This makes the reader check the endianness of the object file its
given and behave appropriately. For the test I dug up a really old
linker and created a ppc-apple-darwin file for llvm-cov to read.

If `Verifier` has already found a failure, don't call
`DebugInfoVerifier`. The latter sometimes crashes in `DebugInfoFinder`
when the former would give a nice message. The only two cases I found
it crashing are explicit verifier tests I've added:
- test/Verifier/llvm.dbg.declare-expression.ll
- test/Verifier/llvm.dbg.value-expression.ll
However, I assume frontends with bugs will create invalid IR as well.
IMO, the `DebugInfoVerifier` should never crash (instead, it should fail
to verify), but subtleties like that will be easier to work out once
it's enabled again.
This is part of PR22777.
llvm-svn: 232418
As part of PR22777, fix testcases that fail the debug info verifier.
The changes fall into the following categories:
- Empty `filename:` fields in `MDFile`s. Compile units and some types
require non-empty filenames. A number of testcases have empty
filenames, probably due to hand-reduction of testcases.
- Not-quite empty arrays: `!{i32 0}`. This used to be equivalent in
the debug info schema to `!{}`. They cause problems for
`!MDSubroutineType`'s `types:` array, since it requires all operands
to be valid types. (Note that `!{null}` is the correct type array
for functions that take no arguments and return `void`.)
- Significantly bitrotted testcases. Nodes got left behind a few
upgrades ago because of missing or invalid tags.

The `eh_frame_ptr` field in the `.eh_frame_hdr` section contains an address
of the `.eh_frame` section. Using an absolute 32-bit format for encoding
of this field does not work for 64-bit targets. It is better to use a
relative format because it covers both 32-bit and 64-bit cases. Sure
this work if a distance between `.eh_frame_hdr` and `.eh_frame` sections
is less than 4 Gb but it is a rather correct assumption.

Now that we check `MDExpression` during `-verify` (r232299), make
the `DIExpression` wrapper more strict:
- remove redundant checks in `DebugInfoVerifier`,
- overload `get()` to `cast_or_null<MDExpression>` (superseding
`getRaw()`),
- stop checking for null in any accessor, and
- remove `DIExpression::Verify()` entirely in favour of
`MDExpression::isValid()`.
There is still some logic in this class, mostly to do with high-level
iterators; I'll defer cleaning up those until the rest of the wrappers
are similarly strict.

building its redecl chains, make sure we pull in the redeclarations of those
canonical declarations.
It's pretty difficult to reach a situation where we can find more canonical
declarations of an entity while building its redecl chains; I think the
provided testcase (4 modules and 7 declarations) cannot be reduced further.
llvm-svn: 232411
Clarify the logic in `DIType::Verify()` by checking `isBasicType()`
earlier, by skipping `else` after `return`s, and by documenting an
otherwise opaque check.
No functionality change.

Turns out `visitIntrinsicFunctionCall()` descends into all operands
already, so explicitly descending in `visitDbgIntrinsic()` (part of
r232296) isn't useful.

r231082) as confirmation.

This commit implements the behaviour of the SECTIONS linker script directive,
used to not only define a custom mapping between input and output sections, but
also order input sections in the output file. To do this, we modify
DefaultLayout with hooks at important places that allow us to re-order input
sections according to a custom order. We also add a hook in SegmentChunk to
allow us to calculate linker script expressions while assigning virtual
addresses to the input sections that live in a segment.
Not all SECTIONS constructs are currently supported, but only the ones that do
not use special sort orders. It adds two LIT test as practical examples of
which sections directives are currently supported.
In terms of high-level changes, it creates a new class "script::Sema" that owns
all linker script ASTs and the logic for linker script semantics as well.
ELFLinkingContext owns a single copy of Sema, which will be used throughout
the object file writing process (to layout sections as proposed by the linker
script).
Other high-level change is that the writer no longer uses a "const" copy of
the linking context. This happens because linker script expressions must be
calculated *while* calculating final virtual addresses, which is a very late
step in object file writing. While calculating these expressions, we need to
update the linker script symbol table (inside the semantics object), and, thus,
we are "modifying our context" as we prepare to write the file.

The test does the following:
1 - runs a program to main without the OS plug-in and verifies no OS threads are in the process
2 - loads the OS plug-in and verifies the 3 OS plug-in threads are now in the current process
3 - verify the register contents of each thread that shows up
4 - unload the python OS plug-in and verify that the OS threads are gone.

Also, change its return type to size_t to match the return types of
its callers.
With this change, std::vector and std::list data formatter tests
pass on Linux (when using libstdc++) with clang as well as with gcc.
These tests have also been enabled in this patch.

location data is available. If pragma handling wants to look up the
position, it finds the LLVM buffer and wants to compare it with the
special built-in buffer, failing badly. Extend to the special handling
of the built-in buffer to also check for the inline asm buffer. Expect
only a single asm buffer. Sort it between the built-in buffers and the
normal file buffers.

While there, respect the common format of the tests. For most other

Fix justify error for small structures bigger than 32 bits in fixed
arguments for MIPS64 big endian. There was a problem when small structures
are passed as fixed arguments. The structures that are bigger than 32 bits
but smaller than 64 bits were not left justified properly on MIPS64 big
endian. This is fixed by shifting the value to make it left justified when
appropriate.

I think the issue that caused the random failure has been fixed. So I am enabling the tests again on Linux.
There are still some tests that are skipped on Linux due to different output. Those will be handled separately.
Tested with dotest.py and with "make check-lldb" and there was no MI related failure.
