What are the types of errors found in different phases of compiler?

The types of errors found in  different phases of compiler-

• The lexical analyzer may be unable to proceed because the next token in the source program is misspelled.
• The syntaxb analyzer may be unable to infer structure for its input because a syntatic error such as a missing parenthesis has occured.
• The intermediate code generation detects an operator whose operands have incompatible types.
• The code optimizer, doing control flow analysis, may detect that certain statements can never be reached.
• The code generator may find a compiler - created control that is too large to fit in a word of the target machine.
• While entering information into the symbol table, the bookkeeping routine may discover an identifier.
