A common routine <<bfd_perform_relocation>> acts upon the canonical form to do the fixup. Relocations are maintained on a per section basis, while symbols are maintained on a per BFD basis. All that a back end has to do to fit the BFD interface is to create a <<struct reloc_cache_entry>> for each relocation in a particular section, and fill in the right bits of the structures. @menu @* typedef arelent:: @* howto manager:: @end menu */ /* DO compile in the reloc_code name table from libbfd.h. */ #define _BFD_MAKE_TABLE_bfd_reloc_code_real #include "sysdep.h" #include "bfd.h" #include "bfdlink.h" #include "libbfd.h" /* DOCDD INODE typedef arelent, howto manager, Relocations, Relocations SUBSECTION typedef arelent This is the structure of a relocation entry: CODE_FRAGMENT . .typedef enum bfd_reloc_status .{ . {* No errors detected. *} . bfd_reloc_ok, . . {* The relocation was performed, but there was an overflow. *} . bfd_reloc_overflow, . . {* The address to relocate was not within the section supplied. *} . bfd_reloc_outofrange, . . {* Used by special functions. *} . bfd_reloc_continue, . . {* Unsupported relocation size requested. *} . bfd_reloc_notsupported, . . {* Unused. *} . bfd_reloc_other, . . {* The symbol to relocate against was undefined. *} . bfd_reloc_undefined, . . {* The relocation was performed, but may not be ok - presently . generated only when linking i960 coff files with i960 b.out . symbols.

It is the pointer into the table returned by the back end's <<canonicalize_symtab>> action. @xref{Symbols}. The symbol is referenced through a pointer to a pointer so that tools like the linker can fix up all the symbols of the same name by modifying only one pointer. The relocation routine looks in the symbol and uses the base of the section the symbol is attached to and the value of the symbol as the initial relocation offset. If the symbol pointer is zero, then the section provided is looked up. o <<address>> The <<address>> field gives the offset in bytes from the base of the section data which owns the relocation record to the first byte of relocatable information. The actual data relocated will be relative to this point; for example, a relocation type which modifies the bottom two bytes of a four byte word would not touch the first byte pointed to in a big endian world. o <<addend>> The <<addend>> is a value provided by the back end to be added (!) to the relocation offset. Its interpretation is dependent upon the howto. For example, on the 68k the code: | char foo[]; | main() | { | return foo[0x12345678]; | } Could be compiled into: | linkw fp,#-4 | moveb @@#12345678,d0 | extbl d0 | unlk fp | rts This could create a reloc pointing to <<foo>>, but leave the offset in the data, something like: |RELOCATION RECORDS FOR [.text]: |offset type value |00000006 32 _foo | |00000000 4e56 fffc ; linkw fp,#-4 |00000004 1039 1234 5678 ; moveb @@#12345678,d0 |0000000a 49c0 ; extbl d0 |0000000c 4e5e ; unlk fp |0000000e 4e75 ; rts Using coff and an 88k, some instructions don't have enough space in them to represent the full address range, and pointers have to be loaded in two parts. So you'd get something like: | or.u r13,r0,hi16(_foo+0x12345678) | ld.b r2,r13,lo16(_foo+0x12345678) | jmp r1 This should create two relocs, both pointing to <<_foo>>, and with 0x12340000 in their addend field. The data would consist of: |RELOCATION RECORDS FOR [.text]: |offset type value |00000002 HVRT16 _foo+0x12340000 |00000006 LVRT16 _foo+0x12340000 | |00000000 5da05678 ; or.u r13,r0,0x5678 |00000004 1c4d5678 ; ld.b r2,r13,0x5678 |00000008 f400c001 ; jmp r1 The relocation routine digs out the value from the data, adds it to the addend to get the original offset, and then adds the value of <<_foo>>. Note that all 32 bits have to be kept around somewhere, to cope with carry from bit 15 to bit 16. One further example is the sparc and the a.out format. The sparc has a similar problem to the 88k, in that some instructions don't have room for an entire offset, but on the sparc the parts are created in odd sized lumps. The designers of the a.out format chose to not use the data within the section for storing part of the offset; all the offset is kept within the reloc. Anything in the data should be ignored. | save %sp,-112,%sp | sethi %hi(_foo+0x12345678),%g2 | ldsb [%g2+%lo(_foo+0x12345678)],%i0 | ret | restore Both relocs contain a pointer to <<foo>>, and the offsets contain junk. |RELOCATION RECORDS FOR [.text]: |offset type value |00000004 HI22 _foo+0x12345678 |00000008 LO10 _foo+0x12345678 | |00000000 9de3bf90 ; save %sp,-112,%sp |00000004 05000000 ; sethi %hi(_foo+0),%g2 |00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 |0000000c 81c7e008 ; ret |00000010 81e80000 ; restore o <<howto>> The <<howto>> field can be imagined as a relocation instruction. It is a pointer to a structure which contains information on what to do with all of the other information in the reloc record and data section. A back end would normally have a relocation instruction set and turn relocations into pointers to the correct structure on input - but it would be possible to create each howto field on demand. */ /* SUBSUBSECTION <<enum complain_overflow>> Indicates what sort of overflow checking should be done when performing a relocation.

Removing the line below this comment fixes that problem; see PR 2953. However, Ian wrote the following, regarding removing the line below, which explains why it is still enabled: --djm If you put a patch like that into BFD you need to check all the COFF linkers. I am fairly certain that patch will break coff-i386 (e.g., SCO); see coff_i386_reloc in coff-i386.c where I worked around the problem in a different way. There may very well be a reason that the code works as it does. Hmmm. The first obvious point is that bfd_perform_relocation should not have any tests that depend upon the flavour. It's seem like entirely the wrong place for such a thing. The second obvious point is that the current code ignores the reloc addend when producing relocatable output for COFF. That's peculiar. In fact, I really have no idea what the point of the line you want to remove is. A typical COFF reloc subtracts the old value of the symbol and adds in the new value to the location in the object file (if it's a pc relative reloc it adds the difference between the symbol value and the location). When relocating we need to preserve that property. BFD handles this by setting the addend to the negative of the old value of the symbol. Unfortunately it handles common symbols in a non-standard way (it doesn't subtract the old value) but that's a different story (we can't change it without losing backward compatibility with old object files) (coff-i386 does subtract the old value, to be compatible with existing coff-i386 targets, like SCO). So everything works fine when not producing relocatable output. When we are producing relocatable output, logically we should do exactly what we do when not producing relocatable output. Therefore, your patch is correct. In fact, it should probably always just set reloc_entry->addend to 0 for all cases, since it is, in fact, going to add the value into the object file. This won't hurt the COFF code, which doesn't use the addend; I'm not sure what it will do to other formats (the thing to check for would be whether any formats both use the addend and set partial_inplace). When I wanted to make coff-i386 produce relocatable output, I ran into the problem that you are running into: I wanted to remove that line. Rather than risk it, I made the coff-i386 relocs use a special function; it's coff_i386_reloc in coff-i386.c. The function specifically adds the addend field into the object file, knowing that bfd_perform_relocation is not going to. If you remove that line, then coff-i386.c will wind up adding the addend field in twice. It's trivial to fix; it just needs to be done. The problem with removing the line is just that it may break some working code. With BFD it's hard to be sure of anything. The right way to deal with this is simply to build and test at least all the supported COFF targets. It should be straightforward if time and disk space consuming. For each target: 1) build the linker 2) generate some executable, and link it using -r (I would probably use paranoia.o and link against newlib/libc.a, which for all the supported targets would be available in /usr/cygnus/progressive/H-host/target/lib/libc.a). 3) make the change to reloc.c 4) rebuild the linker 5) repeat step 2 6) if the resulting object files are the same, you have at least made it no worse 7) if they are different you have to figure out which version is right */ relocation -= reloc_entry->addend; reloc_entry->addend = 0; } else { reloc_entry->addend = relocation; } } } else { reloc_entry->addend = 0; } /* FIXME: This overflow checking is incomplete, because the value might have overflowed before we get here.

Removing the line below this comment fixes that problem; see PR 2953. However, Ian wrote the following, regarding removing the line below, which explains why it is still enabled: --djm If you put a patch like that into BFD you need to check all the COFF linkers. I am fairly certain that patch will break coff-i386 (e.g., SCO); see coff_i386_reloc in coff-i386.c where I worked around the problem in a different way. There may very well be a reason that the code works as it does. Hmmm. The first obvious point is that bfd_install_relocation should not have any tests that depend upon the flavour. It's seem like entirely the wrong place for such a thing. The second obvious point is that the current code ignores the reloc addend when producing relocatable output for COFF. That's peculiar. In fact, I really have no idea what the point of the line you want to remove is. A typical COFF reloc subtracts the old value of the symbol and adds in the new value to the location in the object file (if it's a pc relative reloc it adds the difference between the symbol value and the location). When relocating we need to preserve that property. BFD handles this by setting the addend to the negative of the old value of the symbol. Unfortunately it handles common symbols in a non-standard way (it doesn't subtract the old value) but that's a different story (we can't change it without losing backward compatibility with old object files) (coff-i386 does subtract the old value, to be compatible with existing coff-i386 targets, like SCO). So everything works fine when not producing relocatable output. When we are producing relocatable output, logically we should do exactly what we do when not producing relocatable output. Therefore, your patch is correct. In fact, it should probably always just set reloc_entry->addend to 0 for all cases, since it is, in fact, going to add the value into the object file. This won't hurt the COFF code, which doesn't use the addend; I'm not sure what it will do to other formats (the thing to check for would be whether any formats both use the addend and set partial_inplace). When I wanted to make coff-i386 produce relocatable output, I ran into the problem that you are running into: I wanted to remove that line. Rather than risk it, I made the coff-i386 relocs use a special function; it's coff_i386_reloc in coff-i386.c. The function specifically adds the addend field into the object file, knowing that bfd_install_relocation is not going to. If you remove that line, then coff-i386.c will wind up adding the addend field in twice. It's trivial to fix; it just needs to be done. The problem with removing the line is just that it may break some working code. With BFD it's hard to be sure of anything. The right way to deal with this is simply to build and test at least all the supported COFF targets. It should be straightforward if time and disk space consuming. For each target: 1) build the linker 2) generate some executable, and link it using -r (I would probably use paranoia.o and link against newlib/libc.a, which for all the supported targets would be available in /usr/cygnus/progressive/H-host/target/lib/libc.a). 3) make the change to reloc.c 4) rebuild the linker 5) repeat step 2 6) if the resulting object files are the same, you have at least made it no worse 7) if they are different you have to figure out which version is right. */ relocation -= reloc_entry->addend; /* FIXME: There should be no target specific code here... */ if (strcmp (abfd->xvec->name, "coff-z8k") != 0) reloc_entry->addend = 0; } else { reloc_entry->addend = relocation; } } /* FIXME: This overflow checking is incomplete, because the value might have overflowed before we get here.

ENUM BFD_RELOC_ALPHA_GPDISP_HI16 ENUMDOC Alpha ECOFF and ELF relocations. Some of these treat the symbol or "addend" in some special way. For GPDISP_HI16 ("gpdisp") relocations, the symbol is ignored when writing; when reading, it will be the absolute section symbol. The addend is the displacement in bytes of the "lda" instruction from the "ldah" instruction (which is at the address of this reloc). ENUM BFD_RELOC_ALPHA_GPDISP_LO16 ENUMDOC For GPDISP_LO16 ("ignore") relocations, the symbol is handled as with GPDISP_HI16 relocs. The addend is ignored when writing the relocations out, and is filled in with the file's GP value on reading, for convenience. ENUM BFD_RELOC_ALPHA_GPDISP ENUMDOC The ELF GPDISP relocation is exactly the same as the GPDISP_HI16 relocation except that there is no accompanying GPDISP_LO16 relocation. ENUM BFD_RELOC_ALPHA_LITERAL ENUMX BFD_RELOC_ALPHA_ELF_LITERAL ENUMX BFD_RELOC_ALPHA_LITUSE ENUMDOC The Alpha LITERAL/LITUSE relocs are produced by a symbol reference; the assembler turns it into a LDQ instruction to load the address of the symbol, and then fills in a register in the real instruction. The LITERAL reloc, at the LDQ instruction, refers to the .lita section symbol. The addend is ignored when writing, but is filled in with the file's GP value on reading, for convenience, as with the GPDISP_LO16 reloc. The ELF_LITERAL reloc is somewhere between 16_GOTOFF and GPDISP_LO16. It should refer to the symbol to be referenced, as with 16_GOTOFF, but it generates output not based on the position within the .got section, but relative to the GP value chosen for the file during the final link stage. The LITUSE reloc, on the instruction using the loaded address, gives information to the linker that it might be able to use to optimize away some literal section references. The symbol is ignored (read as the absolute section symbol), and the "addend" indicates the type of instruction using the register: 1 - "memory" fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target of branch) ENUM BFD_RELOC_ALPHA_HINT ENUMDOC The HINT relocation indicates a value that should be filled into the "hint" field of a jmp/jsr/ret instruction, for possible branch- prediction logic which may be provided on some processors. ENUM BFD_RELOC_ALPHA_LINKAGE ENUMDOC The LINKAGE relocation outputs a linkage pair in the object file, which is filled by the linker. ENUM BFD_RELOC_ALPHA_CODEADDR ENUMDOC The CODEADDR relocation outputs a STO_CA in the object file, which is filled by the linker. ENUM BFD_RELOC_ALPHA_GPREL_HI16 ENUMX BFD_RELOC_ALPHA_GPREL_LO16 ENUMDOC The GPREL_HI/LO relocations together form a 32-bit offset from the GP register. ENUM BFD_RELOC_ALPHA_BRSGP ENUMDOC Like BFD_RELOC_23_PCREL_S2, except that the source and target must share a common GP, and the target address is adjusted for STO_ALPHA_STD_GPLOAD.

When the --gc-sections option is given, the linker will zero out the entries that are not used, so that the code for those functions need not be included in the output. VTABLE_INHERIT is a zero-space relocation used to describe to the linker the inheritance tree of a C++ virtual function table. The relocation's symbol should be the parent class' vtable, and the relocation should be located at the child vtable. VTABLE_ENTRY is a zero-space relocation that describes the use of a virtual function table entry. The reloc's symbol should refer to the table of the class mentioned in the code. Off of that base, an offset describes the entry that is being used. For Rela hosts, this offset is stored in the reloc's addend. For Rel hosts, we are forced to put this offset in the reloc's section offset.
