With this Symbol has the same size as before, but DefinedRegular goes
from 72 to 64 bytes.
I also find this a bit easier to read. There are fewer places
initializing File for example.
This has a small but measurable speed improvement on all tests (1%
max).

This adds:
- NetBSD specific aliases for renamed syscalls,
- differentiate internal_syscall, internal_syscall64, internal_syscall_ptr as there are various types of syscalls on NetBSD.

Previously this code was doing std::sort on IdentifierInfo pointers. Now
it sorts alphabetically by platform name.
This should de-flake clang/test/Index/availability.c, which was failing
non-deterministically for me.

Summary:
Tools like clang that use RemoveFileOnSignal on their output files
weren't actually able to clean up their outputs before this change. Now
the call to llvm::sys::fs::remove succeeds and the temporary file is
deleted. This is a stop-gap to fix clang before implementing the
solution outlined in PR34070.

This change adds the "-O binary" flag which directs llvm-objcopy to
output the object file to the same format as GNU objcopy does when given
the flag "-O binary". This was done by splitting the Object class into
two subclasses ObjectELF and ObjectBianry which each output a different
format but relay on the same code to read in the Object in Object.

Summary:
Last one of the `pvalloc` overflow checks!
`CheckForPvallocOverflow` was introduced with D35818 to detect when `pvalloc`
would wrap when rounding up to the next multiple of the page size.
Add this check to ASan's `pvalloc` implementation.

Its sole purpose was to avoid spreading around ifdefs related to
building global-isel. Since r309990, GlobalISel is not optional anymore,
thus, we can get rid of this mechanism all together.

Summary:
The regular expression to match STL allocators can't easily account for
C++ mangling compression and fails to match some valid instances of STL
allocators. Perform this logic in clang instead.

had no way to dump them. This patch adds dumping support,
along with some tests that LLD actually dumps them correctly.

Arguments, passed to the outlined function, must have correct address
space info for proper Debug info support. Patch sets global address
space for arguments that are mapped and passed by reference.
Also, cuda-gdb does not handle reference types correctly, so reference
arguments are represented as pointers.

Summary:
Previously, STL allocators were blacklisted in compiler_rt's
cfi_blacklist.txt because they mandated a cast from void* to T* before
object initialization completed. This change moves that logic into the
front end because C++ name mangling supports a substitution compression
mechanism for symbols that makes it difficult to blacklist the mangled
symbol for allocate() using a regular expression.

HasDeclarationMatcher did not handle DeducedType, it always returned false for deduced types.
So with code like this:
struct X{};
auto x = X{};
This did no longer match:
varDecl(hasType(recordDecl(hasName("X"))))
Because HasDeclarationMatcher didn't resolve the DeducedType of x.

This adds support for the main 128-bit atomic operations,
using the SystemZ instructions LPQ, STPQ, and CDSG.
Generating these instructions is a bit more complex than usual
since the i128 type is not legal for the back-end. Therefore,
we have to hook the LowerOperationWrapper and ReplaceNodeResults
TargetLowering callbacks.
llvm-svn: 310094
We currently emit a serialization operation (bcr 14, 0) before every
atomic load and after every atomic store. This is overly conservative.
The SystemZ architecture actually does not require any serialization
for atomic loads, and a serialization after an atomic store only if
we need to enforce sequential consistency. This is what other compilers
for the platform implement as well.
