Martin Storsjö f5e2ea9a43 [AArch64] Add asm directives for the remaining SEH unwind codes
Add support in llvm-readobj for displaying them and support in the
asm parsser, AArch64TargetStreamer and MCWin64EH for emitting them.

The directives for the remaining basic opcodes have names that
match the opcode in the documentation.

The directives for custom stack cases, that are named
MSFT_OP_TRAP_FRAME, MSFT_OP_MACHINE_FRAME, MSFT_OP_CONTEXT
and MSFT_OP_CLEAR_UNWOUND_TO_CALL, are given matching assembler
directive names that fit into the rest of the opcode naming;
.seh_trap_frame, .seh_context, .seh_clear_unwound_to_call

The opcode MSFT_OP_MACHINE_FRAME is mapped to the existing
opecode enum UOP_PushMachFrame that is used on x86_64, and also
uses the corresponding existing x86_64 directive name
.seh_pushframe.

Raphael Isemann 9124fa5920 Fix broken HUGE_VALF macro in llvm-c/DataTypes.h
Commit 3a29393b47 removes the cmath/math.h
includes from the DataTypes.h header to speed up parsing. However the
DataTypes.h header was using this header to get the macro `HUGE_VAL` for its own
`HUGE_VALF` macro definition. Now the macro instead just expands into a plain
`HUGE_VAL` token which leads to compiler errors unless `math.h` was previously
included by the including source file. It also leads to compiler warnings with
enabled module builds which point out this inconsistency.

The correct way to fix this seems to be to just remove HUGE_VALF from the
header. llvm-c is not referencing that macro from what I can see and users
probably should just include the math headers if they need it (or define it on
their own for really old C versions).

Raphael Isemann f0699d9109 [debugserver] Fix that debugserver's stop reply packets always return signal code 0
If our process terminates due to an unhandled signal, we are supposed to get the
signal code via WTERMSIG. However, we instead try to get the exit status via
WEXITSTATUS which just ends up always calculating signal code 0 (at least on the
macOS implementation where it just shifts the signal code bits away and we're
left with only 0 bits).

The exit status calculation on the LLDB side also seems a bit off as it claims
an exit status that is just the signal code (instead of for example 128 + signal
code), but that will be another patch.

Jakub Lichman 8d35080ebb [mlir][Linalg] Wrong tile size for convolutions fixed
Sizes of tiles (subviews) are bigger by 1 than they should. Let's consider
1D convolution without batches or channels. Furthermore let m iterate over
the output and n over the kernel then input is accessed with m + n. In tiling
subview sizes for convolutions are computed by applying requested tile size
together with kernel size to the above mentioned expression thus let's say
for tile size of 2 the subview size is 2 + size(n), which is bigger by one
than it should since we move kernel only once. The problem behind it is that
range is not turned into closed interval before the composition. This commit
fixes the problem by turning ranges first into closed intervals by substracting
1 and after the composition back to half open by adding 1.

- makes report_bad_alloc_error to print the failure reason passed

- fixes the documentation to indicate that report_bad_alloc_error

- uses a consistent name for the size/capacity argument to `grow`

Hongtao Yu f09ccf89fb [ThinLTO] Fix a metadata lost issue with DICompileUnit import.
For ThinLTO importing we don't need to import all the fields of the DICompileUnit, such as enums, macros, retained types lists. The importation of those fields were previously disabled by setting their value map entries to nullptr. Unfortunately a metadata node can be shared by multiple metadata operands. Setting the map entry to nullptr might result in not importing other metadata unexpectedly.  The issue is fixed by explicitly setting the original DICompileUnit fields (still a copy of the source module metadata) to null.

Adrian Prantl 272742a92d Perform an extra consistency check when searching ModuleManager's
cache for implicit modules.

The ModuleManager's use of FileEntry nodes as the keys for its map of
loaded modules is less than ideal. Uniqueness for FileEntry nodes is
maintained by FileManager, which in turn uses inode numbers on hosts
that support that. When coupled with the module cache's proclivity for
turning over and deleting stale PCMs, this means entries for different
module files can wind up reusing the same underlying inode. When this
happens, subsequent accesses to the Modules map will disagree on the
ModuleFile associated with a given file.

In general, it is not sufficient to resolve this conundrum with a type
like FileEntryRef that stores the name of the FileEntry node on first
access because of path canonicalization issues. However, the paths
constructed for implicit module builds are fully under Clang's
control. We *can*, therefore, rely on their structure being consistent
across operating systems and across subsequent accesses to the Modules
map.

To mitigate the effects of inode reuse, perform an extra name check when
implicit modules are returned from the cache. This has the effect of
forcing reused FileEntry nodes to stomp over existing-but-stale entries
in the cache, which simulates a miss - exactly the desired behavior.
