+
+ Unsupported r_type's
+
+ R_RTB:
+ R_RRTBI:
+ R_RRTBA:
+
+ These relocs are defined by the PowerPC ABI to be
+ relative branches which use half of the difference
+ between the symbol and the program counter. I can't
+ quite figure out when this is useful. These relocs are
+ not defined by the PowerOpen ABI.
+
+ Supported r_type's
+
+ R_POS:
+ Simple positive relocation.
+
+ R_NEG:
+ Simple negative relocation.
+
+ R_REL:
+ Simple PC relative relocation.
+
+ R_TOC:
+ TOC relative relocation. The value in the instruction in
+ the input file is the offset from the input file TOC to
+ the desired location. We want the offset from the final
+ TOC to the desired location. We have:
+ isym = iTOC + in
+ iinsn = in + o
+ osym = oTOC + on
+ oinsn = on + o
+ so we must change insn by on - in.
+
+ R_GL:
+ GL linkage relocation. The value of this relocation
+ is the address of the entry in the TOC section.
+
+ R_TCL:
+ Local object TOC address. I can't figure out the
+ difference between this and case R_GL.
+
+ R_TRL:
+ TOC relative relocation. A TOC relative load instruction
+ which may be changed to a load address instruction.
+ FIXME: We don't currently implement this optimization.
+
+ R_TRLA:
+ TOC relative relocation. This is a TOC relative load
+ address instruction which may be changed to a load
+ instruction. FIXME: I don't know if this is the correct
+ implementation.
+
+ R_BA:
+ Absolute branch. We don't want to mess with the lower
+ two bits of the instruction.
+
+ R_CAI:
+ The PowerPC ABI defines this as an absolute call which
+ may be modified to become a relative call. The PowerOpen
+ ABI does not define this relocation type.
+
+ R_RBA:
+ Absolute branch which may be modified to become a
+ relative branch.
+
+ R_RBAC:
+ The PowerPC ABI defines this as an absolute branch to a
+ fixed address which may be modified to an absolute branch
+ to a symbol. The PowerOpen ABI does not define this
+ relocation type.
+
+ R_RBRC:
+ The PowerPC ABI defines this as an absolute branch to a
+ fixed address which may be modified to a relative branch.
+ The PowerOpen ABI does not define this relocation type.
+
+ R_BR:
+ Relative branch. We don't want to mess with the lower
+ two bits of the instruction.
+
+ R_CREL:
+ The PowerPC ABI defines this as a relative call which may
+ be modified to become an absolute call. The PowerOpen
+ ABI does not define this relocation type.
+
+ R_RBR:
+ A relative branch which may be modified to become an
+ absolute branch.
+
+ R_RL:
+ The PowerPC AIX ABI describes this as a load which may be
+ changed to a load address. The PowerOpen ABI says this
+ is the same as case R_POS.
+
+ R_RLA:
+ The PowerPC AIX ABI describes this as a load address
+ which may be changed to a load. The PowerOpen ABI says
+ this is the same as R_POS.
