This patch is to fix the [[ https://github.com/llvm/llvm-project/issues/63045 | issue 63045]].
Look at the following code:
```
int main(int argc, char *argv[]) {
int arr[1000];
__asm movdir64b rax, ZMMWORD PTR [arr]
return 0;
}
```
Compiling this code using `clang -O0 -fasm-blocks bug.c` gives the a linker error.
The problem seems to be in the generated assembly. Following is the out put of `clang -S -O0 -fasm-blocks bug.c`:
```
movq %rsi, -16(%rbp)
#APP
movdir64b arr, %rax
#NO_APP
xorl %eax, %eax
```
The symbol `arr` should be replaced with some address like `-4(%rbp)`.
This makes me believe that issue is not in the linker, but with the ASM parser.
This issue originates with patch [D145893](https://reviews.llvm.org/D145893). And that's why reverting it fixes the issue. More specifically, the function [isMem512_GR64()](https://github.com/llvm/llvm-project/blob/

[AppleAccelTable][NFC] Refactor equal_range code
The current implementation of AppleAcceleratorTable::equal_range has a couple of
drawbacks:
1. Assumptions about how the hash table is structured are hard-coded throughout
the code. Unless you are familiar with the data layout of the table, it becomes
tricky to follow the code.
2. We currently load strings from the string table even for hashes that don't
match our current search hash. This is wasteful.
3. There is no error checking in most DataExtractor calls that can fail.
This patch cleans up (1) by making helper methods that hide the details of the
data layout from the algorithms relying on them. This should also help us in
future patches, where we want to expand the interface to allow iterating over
_all_ entries in the table, and potentially clean up the existing Iterator
class.
The changes above also fix (2), as the problem "just vanishes" when you have a
function called "idxOfHashInBucket(SearchHash)".
The changes above also fix (3), as having individual functions allow us to
expose the points in which reading data can fail. This is particularly important
as we would like to share this implementation with LLDB, which requires robust
error handling.
The changes above are also a step towards addressing a comment left by the
original author:
```
/// TODO: Generalize the rest of the AppleAcceleratorTable interface and move it
/// to this class.
```
I suspect a lot of these helper functions created also apply to DWARF 5's
accelerator table, so they could be moved to the base class.
The changes above also expose a bug in this implementation: the previous
algorithm looks at _one_ string inside the bucket, but never bothers checking
for collisions. When the main search loop is written as it is with this patch,
the problem becomes evident. We do not fix the issue in this patch, as it is
intended to be NFC.

[OpenMP] Fix using the target ID when using the new driver
AMDGPU sometimes uses a novel formatting for their offloading
architecture called the target id. This merges the attributes and the
architecture name into a single string. Previously, we were passing this
as the canonical architecture name. This caused the linker wrapper to
fail to find relevant libraries and then pass an incalid CPU name. This
patch changes the handling in the offload packager to handle the
canonical architecture and then extract the features.

[lldb] Disable variable watchpoints when going out of scope
If we use a variable watchpoint with a condition using a scope variable,
if we go out-of-scope, the watpoint remains active which can the
expression evaluator to fail to parse the watchpoint condition (because
of the missing varible bindings).
This was discovered after `watchpoint_callback.test` started failing on
the green dragon bot.
This patch should address that issue by setting an internal breakpoint
on the return addresss of the current frame when creating a variable
watchpoint. The breakpoint has a callback that will disable the watchpoint
if the the breakpoint execution context matches the watchpoint execution
context.
This is only enabled for local variables.
This patch also re-enables the failing test following
