* move to host/target sections
stephentoub pushed a commit that referenced this pull request Jul 27, 2021
…et#53792)

I have expanded the PerfMap format produced by Crossgen2 and
R2RDump to produce metadata in form of pseudo-symbol records with
high addresses. In this version I have implemented four metadata
entries - output GUID, target OS, target architecture and perfmap
format version number.  I have verified for System.Private.CoreLib
and for the composite framework that Crossgen2 and R2RDump
produce identical metadata.

To facilitate a smooth transition to the new perfmap format, in
accordance with Juan's suggestion I have introduced a new command-line
option to explicitly specify the perfmap format revision. As of today,
0 corresponds to the legacy Crossgen1-style output where the
perfmap file name includes the {MVID} section, perfmap format #1
corresponds to current Crossgen2 with its new naming scheme.
As of today there are no differences in the file content.

Thanks

This adds support for EnC on arm64. A couple of notes on the
implementation compared to x64:
- On x64 we get the fixed stack size from unwind info. However, for the
  frames we set up on arm64 for EnC it is not possible to extract the
  frame size from there because their prologs generally look like

  stp fp, lr, [sp,#-16]!
  mov fp, sp
  sub sp, sp, dotnet#144

  with unwind codes like the following:

  set_fp; mov fp, sp

  save_fplr_x #1 (0x01); tp fp, lr, [sp, #-16]!

  As can be seen, it is not possible to get the fixed stack size from
  unwind info in this case. Instead we pass it through the GC info that
  already has a section for EnC data.

- On arm64 the JIT is required to place the PSPSym at the same offset
  from caller-SP for both the main function and for funclets. Due to
  this we try to allocate the PSPSym as early as possible in the main
  function and we must take some care in funclets.  However, this
  conflicts with the EnC frame header that the JIT uses to place values
  that must be preserved on EnC transitions. This is currently
  callee-saved registers and the MonitorAcquired boolean.

  Before this change we were allocating PSPSym above (before) the
  monitor acquired boolean, but we now have to allocate MonitorAcquired
  first, particularly because the size of the preserved header cannot
  change on EnC transitions, while the PSPSym can disappear or appear.
  This changes frame allocation slightly for synchronized functions.

These helpers are used to report names of things in warnings. The functional changes are:
* For method parameters, use the parameter name if available (and only if not fallback to the #1 notation)
* For property accessor methods, use the C# naming scheme, so for example Type.Property.get instead of Type.get_Property.

Both of these changes are in preparation to bring NativeAOT closer in behavior to ILLink and the trim analyzers.

For this I moved some of the helpers to the common shared code.

Some unrelated code cleanup as well.

The JitDump is unfinished because the compiler crashes when trying to dump the last line. Clearly, the `CNS_INT` is no longer a handle at that point because we just bashed it to a constant 1.

CodeQL flagged various places where we're dereferencing pointers that could be NULL, this PR systematically cleans some of them up via g_assert.
* g_assert result of g_build_path calls
* Allocation failure handling
* mono_class_inflate_generic_class_checked can return NULL

…#102133)

This generalizes the indir reordering optimization (that currently only
triggers for loads) to kick in for GT_STOREIND nodes.

The main complication with doing this is the fact that the data node of
the second indirection needs its own reordering with the previous
indirection. The existing logic works by reordering all nodes between
the first and second indirection that are unrelated to the second
indirection's computation to happen after it. Once that is done we know
that there are no uses of the first indirection's result between it and
the second indirection, so after doing the necessary interference checks
we can safely move the previous indirection to happen after the data
node of the second indirection.

Example:
```csharp
class Body { public double x, y, z, vx, vy, vz, mass; }

static void Advance(double dt, Body[] bodies)
{
    foreach (Body b in bodies)
    {
        b.x += dt * b.vx;
        b.y += dt * b.vy;
        b.z += dt * b.vz;
    }
}
```

* bug #1: don't allow for values out of the SerializationRecordType enum range

* bug #2: throw SerializationException rather than KeyNotFoundException when the referenced record is missing or it points to a record of different type

* bug #3: throw SerializationException rather than FormatException when it's being thrown by BinaryReader (or sth else that we use)

* bug #4: document the fact that IOException can be thrown

* bug #5: throw SerializationException rather than OverflowException when parsing the decimal fails

* bug #6: 0 and 17 are illegal values for PrimitiveType enum

* bug #7: throw SerializationException when a surrogate character is read (so far an ArgumentException was thrown)
