Adding together in a single commit as their implementations are linked. Only supported for DAP debuggers. These two commands make it a bit easier to drive dexter: DexStepFunction tells dexter to step-next though a function and DexContinue tells dexter to continue (run free) from one breakpoint to another within the current DexStepFunction function. When the DexStepFunction function breakpoint is triggered, dexter sets an instruction breakpoint at the return-address. This is so that stepping can resume in any other DexStepFunctions deeps in the call stack.

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.
