These are a burden to maintain & use hand crafted IR to test particular DWARF generation cases in LLVM. If someone thinks there's high value coverage here they can rephrase these as IR+dwarfdump tests in the LLVM regression suite so they'll be portable/easily executed by all developers. llvm-svn: 177182
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. Typically, test
cases included here includes debugger commands and intended debugger output
as comments in source file using DEBUGGER: and CHECK: as prefixes respectively.
For exmaple,
define i32 @f1(i32 %i) nounwind ssp {
; DEBUGGER: break f1
; DEBUGGER: r
; DEBUGGER: p i
; CHECK: $1 = 42
entry:
}
is a testcase where the debuger is asked to break at function 'f1' and
print value of argument 'i'. The expected value of 'i' is 42 in this case.
