Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific 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 the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

PR5483: Generate missing form of destructor when it is virtual. (Someone more familiar with this stuff should double-check that there isn't some more general rule; this is purely from inspecting g++ output.) llvm-svn: 88755 2009-11-14 12:19:37 +08:00			`// PR5483`

[CodeGen] Apply 'nonnull' and 'dereferenceable(N)' to 'this' pointer arguments. * Adds 'nonnull' and 'dereferenceable(N)' to 'this' pointer arguments * Gates 'nonnull' on -f(no-)delete-null-pointer-checks * Introduces this-nonnull.cpp and microsoft-abi-this-nullable.cpp tests to explicitly test the behavior of this change * Refactors hundreds of over-constrained clang tests to permit these attributes, where needed * Updates Clang12 patch notes mentioning this change Reviewed-by: rsmith, jdoerfert Differential Revision: https://reviews.llvm.org/D17993 2020-11-17 07:04:55 +08:00			`// CHECK-LABEL: define {{.}}void @_ZN3FooD0Ev(%class.Foo {{[^,]*}} %this) unnamed_addr`
