// VxWorksSymTab_5_4 is a copy of VxWorksSymTab_6_1 with a different value for SYM_ENTRY_SIZE
// It was replaced at the request of a customer who tested that it worked with the slight modification
// VxWorksSymTab_6_1 is an adaptation of the vxWorksSymTab script. It was modified by a customer
// VxWorksSymTab_6_1 is an adaptation of the vxWorksSymTab script. It was modified by a customer
// to use a single loop, instead of two. It also added demangling of C++ symbol names - at least
// those that Ghidra knows how to demangle.
//
// Extracts all symbols in a VxWorks symbol table and disassembles
// the global functions. Any existing symbols in the Ghidra symbol table
// that collide with symbols defined in the VxWorks symbol table are deleted.
//
//
// The VxWorks symbol table is an array of symbol table entries [0..n-1]
// followed by a 32-bit value that is equal to n (number of sym tbl entries).
// Each entry in the array has the following structure:
