-*- rst -*- This is a collection of tests to check debugging information generated by compiler. This test suite can be checked out inside clang/test folder. This will enable 'make test' for clang to pick up these tests. Some tests (in the 'llgdb-tests' directory) are written with debugger commands and checks for the intended debugger output in the source file, using DEBUGGER: and CHECK: as prefixes respectively. For example:: define i32 @f1(i32 %i) nounwind ssp { ; DEBUGGER: break f1 ; DEBUGGER: r ; DEBUGGER: p i ; CHECK: $1 = 42 entry: } is a testcase where the debugger is asked to break at function 'f1' and print value of argument 'i'. The expected value of 'i' is 42 in this case. Other tests are written for use with the 'Dexter' tool (in the 'dexter-tests' and 'dexter' directories respectively). These use a domain specific language in comments to describe the intended debugger experience in a more abstract way than debugger commands. This allows for testing integration across multiple debuggers from one input language. For example:: void __attribute__((noinline, optnone)) bar(int *test) {} int main() { int test; test = 23; bar(&test); // DexLabel('before_bar') return test; // DexLabel('after_bar') } // DexExpectWatchValue('test', '23', on_line='before_bar') // DexExpectWatchValue('test', '23', on_line='after_bar') Labels two lines with the names 'before_bar' and 'after_bar', and records that the 'test' variable is expected to have the value 23 on both of them.
