Reapply r257105 "[Verifier] Check that debug values have proper size" The follow extra changes were made to test cases: Manually making the variable be the actual type instead of a pointer to avoid pointer-size differences in generic code: LLVM :: DebugInfo/Generic/2010-03-24-MemberFn.ll LLVM :: DebugInfo/Generic/2010-04-06-NestedFnDbgInfo.ll LLVM :: DebugInfo/Generic/2010-05-03-DisableFramePtr.ll LLVM :: DebugInfo/Generic/varargs.ll Delete sizing information from debug info for the same reason (but the presence of the pointer was important to the test case): LLVM :: DebugInfo/Generic/restrict.ll LLVM :: DebugInfo/Generic/tu-composite.ll LLVM :: Linker/type-unique-type-array-a.ll LLVM :: Linker/type-unique-simple2.ll Fixing an incorrect DW_OP_deref LLVM :: DebugInfo/Generic/2010-05-03-OriginDIE.ll Fixing a missing DW_OP_deref LLVM :: DebugInfo/Generic/incorrect-variable-debugloc.ll Additionally, clang should no longer complain during bootstrap should no longer happen after r257534. The original commit message was: ``` Summary: Teach the Verifier to make sure that the storage size given to llvm.dbg.declare or the value size given to llvm.dbg.value agree with what is declared in DebugInfo. This is implicitly assumed in a number of passes (e.g. in SROA). Additionally this catches a number of common mistakes, such as passing a pointer when a value was intended or vice versa. One complication comes from stack coloring which modifies the original IR when it merges allocas in order to make sure that if AA falls back to the IR it gets the correct result. However, given this new invariant, indiscriminately replacing one alloca by a different (differently sized one) is no longer valid. Fix this by just undefing out any use of the alloca in a dbg.declare in this case. Additionally, I had to fix a number of test cases. Of particular note: - I regenerated dbg-changes-codegen-branch-folding.ll from the given source as it was affected by the bug fixed in r256077 - two-cus-from-same-file.ll was changed to avoid having a variable-typed debug variable as that would depend on the target, even though this test is supposed to be generic - I had to manually declared size/align for reference type. See also the discussion for D14275/r253186. - fpstack-debuginstr-kill.ll required changing `double` to `long double` - most others were just a question of adding OP_deref ``` git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@257550 91177308-0d34-0410-b5e6-96231b3b80d8 Keno Fischer 3 years ago
