If the parameter to a CONSTH instruction is a relocatable type, two

relocation records are written. The first has an r_type of R_IHIHALF

|
(33 octal) and a normal r_vaddr and r_symndx. The second relocation
|

|
record has an r_type of R_IHCONST (34 octal), a normal r_vaddr (which
|
||||||
|
is redundant), and an r_symndx containing the 32-bit constant offset
|
||||||
|
to the relocation instead of the actual symbol table index. This
|
||||||
|
second record is always written, even if the constant offset is zero.
|

The constant fields of the instruction are set to zero. */
