Get the MCSymbolizer's list of addresses that were referenced by symbolizable operands but not resolved to a symbol.
The caller (some code that is disassembling a section or other chunk of code) would typically create a synthetic label at each address and add them to its list of symbols in the section, before creating a new MCSymbolizer with the enhanced symbol list and retrying disassembling the section. The returned array is unordered and may have duplicates. The returned ArrayRef stops being valid on any call to or destruction of the MCSymbolizer object.

Try to add a comment on the PC-relative load.
For instance, in Mach-O, this is used to add annotations to instructions that use C string literals, as found in __cstring.

Try to add a symbolic operand instead of Value
to the MCInst.
Instead of having a difficult to read immediate, a symbolic operand would represent this immediate in a more understandable way, for instance as a symbol or an offset from a symbol. Relocations can also be used to enrich the symbolic expression.
Inst | - The MCInst where to insert the symbolic operand. |
cStream | - Stream to print comments and annotations on. |
Value | - Operand value, pc-adjusted by the caller if necessary. |
Address | - Load address of the instruction. |
IsBranch | - Is the instruction a branch? |
Offset | - Byte offset of the operand inside the inst. |
OpSize | - Size of the operand in bytes. |
InstSize | - Size of the instruction in bytes. |
