the GOT entry always has to be created, be it to offset a | |
5943 | private symbol by the section load address, be it to get the symbol | |
5944 | resolved dynamically. | |
5945 | ||
5946 | FUNCDESC GOT relocations require a GOT entry to be created, and | |
5947 | handled as if a FUNCDESC relocation was applied to the GOT entry in | |
5948 | an object file. | |
5949 | ||
5950 | FUNCDESC relocations referencing a symbol that turns out to NOT be | |
5951 | dynamic cause a private function descriptor to be created. The | |
5952 | FUNCDESC relocation then decays to a 32 relocation that points at | |
5953 | the private descriptor. If the symbol is dynamic, the FUNCDESC | |
5954 | relocation is propagated to the linker output, such that the | |
5955 | dynamic linker creates the canonical descriptor, pointing to the | |
5956 | dynamically-resolved definition of the function. | |
5957 | ||
5958 | Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic | |
5959 | symbols that are assigned to the same segment as the GOT, but we | |
5960 | can only check this later, after we know the complete set of | |
5961 | symbols defined and/or exported. | |
5962 | ||
5963 | FUNCDESC GOTOFF relocations require a function descriptor to be | |
5964 | created and, unless lazy binding is disabled or the symbol is not | |
5965 | dynamic, a lazy PLT entry. Since we can't tell at this point | |
5966 | whether a symbol is going to be dynamic, we have to decide later | |
5967 | whether to create a lazy PLT entry or bind the descriptor directly | |
5968 | to the private function. | |
5969 | ||
5970 | FUNCDESC_VALUE relocations are not supposed to be present in object | |
5971 | files, but they may very well be simply propagated to the linker | |
5972 | output, since they have no side effect. | |
5973 | ||
5974 | ||
5975 | A function descriptor always requires a FUNCDESC_VALUE relocation. | |
5976 | Whether it's in .plt.rel or not depends on whether lazy binding is | |
5977 | enabled and on whether the referenced symbol is dynamic. | |
5978 | ||
5979 | The existence of a lazy PLT requires the resolverStub lazy PLT | |
5980 | entry to be present. | |
5981 | ||
5982 | ||
5983 | As for assignment of GOT, PLT and lazy PLT entries, and private | |
5984 | descriptors, we might do them all sequentially, but we can do | |
5985 | better than that. For example, we can place GOT entries and | |
5986 | private function descriptors referenced using 12-bit operands | |
5987 | closer to the PIC register value, such that these relocations don't | |
5988 | overflow. Those that are only referenced with LO16 relocations | |
5989 | could come next, but we may as well place PLT-required function | |
5990 | descriptors in the 12-bit range to make them shorter. Symbols | |
5991 | referenced with LO16/HI16 may come next, but we may place | |
5992 | additional function descriptors in the 16-bit range if we can | |
5993 | reliably tell that we've already placed entries that are ever | |
5994 | referenced with only LO16. PLT entries are therefore generated as | |
5995 | small as possible, while not introducing relocation overflows in | |
5996 | GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be | |
5997 | generated before or after PLT entries, but not intermingled with | |
5998 | them, such that we can have more lazy PLT entries in range for a | |
5999 | branch to the resolverStub. The resolverStub should be emitted at | |
6000 | the most distant location from the first lazy PLT entry such that | |
6001 | it's still in range for a branch, or closer, if there isn't a need | |
6002 | for so many lazy PLT entries. Additional lazy PLT entries may be | |
6003 | emitted after the resolverStub, as long as branches are still in | |
6004 | range. If the branch goes out of range, longer lazy PLT entries | |
6005 | are emitted. | |
6006 | ||
6007 | We could further optimize PLT and lazy PLT entries by giving them | |
6008 | priority in assignment to closer-to-gr17 locations depending on the | |
6009 | number of occurrences of references to them (assuming a function | |
6010 | that's called more often is more important for performance, so its | |
6011 | PLT entry should be faster), or taking hints from the compiler. | |
6012 | Given infinite time and money... :-) */ | |
