We are only adding this in `flang` - the bash wrapper script for the

`flang-new` (i.e. the actual driver).

Define an API for, and implement, runtime support for arbitrary
assignment of one descriptor's data to another, with full support for
(re)allocation of allocatables with finalization when necessary,
user-defined derived type assignment TBP calls, and intrinsic (default)
componentwise assignment of derived type instances with allocation of
automatic components. Also clean up API and implementation of
finalization/destruction using knowledge gained while studying
edge cases for assignment in the 2018 standard.
The look-up procedure for special procedure bindings in derived
types has been optimized from O(N) to O(1) since it will probably
matter more. This required some analysis in runtime derived type
description table construction in semantics and some changes to the
table schemata.
Executable Fortran tests have been developed; they'll be added
to the test base once they can be lowered and run by f18.

This reverts commit 3229c971512404c512e041c3e88f22dbec2b650b.
With a2acac6 in place this should provide enough info to work out
any repeat of the failure in cross_ovver_uniform_dist.test.
This patch is a revert of e08f205f5c2c. In that patch, DW_TAG_subprograms
were permitted to be referenced across CU boundaries, to improve stack
trace construction using call site information. Unfortunately, as
documented in PR48790, the way that subprograms are "owned" by dwarf units
is sufficiently complicated that subprograms end up in unexpected units,
invalidating cross-unit references.
There's no obvious way to easily fix this, and several attempts have
failed. Revert this to ensure correct DWARF is always emitted.
Three tests change in addition to the reversion, but they're all very
light alterations.

When going through the CU entries in the name index,
make sure to compare the name entry's CU
offset against the skeleton CU's offset.
Previously there would be a mismatch, since the
wrong offset was compared, and thus no suitable

Use hexadecimal numbers rather than decimal in various vFile packets
in order to fix compatibility with gdbserver. This also changes the few
custom LLDB packets -- while technically they do not have to be changed,
it is easier to use the same syntax consistently across LLDB.

Sync the mode constants used to drive vFile:open requests with these
used by GDB and defined for the gdb remote protocol. This makes it
possible to use 'platform file open' after connecting to gdbremote
server (and to some degree to operate on the open file modulo other
incompatibilities).

Modify OpenOptions enum to open the future path into synchronizing
vFile:open bits with GDB. Currently, LLDB and GDB use different flag
models effectively making it impossible to match bits. Notably, LLDB
uses two bits to indicate read and write status, and uses union of both
for read/write. GDB uses a value of 0 for read-only, 1 for write-only
and 2 for read/write.
In order to future-proof the code for the GDB variant:
1. Add a distinct eOpenOptionReadWrite constant to be used instead
of (eOpenOptionRead | eOpenOptionWrite) when R/W access is required.
2. Rename eOpenOptionRead and eOpenOptionWrite to eOpenOptionReadOnly
and eOpenOptionWriteOnly respectively, to make it clear that they
do not mean to be combined and require update to all call sites.
3. Use the intersection of all three flags when matching against
the three possible values.
This commit does not change the actual bits used by LLDB.

Shuffles which are broken into separate halves reveal splats in which
a half is accessed via one index; such operations can be optimized to
use "vrgather.vi".
This optimization could be achieved by adding extra patterns to match
`vrgather_vv_vl` which uses a splat as an index operand, but this patch
instead identifies splat earlier. This way, future optimizations can
build on top of the data gathered here, e.g., to splat-gather dominant
indices and insert any leftovers.

The patch removes mutable accessor methods for sections and segments.
As for now, const variants of them are not used because all callers have
mutable access to an instance of Object. On the other hand, they do not
actually modify the sets, so it looks better to keep only const ones.

54902e00d1280785042e2c7ec71b25a949ade92c added a use of
/alternatename via a #pragma comment(linker); in MinGW mode, this
requires building with -fms-extensions. (This flag is added to
SANITIZER_COMMON_CFLAGS in the toplevel CMakeLists.txt.)
This avoids a warning when building in MinGW mode (about an unknown

In MSVC mode, CMake provides CMAKE_C_COMPILER_ARCHITECTURE_ID,
which should be accurate for what the compiler produces. Keep
the old CMAKE_C_SIZEOF_VOID_P based fallback in case this
doesn't provide matches.
In GCC/MinGW mode, CMake doesn't provide that. As we're trying to

estimate whether it's x86/x86_64/arm/aarch64.

This test didn't include all test check lines, thanks to .'s in function
names. It also changed the triple to hard float to make a more
interesting test for NEON code generation.
And assign RegClass (i.e. operand class for all GPR) as the super class
of ARegClass and DRegClass. Note that this is a NFC change because
actually we already had XRDReg to model either address or data register
operands (as well as test coverage for it). The new super class syntax
added here is just making the relations between three RegClass-es more
explicit.
The decoder function and table are the same as FPR128, use that instead.
