[llvm-commits] [PATCH] Introduce -dbg-quality test

[Török Edwin]

Hi Devang,

I've written the -dbg-quality pass (attached), and the
TEST.dbgquality.Makefile that tests the optimized (-std-compile-opts)
bitcode file. Should I also add a -std-link-opts tests? I think some
passes (such as -ipsccp) are only run there?
I've attached the results, the maximum score is 10000 (meaning all
non-alloca/non-dbgintrinsic instructions have debug info).
We have 79 tests at 10000 quality, the rest are between 5331 - 9999.

I've also found a bug: static constructors/destructors have out-of-file
line numbers often (PR5270). I've added a hack in -dbg-quality for now
that ignores those functions (denoted by a FIXME).

OK to commit, or should I wait till PR5270 is fixed so I can drop the
ugly hack?

Best regards,
--Edwin
