Tests covering ANSI+ C Standard Compatibility

[andrew-johnson-4]

In the tests/c/*.c directory, these files are used to test C compatibility. These are just normal C program source files. The LM compiler is now working to accept C input.

How it works

• These files should NOT use the C preprocessor.
• Any features other than preprocessing are valid to test
• tests should not be longer than 30 lines of code
• when tested, LM parses the file and generates a new file "tmp.c" which should be identical aside from whitespace

What to submit

To add a test case

• create a new file tests/c/[test name].c exhibiting the C feature that you wish to test
• create an empty file tests/c/[test name].c.out (silence here indicates success)
• create an empty file tests/c/[test name].c.skip
  • this file marks the test as skippable (will be removed as C frontend improves)
