The contents of the test program are diverse, from simple operation checks to those that include complex algorithms.

• Variables (auto, decltype, etc.)
• Type declarations (in-block declarations, etc.)
• Type qualifiers (such as using macros for const constants)
• Classes (public/private, friend, inheritance, etc.)
• Templates (function, class, variable, variable-length argument, etc.)
• Operators (:: operators, reference operators, new/delete, etc.)
• Control structure (The range-based for statement, Initializing statements for if and switch statements, etc.)
• Casts (function format, etc.)
• Functions (overload, inline, lambda expressions, etc.)

..... and more

• ISO TR
• ACE

• Four arithmetic operations and compound operations using fixed-point type
• Verification of overflow processing using overflow type specifier (saturation/modwrap)
• Verification of fixed-point type conversion processing
