CS134b Lab 2: Lexing and Parsing

Here are the AST files and run results on the test programs:

• test1.c: test1.ast, test1.out
• test2.c: test2.ast, test2.out
• test3.c: test3.ast, test3.out

Bugs found after submission:

• We added UBAndOp and UPlusOp to the type unop and correspondingly modified files fc_ast_type.mlz, fc_ast_eval.ml and fc_ast_util.ml. All these changes are useless. The first one will never appear (since it is treated as addr_of and the second one can be omitted in parsing. Thus, those 3 files can be left unchaged.
• The variable declaration is wrong in the order. See lab3 README.
• The 3nd entry of FunDef should be return type, not the type of the whole function. See lab4 README.
