Jonas Devlieghere 32211fda29 [Tests] Split inferior crashing tests
We noticed that TestInferiorCrashing.py and TestRecursiveInferior.py are
the second and third slowest tests in the test suite. Splitting them up
allows lit to schedule them more effectively.

Jonas Devlieghere 2fa67f442a [dotest] Set environment variables after potentialy clearing others.
Dotest contains code to clear DYLD_LIBRARY_PATH for the inferior to not
propagate sanitized builds. However, it's possible that we want to
inject a different library path with `--inferior-env`. To make that work
correctly, we need to do that *after* clearing DYLD_LIBRARY_PATH.

Michal Gorny e1c159e86a [lldb] [Process/NetBSD] Report stopped process on SIGSTOP
Mark the process as stopped when SIGSTOP arrives.  This is necessary
for lldb-server to generate correct response to 'process interrupt',
and therefore to prevent the whole stack crashing when process
is stopped.

Thanks to Pavel Labath for the tip.

Pavel Labath ee74c9e5fd LLGS: fix tracking execve on linux
Summary:
Due to a logic error, lldb-server ended up asserting/crashing every time
the debugged process attempted an execve(). This fixes the error, and
extends TestExec to work on other platforms too. The "extension"
consists of avoiding non-standard posix_spawn extensions and using the
classic execve() call, which should be available on any platform that
actually supports re-execing. I change the test decorator from
@skipUnlessDarwin to @skipIfWindows.

Jan Kratochvil 8693f8f9c1 [lldb] Fix occasional hangs of VSCode testcases
On slower machines the vscode testcases were sometimes hanging:

A reproducer of the racy bug for send_recv():
#         self.send_packet(command)
#+        import time
#+        time.sleep(1)
#         done = False

I guess `request_continue` was probably originally intended to be synchronous
but then it isn't and this code has been leftover there.

Raphael Isemann ca9dfdfaec [lldb] Fix crash when looking up type coming from the ClangModuleDeclVendor
Summary:
We assume in LLDB that every type comes from an ASTContext with an associated ClangASTContext.
However the types inside the ClangModuleDeclVendor don't have a ClangASTContext so we end up
crashing whenever we create a CompilerType for one of these types.

Simplest way to trigger this bug is to just look up NSObject from a module:
   (lldb) expr @import Foundation
   (lldb) type lookup NSObject
   Assertion failed: (m_type_system != nullptr), function CompilerType, file /Users/teemperor/llvm1/llvm-project/lldb/source/Symbol/CompilerType.cpp, line 39.

This patch just creates a ClangASTContext for the ASTContext used by ClangModuleDeclVendor.

Joseph Tremoulet 3fd917d886 Support Linux signal return trampolines in frame initialization
Summary:
Add __kernel_rt_sigreturn to the list of trap handlers for Linux (it's
used as such on aarch64 at least), and __restore_rt as well (used on
x86_64).

Skip decrement-and-recompute for trap handlers in
InitializeNonZerothFrame, as signal dispatch may point the child frame's
return address to the start of the return trampoline.

Parse the 'S' flag for signal handlers from eh_frame augmentation, and
propagate it to the unwind plan.

Jim Ingham fa6199bc5d Add an expectedFailure test for type finding.
When two .c files define a type of the same name, lldb
just picks one and uses it regardless of context.  That is
not correct.  When stopped in a frame in one of the .c files
that define this type, it should use that local definition.

This commit just adds a test that checks for the correct
behavior.  It is currently xfailed.

Raphael Isemann e21fc8770c Add offsetof support to expression evaluator.
Summary:
We currently don't support offsetof in the expression evaluator as it is implemented as a macro
(which then calls __builtin_offsetof) in stddef.h. The best solution would be to include that
header (or even better, import Clang's builtin module), but header-parsing and
(cross-platform) importing modules is not ready yet.

Until we get this working with modules I would say we add the macro to our existing macro list
as we already do with other macros from stddef.h/stdint.h. We should be able to drop all of them
once we can import the relevant modules by default.

Jason Molenda 1375659e0f Ah, forgot a debug line I left in the dsym-for-uuid.sh script

Jason Molenda be4be6120f Add support to ProcessMachCore::DoLoadCore to handle an EFI UUID str.
If a core file has an EFI version string which includes a UUID
(similar to what it returns for the kdp KDP_KERNELVERSION packet)
in the LC_IDENT or LC_NOTE 'kern ver str' load command.  In that
case, we should try to find the binary and dSYM for the UUID
listed.  The dSYM may have python code which knows how to relocate
the binary to the correct address in lldb's target section load
list and loads other ancillary binaries.

The test case is a little involved,

1. it compiles an inferior hello world apple (a.out),
2. it compiles a program which can create a corefile manually
   with a specific binary's UUID encoded in it,
3. it gets the UUID of the a.out binary,
4. it creates a shell script, dsym-for-uuid.sh, which will
   return the full path to the a.out + a.out.dSYM when called
   with teh correct UUID,
5. it sets the LLDB_APPLE_DSYMFORUUID_EXECUTABLE env var before
   creating the lldb target, to point to this dsym-for-uuid.sh,
6. runs the create-corefile binary we compiled in step #2,
7. loads the corefile from step #6 into lldb,
8. verifies that lldb loaded a.out by reading the LC_NOTE
   load command from the corefile, calling dsym-for-uuid.sh with
   that UUID, got back the path to a.out and loaded it.

whew!

Shafik Yaghmour a0858e2f20 Fix CreateFunctionTemplateSpecialization to prevent dangling poiner to stack memory
In ClangASTContext::CreateFunctionTemplateSpecializationInfo a TemplateArgumentList is allocated on the stack but is treated as if it is persistent in subsequent calls. When we exit the function func_decl will still point to the stack allocated memory. We will use TemplateArgumentList::CreateCopy instead which will allocate memory out of the DeclContext.

Disable colors so we don't risk having unexpected ANSI codes in the test

Gabor Marton aefcf5100a [ASTImporter] Fix LLDB lookup in transparent ctx and with ext src
Summary:
With LLDB we use localUncachedLookup(), however, that fails to find
Decls when a transparent context is involved and the given DC has
external lexical storage.  The solution is to use noload_lookup, which
works well with transparent contexts.  But, we cannot use only the
noload_lookup since the slow case of localUncachedLookup is still needed
in some other cases.

These other cases are handled in ASTImporterLookupTable, but we cannot
use that with LLDB since that traverses through the AST which initiates
the load of external decls again via DC::decls().

We must avoid loading external decls during the import becuase
ExternalASTSource is implemented with ASTImporter, so external loads
during import results in uncontrolled and faulty import.

Raphael Isemann 2bc8ab6852 [lldb] Make TestDeletedExecutable more reliable
Summary:
It seems that calling Popen can return to the caller before the started process has read all the needed information
from its executable. This means that in case we delete the executable while the process is still starting up,
this test will create a zombie process which in turn leads to a failing test. On my macOS system this happens quite frequently.

This patch fixes this by letting the test synchronize with the inferior after it has started up.
