(even though theDWARF doesn't have this string in it - it's something to do with thestring lldb generates for itself using clang)This reverts commit 277623f4d5a672d707390e2c3eaf30a9eb4b075c.

However, functions which take a pointer or reference to theoriginal type are compiled assuming the original alignment. Therefore when anysuch function is passed an object of the new, less-aligned type, an alignmentfault can occur. In particular, this applies to the constructor, which isdefined for the original type and called for the less-aligned object.This change adds a warning whenever an pointer or reference to an object ispassed to a function that was defined for a more-aligned type.The calls to ASTContext::getTypeAlignInChars seem change the order in whichrecord layouts are evaluated, which caused changes to the output of-fdump-record-layouts. As such some tests needed to be updated: * Use CHECK-LABEL rather than counting the number of "Dumping AST Record Layout" headers. * Check for end of line in labels, so that struct B1 doesn't match struct B etc. * Add --strict-whitespace, since the whitespace shows meaningful structure. * The order in which record layouts are printed has changed in some cases. * clang-format for regions changedDifferential Revision: https://reviews.llvm.org/D97187 List of files: /llvm-project-15.0.7/clang/test/Layout/ms-x86-empty-virtual-base.cpp Fri, 19 Feb 2021 17:33:56 +0000 Tomas Matheson <tomas.matheson@arm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Layout/ms-x86-empty-virtual-base.cpp#0d461693 Fix the layout of bitfields in ms_struct unions: theiralignment is ignored, and they always allocate a completestorage unit.Also, change the dumping of AST record layouts: use the morereadable C++-style dumping even in C, include bitfield offsetinformation in the dump, and don't print sizeof/alignofinformation for fields of record type, since we don't do sofor bases or other kinds of field.rdar://22275433llvm-svn: 245514 List of files: /llvm-project-15.0.7/clang/test/Layout/ms-x86-empty-virtual-base.cpp Wed, 19 Aug 2015 22:42:36 +0000 John McCall <rjmccall@apple.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Layout/ms-x86-empty-virtual-base.cpp#674cf268 __declspec is not a core Clang language extension.

It's no longer possible to do weird combinations.To be able to run a test with a specific ABI without constraining it to aspecific triple, new substitutions are added to lit: %itanium_abi_triple and%ms_abi_triple can be used to get the current target triple adjusted to thedesired ABI. For example, if the test suite is running with the i686-pc-win32target, %itanium_abi_triple will expand to i686-pc-mingw32.Differential Revision: http://llvm-reviews.chandlerc.com/D2545llvm-svn: 199250 List of files: /llvm-project-15.0.7/clang/test/Layout/ms-x86-empty-virtual-base.cpp Tue, 14 Jan 2014 19:35:09 +0000 Hans Wennborg <hans@hanshq.net> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Layout/ms-x86-empty-virtual-base.cpp#d640d7d9 [ms-abi] Refactor Microsoft Record LayoutThis patch refactors microsoft record layout to be more "natural".
