CallSite will likely be removed soon, but AbstractCallSite serves a different purpose and won't be going away.
This patch switches it to internally store a CallBase* instead of a
CallSite. The only interface changes are the removal of the getCallSite
method and getCallBackUses now takes a CallBase&. These methods had only
a few callers that were easy enough to update without needing a
compatibility shim.
In the future once the other CallSites are gone, the CallSite.h

This removes the conditional layout of relocation_info bitfields that was
introduced in 3ccd677bf (svn r358839). The platform relocation_info
struct (defined in usr/include/mach-o/reloc.h) does not define the layout of
this struct differently on big-endian platforms and we want to keep the LLVM
and platform definitions in sync.
To fix the bug that 3ccd677bf addressed this patch modifies JITLink to construct
its relocation_info structs from the raw relocation words using shift and mask
operations.
Currently, `--dump-input` implies that all `--implicit-check-not`
patterns appear on line 1 by printing annotations like:
```
1: foo bar baz
not:1 !~~ error: no match expected
```
This patch changes that to:
```
1: foo bar baz
not:imp1 !~~ error: no match expected
```
`imp1` indicates the first `--implicit-check-not` pattern.

Ensure that symbols explicitly* assigned a section name are placed into
a section with a compatible entry size.
This is done by creating multiple sections with the same name** if
incompatible symbols are explicitly given the name of an incompatible
section, whilst:
- Avoiding using uniqued sections where possible (for readability and
to maximize compatibly with assemblers).
- Creating as few SHF_MERGE sections as possible (for efficiency).
Given that each symbol is assigned to a section in a single pass, we
must decide which section each symbol is assigned to without seeing the
properties of all symbols. A stable and easy to understand assignment is
desirable. The following rules facilitate this: The "generic" section
for a given section name will be mergeable if the name is a mergeable
"default" section name (such as .debug_str), a mergeable "implicit"
section name (such as .rodata.str2.2), or MC has already created a
mergeable "generic" section for the given section name (e.g. in response
to a section directive in inline assembly). Otherwise, the "generic"
section for a given name is non-mergeable; and, non-mergeable symbols
are assigned to the "generic" section, while mergeable symbols are
assigned to uniqued sections.
Terminology:
"default" sections are those always created by MC initially, e.g. .text
or .debug_str.
"implicit" sections are those created normally by MC in response to the
symbols that it encounters, i.e. in the absence of an explicit section
name assignment on the symbol, e.g. a function foo might be placed into
a .text.foo section.
"generic" sections are those that are referred to when a unique section
ID is not supplied, e.g. if there are multiple unique .bob sections then
".quad .bob" will reference the generic .bob section. Typically, the
generic section is just the first section of a given name to be created.
Default sections are always generic.
* Typically, section names might be explicitly assigned in source code
using a language extension e.g. a section attribute: _attribute_
((section ("section-name"))) -
https://clang.llvm.org/docs/AttributeReference.html
** I refer to such sections as unique/uniqued sections. In assembly the
", unique," assembly syntax is used to express such sections.
Fixes https://bugs.llvm.org/show_bug.cgi?id=43457.
See https://reviews.llvm.org/D68101 for previous discussions leading to
this patch.
Some minor fixes were required to LLVM's tests, for tests had been using
the old behavior - which allowed for explicitly assigning globals with
incompatible entry sizes to a section.
This fix relies on the ",unique ," assembly feature. This feature is not
available until bintuils version 2.35
(https://sourceware.org/bugzilla/show_bug.cgi?id=25380). If the
integrated assembler is not being used then we avoid using this feature
for compatibility and instead try to place mergeable symbols into
non-mergeable sections or issue an error otherwise.

Summary:
This verifier tries to ensure that DebugLoc's don't just disappear as
we transform the MIR. It observes the instructions created, erased, and
changed and at checkpoints chosen by the client algorithm verifies the
locations affected by those changes.
In particular, it verifies that:
* Every DebugLoc for an erased/changing instruction is still present on
at least one new/changed instruction
* Failing that, that there is a line-0 location in the new/changed
instructions. It's not possible to confirm which locations were merged so
it conservatively assumes all unaccounted for locations are accounted
for by any line-0 location to avoid false positives.
If that fails, it prints the lost locations in the debug output along with
the instructions that should have accounted for them.
In theory, this is usable by the legalizer, combiner, selector and any other
pass that performs incremental changes to the MIR. However, it has so far
only really been tested on the legalizer (not including the artifact
combiner) where it has caught lots of lost locations, particularly in Custom
legalizations. There's only one example here as my initial testing was on an
out-of-tree target and I haven't done a pass over the in-tree targets yet.

The AAMap.lookup() call created a temporary value if the key was not
present. Since the value was another map it was not free to create it.
Instead of a lookup we now use find and compare the result against the
end iterator explicitly. The result is the same but we never need to
create a temporary map.
Since we use the fact that some uses are droppable in the Attributor we
need to handle them explicitly when we replace uses. As an example, an
assumed dead value can have live droppable users. In those we cannot
replace the value simply by an undef. Instead, we either drop the uses
(via `dropDroppableUses`) or keep them as they are. In this patch we do
both, depending on the situation. For values that are dead but not
necessarily removed we keep droppable uses around because they contain
information we might be able to use later. For values that are removed
we drop droppable uses explicitly to avoid replacement with undef.
For `.bss; nop`, MC inappropriately calls abort() (via report_fatal_error()) with a message
`cannot have fixups in virtual section!`
It is a bug to crash for invalid user input. Fix it by erroring out early in EmitInstToData().
Similarly, emitIntValue() in a virtual section (SHT_NOBITS in ELF) can crash with the mssage
`non-zero initializer found in section '.bss'` (see D4199)
It'd be nice to report the location but so many directives can call emitIntValue()
and it is difficult to track every location.
Note, COFF does not crash because MCAssembler::writeSectionData() is not
called for an IMAGE_SCN_CNT_UNINITIALIZED_DATA section.
Note, GNU as' arm64 backend reports ``Error: attempt to store non-zero value in section `.bss'``
for a non-zero .inst but fails to do so for other instructions.
We simply reject all instructions, even if the encoding is all zeros.

Before, we eagerly analyzed all the functions to collect information
about them, e.g. what instructions may read/write memory. This had
multiple drawbacks:
- In CGSCC-mode we can end up looking at a callee which is not in the
SCC but for which we need an initialized cache.
- We end up looking at functions that we deem dead and never need to
analyze in the first place.
- We have a implicit dependence which is easy to break.
This patch moves the function analysis into the information cache and
makes it lazy. There is no real functional change expected except due to
the first reason above.

Summary:
While it is uncommon that the ExternalCallingNode needs to be updated,
it can happen. It is uncommon because most functions listed as callees
have external linkage, modifying them is usually not allowed. That said,
there are also internal functions that have, or better had, their
"address taken" at construction time. We conservatively assume various
uses cause the address "to be taken". Furthermore, the user might have
become dead at some point. As a consequence, transformations, e.g., the
Attributor, might be able to replace a function that is listed
as callee of the ExternalCallingNode.
Since there is no function corresponding to the ExternalCallingNode, we
did just remove the node from the callee list if we replaced it (so
far). Now it would be preferable to replace it if needed and remove it
otherwise. However, removing the node has implications on the CGSCC
iteration. Locally, that caused some other nodes to be never visited
but it is for sure possible other (bad) side effects can occur. As it
seems conservatively safe to keep the new node in the callee list we
will do that for now.

the end of the type, while this combine assumes that the casted bits
appear between meaningful bits.
This also uncovered a segmentation fault in the AMDGPU
InstructionSelector. The tests triggering this bug have been moved to
their own file and a check for the segmentation fault has been added.

Summary:
No error or warning is emitted when specific reserved registers are
written to in inline assembly. Therefore, writes to the program counter
or to the frame pointer, for instance, were permitted, which could have
led to undesirable behaviour.
Example:
int foo() {
register int a __asm__("r7"); // r7 = frame-pointer in M-class ARM
__asm__ __volatile__("mov %0, r1" : "=r"(a) : : );
return a;
}
In contrast, GCC issues an error in the same scenario.
This patch detects writes to specific reserved registers in inline
assembly for ARM and emits an error in such case. The detection works
for output and input operands. Clobber operands are not handled here:
they are already covered at a later point in
AsmPrinter::emitInlineAsm(const MachineInstr *MI). The registers
covered are: program counter, frame pointer and base pointer.
This is ARM only. Therefore the implementation of other targets'
counterparts remain open to do.

Summary:
Currently, the internal options -vectorize-loops, -vectorize-slp, and
-interleave-loops do not have much practical effect. This is because
they are used to initialize the corresponding flags in the pass
managers, and those flags are then unconditionally overwritten when
compiling via clang or via LTO from the linkers. The only exception was
-vectorize-loops via opt because of some special hackery there.
While vectorization could still be disabled when compiling via clang,
using -fno-[slp-]vectorize, this meant that there was no way to disable
it when compiling in LTO mode via the linkers. This only affected
ThinLTO, since for regular LTO vectorization is done during the compile
step for scalability reasons. For ThinLTO it is invoked in the LTO
backends. See also the discussion on PR45434.
This patch makes it so the internal options can actually be used to
disable these optimizations. Ultimately, the best long term solution is
to mark the loops with metadata (similar to the approach used to fix
-fno-unroll-loops in D77058), but this enables a shorter term
workaround, and actually makes these internal options useful.
I constant propagated the initial values of these internal flags into
the pass manager flags (for some reasons vectorize-loops and
interleave-loops were initialized to true, while vectorize-slp was
initialized to false). As mentioned above, they are overwritten
unconditionally so this doesn't have any real impact, and these initial
values aren't particularly meaningful.
I then changed the passes to check the internl values and return without
performing the associated optimization when false (I changed the default
of -vectorize-slp to true so the options behave similarly). I was able
to remove the hackery in opt used to get -vectorize-loops=false to work,
as well as a special option there used to disable SLP vectorization.
Finally, I changed thinlto-slp-vectorize-pm.c to:
a) Only test SLP (moved the loop vectorization checking to a new test).
b) Use code that is slp vectorized when it is enabled, and check that
instead of whether the pass is enabled.
c) Test the new behavior of -vectorize-slp.
d) Test both pass managers.
The loop vectorization (and associated interleaving) testing I moved to
a new thinlto-loop-vectorize-pm.c test, with several changes:
a) Changed the flags on the interleaving testing so that it will
actually interleave, and check that.
b) Test the new behavior of -vectorize-loops and -interleave-loops.
c) Test both pass managers.
