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.

[AArch64] Allow users-facing feature names in clang target attributes

D133848 added support for the GCC format of target("..") attributes. The
supported formats to match gcc are:
//  "arch=<arch>" - parsed to features as per -march=..
//  "cpu=<cpu>" - parsed to features as per -mcpu=.., with CPU set to <cpu>
//  "tune=<cpu>" - TuneCPU set to <cpu>
//  "+feature", "+nofeature" - Add (or remove) feature.

We also support the existing formats, previously accepted by clang, for
compatibility with the existing code and intrinsics code:
//  "feature", "no-feature" - Add (or remove) feature.

The clang formats would accept and use internal feature names
("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)."

isValidFeatureName in clang is present).

The Assignment Tracking debug-info feature is outlined in this RFC:

https://discourse.llvm.org/t/
rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir

Overview
It's possible to find intrinsics linked to an instruction by looking at the
MetadataAsValue uses of the attached DIAssignID. That covers instruction ->
intrinsic(s) lookup. Add a global DIAssignID -> instruction(s) map which gives
us the ability to perform intrinsic -> instruction(s) lookup. Add plumbing to
keep the map up to date through optimisations and add utility functions
including two that perform those lookups. Finally, add a unittest.

Details
In llvm/lib/IR/LLVMContextImpl.h add AssignmentIDToInstrs which maps DIAssignID
* attachments to Instruction *s. Because the DIAssignID * is the key we can't
use a TrackingMDNodeRef for it, and therefore cannot easily update the mapping
when a temporary DIAssignID is replaced.

Temporary DIAssignID's are only used in IR parsing to deal with metadata
forward references. Update llvm/lib/AsmParser/LLParser.cpp to avoid using
temporary DIAssignID's for attachments.

In llvm/lib/IR/Metadata.cpp add Instruction::updateDIAssignIDMapping which is
called to remove or add an entry (or both) to AssignmentIDToInstrs. Call this
from Instruction::setMetadata and add a call to setMetadata in Intruction's
dtor that explicitly unsets the DIAssignID so that the mappging gets updated.

In llvm/lib/IR/DebugInfo.cpp and DebugInfo.h add utility functions:

    getAssignmentInsts(const DbgAssignIntrinsic *DAI)
    getAssignmentMarkers(const Instruction *Inst)
    RAUW(DIAssignID *Old, DIAssignID *New)
    deleteAll(Function *F)
    deleteAssignmentMarkers(const Instruction *Inst)

These core utils are tested in llvm/unittests/IR/DebugInfoTest.cpp.

[Statepoint] Use default attributes for some GC intrinsics

This adds the default intrinsic attributes (nosync, nofree, nocallback,
willreturn) to the gc.result, gc.relocate, gc.pointer.base and
gc.pointer.offset intrinsics. As far as I understand, all of these
are supposed to be pure. Some quotes from LangRef:

> A gc.result is modeled as a ‘readnone’ pure function. It has no
> side effects since it is just a projection of the return value of
> the previous call represented by the gc.statepoint.

> A gc.relocate is modeled as a readnone pure function. It has no
> side effects since it is just a way to extract information about
> work done during the actual call modeled by the gc.statepoint.

Having willreturn in particular will be important to avoid
optimization regressions in the future.
