/* This is the relocation function for the RS/6000/POWER/PowerPC.
This is currently the only processor which uses XCOFF; I hope that
will never change.
- I took the relocation type definitions from two documents:
+ The original version was based on two documents:
the PowerPC AIX Version 4 Application Binary Interface, First
Edition (April 1992), and the PowerOpen ABI, Big-Endian
32-Bit Hardware Implementation (June 30, 1994). Differences
between the documents are noted below.
+ Now, IBM has released an official documentation about XCOFF
+ format:
+ https://www.ibm.com/support/knowledgecenter/ssw_aix_72/filesreference/XCOFF.html
Unsupported r_type's
osym = oTOC + on
oinsn = on + o
so we must change insn by on - in.
+ This relocation allows the linker to perform optimizations
+ by transforming a load instruction into a add-immediate
+ when possible. The relocation is, then, changed to R_TRLA
+ in the output file.
+ TODO: Currently, the optimisation isn't implemented.
+
+ R_TRL:
+ TOC relative relocation. Same as R_TOC, except that
+ the optimization isn't allowed
+
+ R_TRLA:
+ TOC relative relocation. This is a TOC relative load
+ address instruction which have been changed to an add-
+ immediate instruction.
R_GL:
GL linkage relocation. The value of this relocation
- is the address of the entry in the TOC section.
+ is the address of the external symbol 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_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_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_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.
+
+ R_REF:
+ Not a relocation but a way to prevent the garbage
+ collector of AIX linker to remove symbols.
+ This is not needed in our case.
R_BA:
- Absolute branch. We don't want to mess with the lower
- two bits of the instruction.
+ The PowerOpen ABI says this is the same as R_RBA.
+
+ R_RBA:
+ Absolute branch which may be modified to become a
+ relative branch.
+
+ R_BR:
+ The PowerOpen ABI says this is the same as R_RBR.
+
+ R_RBR:
+ A relative branch which may be modified to become an
+ absolute branch.
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_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_RBAC:
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_TLS:
+ Thread-local storage relocation using general-dynamic
+ model.
- 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_TLS_IE:
+ Thread-local storage relocation using initial-exec model.
- R_RBR:
- A relative branch which may be modified to become an
- absolute branch.
+ R_TLS_LD:
+ Thread-local storage relocation using local-dynamic model.
- 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_TLS_LE:
+ Thread-local storage relocation using local-exec model.
- 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.
+ R_TLSM:
+ Tread-local storage relocation used by the loader.
+
+ R_TLSML:
+ Tread-local storage relocation used by the loader.
+
+ R_TOCU:
+ Upper TOC relative relocation. The value is the
+ high-order 16 bit of a TOC relative relocation.
+
+ R_TOCL:
+ Lower TOC relative relocation. The value is the
+ low-order 16 bit of a TOC relative relocation.
