[Host] Return the user's shell from GetDefaultShell
LLDB handles shell expansion by running lldb-argdumper under a shell.
Currently, this is always /bin/sh on POSIX. This potentially leads to
different behavior between lldb and the user's current shell. Here's an
example of different expansions between shells:
$ /bin/bash -c 'echo -config={Options:[{key:foo_key,value:foo_value}]}'
-config={Options:[key:foo_key]} -config={Options:[value:foo_value]}
$ /bin/zsh -c 'echo -config={Options:[{key:foo_key,value:foo_value}]}'

-config={Options:[key:foo_key]} -config={Options:[value:foo_value]}
$ /bin/fish -c 'echo -config={Options:[{key:foo_key,value:foo_value}]}'
-config=Options:[key:foo_key] -config=Options:[value:foo_value]
To reduce surprises, this patch returns the user's current shell. It
first looks at the SHELL environment variable. If that isn't set, it'll
ask for the user's default shell. Only if that fails, we'll fallback to
/bin/sh, which should always be available.

AMDGPU/SILoadStoreOptimizer: Optimize scanning for mergeable instructions
Summary:
This adds a pre-pass to this optimization that scans through the basic
block and generates lists of mergeable instructions with one list per unique
address.
In the optimization phase instead of scanning through the basic block for mergeable
instructions, we now iterate over the lists generated by the pre-pass.
The decision to re-optimize a block is now made per list, so if we fail to merge any
instructions with the same address, then we do not attempt to optimize them in
future passes over the block. This will help to reduce the time this pass
spends re-optimizing instructions.
In one pathological test case, this change reduces the time spent in the
SILoadStoreOptimizer from 0.2s to 0.03s.
This restructuring will also make it possible to implement further solutions in
this pass, because we can now add less expensive checks to the pre-pass and
filter instructions out early which will avoid the need to do the expensive
scanning during the optimization pass. For example, checking for adjacent
offsets is an inexpensive test we can move to the pre-pass.

This patch reimplements command line option parsing in dsymutil with
Tablegen and libOption. The main motivation for this change is to
prevent clashes with other cl::opt options defined in llvm. Although
it's a bit more heavyweight, it has some nice advantages such as no
global static initializers and better separation between the code and
the option definitions.
I also used this opportunity to improve how dsymutil deals with
incompatible options. Instead of having checks spread across the code,
everything is now grouped together in verifyOptions. The fact that the
options are no longer global means that we need to pass them around a
bit more, but I think it's worth the trade-off.

[BPF] Handle offset reloc endpoint ending in the middle of chain properly
During studying support for bitfield, I found an issue for
an example like the one in test offset-reloc-middle-chain.ll.
struct t1 { int c; };
struct s1 { struct t1 b; };
struct r1 { struct s1 a; };
#define _(x) __builtin_preserve_access_index(x)
void test1(void *p1, void *p2, void *p3);
void test(struct r1 *arg) {
struct s1 *ps = _(&arg->a);
struct t1 *pt = _(&arg->a.b);
int *pi = _(&arg->a.b.c);
test1(ps, pt, pi);
}
The IR looks like:
%0 = llvm.preserve.struct.access(base, ...)
%1 = llvm.preserve.struct.access(%0, ...)
%2 = llvm.preserve.struct.access(%1, ...)
using %0, %1 and %2
In this case, we need to generate three relocatiions
corresponding to chains: (%0), (%0, %1) and (%0, %1, %2).
After collecting all the chains, the current implementation
process each chain (in a map) with code generation sequentially.
For example, after (%0) is processed, the code may look like:
%0 = base + special_global_variable
// llvm.preserve.struct.access(base, ...) is delisted
// from the instruction stream.
%1 = llvm.preserve.struct.access(%0, ...)
%2 = llvm.preserve.struct.access(%1, ...)
using %0, %1 and %2
When processing chain (%0, %1), the current implementation
tries to visit intrinsic llvm.preserve.struct.access(base, ...)
to get some of its properties and this caused segfault.
This patch fixed the issue by remembering all necessary
information (kind, metadata, access_index, base) during
analysis phase, so in code generation phase there is
no need to examine the intrinsic call instructions.
This also simplifies the code.

[libc++abi] Do not export some implementation-detail functions
Summary:
Those functions started being mistakenly exported from the libc++abi
shared library after commit r344152 in 2018. Removing these symbols is
technically an ABI break. However, they are not part of the C++ ABI,
they haven't ever been re-exported from libc++, and they are not
declared in any public header, so it's very unlikely that calls to
these functions exist out there. Also, the functions have reserved
names, so any impacted user would have to have tried really hard
being broken by this removal.
Note that avoiding this kind of problem is exactly why we're now
controlling exported symbols explicitly with a textual list.
Also note that applying the hidden visibility attribute is necessary
because the list of exported symbols is only used on Apple platforms
for the time being.

[AArch64] Static (de)allocation of SVE stack objects.
Adds support to AArch64FrameLowering to allocate fixed-stack SVE objects.
The focus of this patch is purely to allow the stack frame to
allocate/deallocate space for scalable SVE objects. More dynamic
allocation (at compile-time, i.e. determining placement of SVE objects
on the stack), or resolving frame-index references that include
scalable-sized offsets, are left for subsequent patches.
SVE objects are allocated in the stack frame as a separate region below
the callee-save area, and above the alignment gap. This is done so that
the SVE objects can be accessed directly from the FP at (runtime)
VL-based offsets to benefit from using the VL-scaled addressing modes.
The layout looks as follows:
+-------------+
| stack arg |
+-------------+
| Callee Saves|
| X29, X30 | (if available)
|-------------| <- FP (if available)
| : |
| SVE area |
| : |
+-------------+
|/////////////| alignment gap.
| : |
| Stack objs |
| : |
+-------------+ <- SP after call and frame-setup
SVE and non-SVE stack objects are distinguished using different
StackIDs. The offsets for objects with TargetStackID::SVEVector should be
interpreted as purely scalable offsets within their respective SVE region.

"Fix" TestFileHandle.py on non-darwin platforms
This test exposed a very long standing issue that the python file
objects returned by the FILE* typemap were unusable on non-darwin
platforms. The reason they work on darwin is that they rely on a
non-standard extension to fetch the "mode" of a FILE* object. On other
platforms, this code was #ifdefed out, and so we were returning an empty
mode.
As there's no portable way to get this information, I just change the
non-darwin path to return "r+", which should permit both reading and
writing operations on the object. If the underlying file descriptor
turns out to be incompatible with this mode, the operating system should
return EBADF (or equivalent), instead of the "file not open for XXX"
error from python.

Solution is to copy it always into a vgpr. This may result in a
subsequent copy into an agpr if that is what really needed, however
should not happen too often and likely will be folded later.
The opposite situation may not happen because an sgpr is always
illegal where agpr is legal, so such user instructions may not
