◆ decodeBBAddrMap()
Returns a vector of BBAddrMap structs corresponding to each function within the text section that the SHT_LLVM_BB_ADDR_MAP section Sec is associated with.
If the current ELFFile is relocatable, a corresponding RelaSec must be passed in as an argument. Optional out variable to collect all PGO Analyses. New elements are only added if no error occurs. If not provided, the PGO Analyses are decoded then ignored.

◆ getDynSymtabSize()
This function determines the number of dynamic symbols.
It reads section headers first. If section headers are not available, the number of symbols will be inferred by parsing dynamic hash tables.

Returns a map from every section matching IsMatch to its relocation section, or nullptr if it has no relocation section.
This function returns an error if any of the IsMatch calls fail or if it fails to retrieve the content section of any relocation section.
