Jim Ingham [Wed, 9 Nov 2022 18:11:16 +0000 (10:11 -0800)]
Handle aliasing a non-top-level command.

This didn't work previously because we had to check whether the incoming
command was an alias command, but if it wasn't we still used the result
of that lookup - which was by the command's node name.  That fails for
non-top-level commands.  In this case, the resolution is pretty simple since
we already have the node's CommandObject, so all we needed to do was turn
it into a shared pointer, for which I added enable_shared_from_this to the
CommandObject.

Don't try to create Expressions when the process is running.

We generally prohibit this at a higher level - for instance requiring
the process to be stopped for "expr".  But when we trigger an expression
for internal purposes (e.g. to fetch types from the ObjC runtime) we weren't
checking the process state.  Now we explicitly check this at the very start

The expand-atomicrmw-xchg-fp.ll seem to have used -O1 just to ensure
that the -atomic-expand pass were thinking that it wasn't running at
O0 level. Same thing can be ensured by using the -codegen-opt-level=1
option, making it possible to avoid using O1 in that test case.

In the vector-reductions-expanded.ll test case it was possible to
split the RUN line into using two opt invocations. First running
"opt -O2" using the new PM, and then running "opt -expand-reductions"
using the legacy PM.

Jez Ng [Tue, 8 Nov 2022 21:33:22 +0000 (16:33 -0500)]
[lld-macho] Overhaul map file code

The previous map file code left out was modeled after LLD-ELF's
implementation. However, ld64's map file differs quite a bit from
LLD-ELF's. I've revamped our map file implementation so it is better
able to emit ld64-style map files.

Notable differences:
* ld64 doesn't demangle symbols in map files, regardless of whether
  `-demangle` is passed. So we don't have to bother with
  `getSymbolStrings()`.
* ld64 doesn't emit symbols in cstring sections; it emits just the
  literal values. Moreover, it emits these literal values regardless of
  whether they are labeled with a symbol.
* ld64 emits map file entries for things that are not strictly symbols,
  such as unwind info, GOT entries, etc. That isn't handled in this
  diff, but this redesign makes them easy to implement.

Additionally, the previous implementation sorted the symbols so as to
emit them in address order. This was slow and unnecessary -- the symbols
can already be traversed in address order by walking the list of
OutputSections. This brings significant speedups. Here's the numbers
from the chromium_framework_less_dwarf benchmark on my Mac Pro, with the
`-map` argument added to the response file:

             base            diff           difference (95% CI)
  sys_time   2.922 ± 0.059   2.950 ± 0.085  [  -0.7% ..   +2.5%]
  user_time  11.464 ± 0.191  8.290 ± 0.123  [ -28.7% ..  -26.7%]
  wall_time  11.235 ± 0.175  9.184 ± 0.169  [ -19.3% ..  -17.2%]
  samples    16              23

(It's worth noting that map files are written in parallel with the
output binary, but they often took longer to write than the binary
itself.)

Finally, I did further cleanups to the map-file.s test -- there was no
real need to have a custom-named section. There were also alt_entry
symbol declarations that had no corresponding definition. Either way,
neither custom-named sections nor alt_entry symbols trigger special code
paths in our map file implementation.

("fullfp16"/"neon"/"sve") as opposed to the user facing names
("fp16"/"simd"/"sve"). Usually they use the same names, but can be
different for cases like fp, fullfp16 and mte (among others).

This patch makes the clang format also except the user facing names, by
parsing the features through getArchExtFeature. There is a fallback if
the name is not recognized (like "fullfp16"), where we add the existing
string which should then be checked later for consistency. This allows
the internal names to be used as before, so long as they are recognized
as internal names. (Note that we currently don't have an implementation
of isValidFeatureName. The backend will currently give an error like
"'-sid' is not a recognized feature for this target (ignoring feature)."
This should be improved in a later patch once an implementation of
isValidFeatureName in clang is present).
