Cobol compiler respects syntax-only mode in code generation.
Cobol compiler now avoids crashes in syntax-only mode by returning early in code generation.
The Cobol compiler has been updated to properly honor the syntax-only mode during code generation. If syntax-only mode is active, the compiler will now return immediately without processing operands, preventing potential crashes that could occur when errors are encountered.
In Details
The parser_sleep and parser_compute functions in Cobol code generation now use RETURN_IF_PARSE_ONLY. This ensures that if the compiler is operating in a syntax-only mode (e.g., due to detected errors), it will exit early in the code generation phase, preventing further processing of operands and avoiding potential crashes.
For Context
- syntax-only mode
- A compiler mode where the compiler only checks the syntactic correctness of the code and does not generate machine code or perform semantic analysis. This is often used for early error detection.
- codegen
- Short for 'code generation', this is a phase in a compiler that takes an intermediate representation of the program and translates it into machine code or another lower-level representation.
