The following tests explicitly check for .loc and .file directives, which is not currently supported. Disable these tests on AIX for now. Reviewed By: shchenz Differential Revision: https://reviews.llvm.org/D111346
For Clang, `MCUseDwarfDirectory` is true by default for the majority cases (-fintegrated-as or -gdwarf-5; most targets use -fintegrated-as by default). Defaulting MCUseDwarfDirectory to true can reduce the differences between clang and llc. Reviewed By: #debug-info, dblaikie Differential Revision: https://reviews.llvm.org/D105856
D73568 removed the lit feature object-emission, because it was introduced for a target which did not support the integrated assembler, and that target no longer required the feature. XCore still does not support the integrated assembler, so a build with XCore as the default target fails tests requiring object-emission. This issue was not publicly visible because there was not a buildbot for XCore as the default target. We fixed the failures downstream. We now have builder clang-xcore-ubuntu-20-x64 on the staging buildmaster, which shows the failures. We would like to make upstream build green. Omit DebugInfo/Generic on XCore to avoid annotating 70 separate files. Differential Revision: https://reviews.llvm.org/D98508
Summary: The lit feature object-emission was added because Hexagon did not support the integrated assembler, so some tests needed to be turned off with a Hexagon target. Hexagon now supports the integrated assembler, so this feature can be removed.

In r319995, we fixed the line table format to version 2 on Darwin because dsymutil didn't yet understand the new format which caused test failures for the LLDB bots. This has been resolved in the meantime so there's no reason to keep this limitation. rdar://problem/35968332 llvm-svn: 342136
On Darwin we pin the DWARF line tables to version 2. Stop doing so for DWARF v5 and later. Differential revision: https://reviews.llvm.org/D49381 llvm-svn: 339288
In some cases, for example when compiling a preprocessed file, the front-end is not able to provide an MD5 checksum for all files. When that happens, omit the MD5 checksums from the final DWARF, because DWARF doesn't have a way to indicate that some but not all files have a checksum. When assembling a .s file, and some but not all .file directives provide an MD5 checksum, issue a warning and don't emit MD5 into the DWARF. Fixes PR37623.

DWARF v5 specifies that the root file (also given in the DW_AT_name attribute of the compilation unit DIE) should be emitted explicitly to the line table's list of files. This makes the line table more independent of the .debug_info section. We emit the new syntax only for DWARF v5 and later. Fixes the bug found by asan. Also XFAIL the new test for Darwin, which is stuck on DWARF v2, and fix up other tests so they stop failing on Windows. Last but not least, don't break "clang -g" of an assembler file that has .file directives in it. Differential Revision: https://reviews.llvm.org/D44054 llvm-svn: 328805
