A common 30 routine <<bfd_perform_relocation>> acts upon the 31 canonical form to do the fixup. 32 33 Relocations are maintained on a per section basis, 34 while symbols are maintained on a per BFD basis. 35 36 All that a back end has to do to fit the BFD interface is to create 37 a <<struct reloc_cache_entry>> for each relocation 38 in a particular section, and fill in the right bits of the structures. 39 40@menu 41@* typedef arelent:: 42@* howto manager:: 43@end menu 44 45*/ 46 47/* DO compile in the reloc_code name table from libbfd.h. */ 48#define _BFD_MAKE_TABLE_bfd_reloc_code_real 49 50#include "sysdep.h" 51#include "bfd.h" 52#include "bfdlink.h" 53#include "libbfd.h" 54/* 55DOCDD 56INODE 57 typedef arelent, howto manager, Relocations, Relocations 58 59SUBSECTION 60 typedef arelent 61 62 This is the structure of a relocation entry: 63 64CODE_FRAGMENT 65. 66.typedef enum bfd_reloc_status 67.{ 68. {* No errors detected. *} 69. bfd_reloc_ok, 70. 71. {* The relocation was performed, but there was an overflow. *} 72. bfd_reloc_overflow, 73. 74. {* The address to relocate was not within the section supplied. *} 75. bfd_reloc_outofrange, 76. 77. {* Used by special functions. *} 78. bfd_reloc_continue, 79. 80. {* Unsupported relocation size requested. *} 81. bfd_reloc_notsupported, 82. 83. {* Unused. *} 84. bfd_reloc_other, 85. 86. {* The symbol to relocate against was undefined. *} 87. bfd_reloc_undefined, 88. 89. {* The relocation was performed, but may not be ok - presently 90. generated only when linking i960 coff files with i960 b.out 91. symbols.

It is the pointer 126 into the table returned by the back end's 127 <<canonicalize_symtab>> action. @xref{Symbols}. The symbol is 128 referenced through a pointer to a pointer so that tools like 129 the linker can fix up all the symbols of the same name by 130 modifying only one pointer. The relocation routine looks in 131 the symbol and uses the base of the section the symbol is 132 attached to and the value of the symbol as the initial 133 relocation offset. If the symbol pointer is zero, then the 134 section provided is looked up. 135 136 o <<address>> 137 138 The <<address>> field gives the offset in bytes from the base of 139 the section data which owns the relocation record to the first 140 byte of relocatable information. The actual data relocated 141 will be relative to this point; for example, a relocation 142 type which modifies the bottom two bytes of a four byte word 143 would not touch the first byte pointed to in a big endian 144 world. 145 146 o <<addend>> 147 148 The <<addend>> is a value provided by the back end to be added (!) 149 to the relocation offset. Its interpretation is dependent upon 150 the howto. For example, on the 68k the code: 151 152| char foo[]; 153| main() 154| { 155| return foo[0x12345678]; 156| } 157 158 Could be compiled into: 159 160| linkw fp,#-4 161| moveb @@#12345678,d0 162| extbl d0 163| unlk fp 164| rts 165 166 This could create a reloc pointing to <<foo>>, but leave the 167 offset in the data, something like: 168 169|RELOCATION RECORDS FOR [.text]: 170|offset type value 171|00000006 32 _foo 172| 173|00000000 4e56 fffc ; linkw fp,#-4 174|00000004 1039 1234 5678 ; moveb @@#12345678,d0 175|0000000a 49c0 ; extbl d0 176|0000000c 4e5e ; unlk fp 177|0000000e 4e75 ; rts 178 179 Using coff and an 88k, some instructions don't have enough 180 space in them to represent the full address range, and 181 pointers have to be loaded in two parts. So you'd get something like: 182 183| or.u r13,r0,hi16(_foo+0x12345678) 184| ld.b r2,r13,lo16(_foo+0x12345678) 185| jmp r1 186 187 This should create two relocs, both pointing to <<_foo>>, and with 188 0x12340000 in their addend field. The data would consist of: 189 190|RELOCATION RECORDS FOR [.text]: 191|offset type value 192|00000002 HVRT16 _foo+0x12340000 193|00000006 LVRT16 _foo+0x12340000 194| 195|00000000 5da05678 ; or.u r13,r0,0x5678 196|00000004 1c4d5678 ; ld.b r2,r13,0x5678 197|00000008 f400c001 ; jmp r1 198 199 The relocation routine digs out the value from the data, adds 200 it to the addend to get the original offset, and then adds the 201 value of <<_foo>>. Note that all 32 bits have to be kept around 202 somewhere, to cope with carry from bit 15 to bit 16. 203 204 One further example is the sparc and the a.out format. The 205 sparc has a similar problem to the 88k, in that some 206 instructions don't have room for an entire offset, but on the 207 sparc the parts are created in odd sized lumps. The designers of 208 the a.out format chose to not use the data within the section 209 for storing part of the offset; all the offset is kept within 210 the reloc. Anything in the data should be ignored. 211 212| save %sp,-112,%sp 213| sethi %hi(_foo+0x12345678),%g2 214| ldsb [%g2+%lo(_foo+0x12345678)],%i0 215| ret 216| restore 217 218 Both relocs contain a pointer to <<foo>>, and the offsets 219 contain junk. 220 221|RELOCATION RECORDS FOR [.text]: 222|offset type value 223|00000004 HI22 _foo+0x12345678 224|00000008 LO10 _foo+0x12345678 225| 226|00000000 9de3bf90 ; save %sp,-112,%sp 227|00000004 05000000 ; sethi %hi(_foo+0),%g2 228|00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 229|0000000c 81c7e008 ; ret 230|00000010 81e80000 ; restore 231 232 o <<howto>> 233 234 The <<howto>> field can be imagined as a 235 relocation instruction.

Some targets arrange for 661 the addend to be the negative of the position of the location 662 within the section; for example, i386-aout does this. For 663 i386-aout, pcrel_offset is FALSE. Some other targets do not 664 include the position of the location; for example, m88kbcs, 665 or ELF. For those targets, pcrel_offset is TRUE. 666 667 If we are producing relocatable output, then we must ensure 668 that this reloc will be correctly computed when the final 669 relocation is done. If pcrel_offset is FALSE we want to wind 670 up with the negative of the location within the section, 671 which means we must adjust the existing addend by the change 672 in the location within the section. If pcrel_offset is TRUE 673 we do not want to adjust the existing addend at all. 674 675 FIXME: This seems logical to me, but for the case of 676 producing relocatable output it is not what the code 677 actually does.

I am fairly certain that patch will break coff-i386 (e.g., 722SCO); see coff_i386_reloc in coff-i386.c where I worked around the 723problem in a different way. There may very well be a reason that the 724code works as it does. 725 726Hmmm. The first obvious point is that bfd_perform_relocation should 727not have any tests that depend upon the flavour. It's seem like 728entirely the wrong place for such a thing. The second obvious point 729is that the current code ignores the reloc addend when producing 730relocatable output for COFF. That's peculiar. In fact, I really 731have no idea what the point of the line you want to remove is. 732 733A typical COFF reloc subtracts the old value of the symbol and adds in 734the new value to the location in the object file (if it's a pc 735relative reloc it adds the difference between the symbol value and the 736location). When relocating we need to preserve that property. 737 738BFD handles this by setting the addend to the negative of the old 739value of the symbol. Unfortunately it handles common symbols in a 740non-standard way (it doesn't subtract the old value) but that's a 741different story (we can't change it without losing backward 742compatibility with old object files) (coff-i386 does subtract the old 743value, to be compatible with existing coff-i386 targets, like SCO). 744 745So everything works fine when not producing relocatable output. When 746we are producing relocatable output, logically we should do exactly 747what we do when not producing relocatable output. Therefore, your 748patch is correct. In fact, it should probably always just set 749reloc_entry->addend to 0 for all cases, since it is, in fact, going to 750add the value into the object file. This won't hurt the COFF code, 751which doesn't use the addend; I'm not sure what it will do to other 752formats (the thing to check for would be whether any formats both use 753the addend and set partial_inplace). 754 755When I wanted to make coff-i386 produce relocatable output, I ran 756into the problem that you are running into: I wanted to remove that 757line. Rather than risk it, I made the coff-i386 relocs use a special 758function; it's coff_i386_reloc in coff-i386.c. The function 759specifically adds the addend field into the object file, knowing that 760bfd_perform_relocation is not going to. If you remove that line, then 761coff-i386.c will wind up adding the addend field in twice. It's 762trivial to fix; it just needs to be done. 763 764The problem with removing the line is just that it may break some 765working code. With BFD it's hard to be sure of anything. The right 766way to deal with this is simply to build and test at least all the 767supported COFF targets. It should be straightforward if time and disk 768space consuming. For each target: 769 1) build the linker 770 2) generate some executable, and link it using -r (I would 771 probably use paranoia.o and link against newlib/libc.a, which 772 for all the supported targets would be available in 773 /usr/cygnus/progressive/H-host/target/lib/libc.a). 774 3) make the change to reloc.c 775 4) rebuild the linker 776 5) repeat step 2 777 6) if the resulting object files are the same, you have at least 778 made it no worse 779 7) if they are different you have to figure out which version is 780 right 781*/ 782 relocation -= reloc_entry->addend; 783 reloc_entry->addend = 0; 784 } 785 else 786 { 787 reloc_entry->addend = relocation; 788 } 789 } 790 } 791 else 792 { 793 reloc_entry->addend = 0; 794 } 795 796 /* FIXME: This overflow checking is incomplete, because the value 797 might have overflowed before we get here.

When 4201 the --gc-sections option is given, the linker will zero out the entries 4202 that are not used, so that the code for those functions need not be 4203 included in the output. 4204 4205 VTABLE_INHERIT is a zero-space relocation used to describe to the 4206 linker the inheritance tree of a C++ virtual function table. The 4207 relocation's symbol should be the parent class' vtable, and the 4208 relocation should be located at the child vtable. 4209 4210 VTABLE_ENTRY is a zero-space relocation that describes the use of a 4211 virtual function table entry. The reloc's symbol should refer to the 4212 table of the class mentioned in the code. Off of that base, an offset 4213 describes the entry that is being used. For Rela hosts, this offset 4214 is stored in the reloc's addend.
