-fsanitize=function: use type hashes instead of RTTI objects

Currently we use RTTI objects to check type compatibility. To support non-unique
RTTI objects, commit 5745eccef54ddd3caca278d1d292a88b2281528b added a
`checkTypeInfoEquality` string matching to the runtime.
The scheme is inefficient.

```
_Z1fv:
  .long   846595819                    # jmp
  .long   .L__llvm_rtti_proxy-_Z3funv
  ...

main:
  ...

  movslq  4(%rsi), %rax
  movq    (%rax,%rsi), %rdx
  # Is it the desired typeinfo object?
  leaq    _ZTIFvvE(%rip), %rax
  # If not, call __ubsan_handle_function_type_mismatch_v1, which may recover if checkTypeInfoEquality allows
  cmpq    %rax, %rdx
  jne     .LBB1_2
  ...

.section        .data.rel.ro,"aw",@progbits
  .p2align        3, 0x0
.L__llvm_rtti_proxy:
  .quad   _ZTIFvvE
```

Let's replace the indirect `_ZTI` pointer with a type hash similar to
`-fsanitize=kcfi`.

```
_Z1fv:
  .long   3238382334
  .long   2772461324  # type hash

main:
  ...
  # Load the second word (callee type hash) and check whether it is expected
  cmpl    $-1522505972, -4(%rax)
  # If not, fail: call __ubsan_handle_function_type_mismatch
  jne     .LBB2_2
```

The RTTI object derives its name from `clang::MangleContext::mangleCXXRTTI`,
which uses `mangleType`. `mangleTypeName` uses `mangleType` as well. So the
type compatibility change is high-fidelity.

Since we no longer need RTTI pointers in
`__ubsan::__ubsan_handle_function_type_mismatch_v1`, let's switch it back to
version 0, the original signature before
e215996a2932ed7c472f4e94dc4345b30fd0c373 (2019).
`__ubsan::__ubsan_handle_function_type_mismatch_abort` is not
recoverable, so we can revert some changes from
e215996a2932ed7c472f4e94dc4345b30fd0c373.

[lldb] Fix process pid parsing issue

This patch should fix an issue when parsing the process pid and setting
it in the scripted process.

It can happen that the `crashlog.process_id` attribute is sometimes
parsed as a string. That would cause the scripted process to pick the
default value (0).

To address that, this patch makes sure that the parsed attributed is
converted to the integer type before passing it to the scripted process.

Med Ismail Bennani [Sat, 20 May 2023 03:05:05 +0000 (20:05 -0700)]
[lldb/crashlog] Load inlined symbol into interactive crashlog

Sometimes, crash reports come with inlined symbols. These provide the
exact stacktrace from the user binary.

However, when investigating a crash, it's very likely that the images related
to the crashed thread are not available on the debugging user system or
that the versions don't match. This causes interactive crashlog to show
a degraded backtrace in lldb.

This patch aims to address that issue, by parsing the inlined symbols
from the crash report and load them into lldb's target.

This patch is a follow-up to 27f27d1, focusing on inlined symbols
loading from legacy (non-json) crash reports.

To do so, it updates the stack frame regular expression to make the
capture groups more granular, to be able to extract the symbol name, the
offset and the source location if available, while making it more
maintainable.

So now, when parsing the crash report, we build a data structure
containing all the symbol information for each stackframe. Then, after
launching the scripted process for interactive mode, we write a JSON
symbol file for each module, only containing the symbols that it contains.

Finally, we load the json symbol file into lldb, before showing the user
the process status and backtrace.

GlobalISel: Move fconstant matching into tablegen

I don't really understand what the point of wip_match_opcode is.
It doesn't seem to have any purpose other than to list opcodes
to have all the logic in pure C++. You can't seem to  use it to
select multiple opcodes in the same way you use match.

Something is wrong with it, since the match emitter prints
"errors" if an opcode is covered by wip_match_opcode and
then appears in another pattern. For exmaple with this patch,
you see this several times in the build:

  error: Leaf constant_fold_fabs is unreachable
  note: Leaf idempotent_prop will have already matched

The combines are actually produced and the tests for them
do pass, so this seems to just be a broken warning.

We never set the value-dependent bit for the VAArgExpr before this
patch, this was fine becase the dependent-type TypoExpr was always
resolved before checking the operands (see https://github.com/llvm/llvm-project/blob/main/clang/lib/Sema/SemaExpr.cpp#L21173-L21180)

Now we have enabled the dependence by default for C, the typo expr is
not early resolved before checking rather than delayed (share the same
codepath with C++).

The fix is to propagate the value-dependent bit for VAArgExpr where it contains
a TypoExpr, so that the AST node can be handled properly.

[bazel] Rework zlib dependency

Removes the `BAZEL_LLVM_ZLIB_STRATEGY` environment variable and instead

to true.

To migrate:
    * The previous "external" strategy is the default. May be explicitly

      variants you can use the BUILD file at `third_party_build/zlib.BUILD`

      directly.
    * The previous "disable" strategy may be enabled with
      `--@llvm_zlib//:llvm_enable_zlib=false`.
    * The previous "system" strategy has been removed since it breaks
      hermeticity. If you need the "system" setup, use the "external"

[1/11][IR] Permit load/store/alloca for struct of the same scalable vector type

This patch-set aims to simplify the existing RVV segment load/store
intrinsics to use a type that represents a tuple of vectors instead.

To achieve this, first we need to relax the current limitation for an
aggregate type to be a target of load/store/alloca when the aggregate
type contains homogeneous scalable vector types. Then to adjust the
prolog of an LLVM function during lowering to clang. Finally we
re-define the RVV segment load/store intrinsics to use the tuple types.

The pull request under the RVV intrinsic specification is
riscv-non-isa/rvv-intrinsic-doc#198

---

This is the 1st patch of the patch-set. This patch is originated from
D98169.

This patch allows aggregate type (StructType) that contains homogeneous
scalable vector types to be a target of load/store/alloca. The RFC of
this patch was posted in LLVM Discourse.

https://discourse.llvm.org/t/rfc-ir-permit-load-store-alloca-for-struct-of-the-same-scalable-vector-type/69527

The main changes in this patch are:

Extend `StructLayout::StructSize` from `uint64_t` to `TypeSize` to
accommodate an expression of scalable size.

Allow `StructType:isSized` to also return true for homogeneous
scalable vector types.

Let `Type::isScalableTy` return true when `Type` is `StructType`
and contains scalable vectors

Extra description is added in the LLVM Language Reference Manual on the
relaxation of this patch.
