23 months ago[LTO] Make local linkage GlobalValue in non-prevailing COMDAT available_externally
Fangrui Song [Fri, 11 Nov 2022 05:54:43 +0000 (21:54 -0800)]
[LTO] Make local linkage GlobalValue in non-prevailing COMDAT available_externally

For a local linkage GlobalObject in a non-prevailing COMDAT, it remains defined while its
leader has been made available_externally. This violates the COMDAT rule that
its members must be retained or discarded as a unit.

To fix this, update the regular LTO change D34803 to track local linkage
GlobalValues, and port the code to ThinLTO (GlobalAliases are not handled.)

This fixes two problems.

(a) `__cxx_global_var_init` in a non-prevailing COMDAT group used to
linger around (unreferenced, hence benign), and is now correctly discarded.
```
int foo();
inline int v = foo();
```

(b) Fix https://github.com/llvm/llvm-project/issues/58215:
as a size optimization, we place private `__profd_` in a COMDAT with a
`__profc_` key. When FuncImport.cpp makes `__profc_` available_externally due to
a non-prevailing COMDAT, `__profd_` incorrectly remains private. This change
makes the `__profd_` available_externally.

```
cat > c.h <<'eof'
extern void bar();
inline __attribute__((noinline)) void foo() {}
eof
cat > m1.cc <<'eof'
#include "c.h"
int main() {
  bar();
  foo();
}
eof
cat > m2.cc <<'eof'
#include "c.h"
__attribute__((noinline)) void bar() {
  foo();
}
eof

clang -O2 -fprofile-generate=./t m1.cc m2.cc -flto -fuse-ld=lld -o t_gen
rm -fr t && ./t_gen && llvm-profdata show -function=foo t/default_*.profraw

clang -O2 -fprofile-generate=./t m1.cc m2.cc -flto=thin -fuse-ld=lld -o t_gen
rm -fr t && ./t_gen && llvm-profdata show -function=foo t/default_*.profraw
```

If a GlobalAlias references a GlobalValue which is just changed to
available_externally, change the GlobalAlias as well (e.g. C5/D5 comdats due to
cc1 -mconstructor-aliases). The GlobalAlias may be referenced by other
available_externally functions, so it cannot easily be removed.

Depends on D137441: we use available_externally to mark a GlobalAlias in a
non-prevailing COMDAT, similar to how we handle GlobalVariable/Function.
GlobalAlias may refer to a ConstantExpr, not changing GlobalAlias to
GlobalVariable gives flexibility for future extensions (the use case is niche.
For simplicity we don't handle it yet). In addition, available_externally
GlobalAlias is the most straightforward implementation and retains the aliasee
information to help optimizers.

See windows-vftable.ll: Windows vftable uses an alias pointing to a
private constant where the alias is the COMDAT leader. The COMDAT use case
is skeptical and ThinLTO does not discard the alias in the non-prevailing COMDAT.
This patch retains the behavior.

[lldb][test] TestConstStaticIntegralMember.py: fix for clang-{9,11,13}

**Summary**

The public lldb matrix bot is failing for tests compiled with clang-9, clang-11, clang-13.

This patch addresses these failures by evaluating the enum case that
doesn't cause malformed DWARF in older version of clang.

There was no particular reason we had to use `true` enum case
to reproduce the bug in #58383, so simply switch to use `false`
to get all bots passing again.

**Details**

In older versions of clang, the following snippet:
```
enum EnumBool : bool {
  enum_bool_case1 = false,
  enum_bool_case2 = true,
};

struct A {
  const static EnumBool enum_bool_val = enum_bool_case2;
};
```

…results in following DWARF:
```
0x00000052:   DW_TAG_structure_type
                DW_AT_calling_convention        (DW_CC_pass_by_value)
                DW_AT_name      ("A")
                DW_AT_byte_size (0x01)
                DW_AT_decl_file ("/Users/michaelbuch/Git/llvm-project/lldb/test/API/lang/cpp/const_static_integral_member/repro.cpp")
                DW_AT_decl_line (6)

0x0000005b:     DW_TAG_member
                  DW_AT_name    ("enum_bool_val")
                  DW_AT_type    (0x0000000000000068 "const EnumBool")
                  DW_AT_decl_file       ("/Users/michaelbuch/Git/llvm-project/lldb/test/API/lang/cpp/const_static_integral_member/repro.cpp")
                  DW_AT_decl_line       (7)
                  DW_AT_external        (true)
                  DW_AT_declaration     (true)
                  DW_AT_const_value     (-1)

```

Note the `DW_AT_const_value == -1`

When evaluating `A::enum_bool_val` in the lldb we get:
```
(lldb) p A::enum_bool_val
error: expression failed to parse:
error: Couldn't lookup symbols:
  __ZN1A13enum_bool_valE
```

Enabling the DWARF logs we see:

```
(arm64) clang-13.out: DWARFASTParserClang::ParseTypeFromDWARF (die = 0x00000068, decl_ctx = 0x136ac1e30 (die 0x0000000b)) DW_TAG_const_type name = '(null)')
Failed to add const value to variable A::enum_bool_val: Can't store unsigned value 18446744073709551615 in integer with 1 bits.
```

This occurs because a boolean enum is considered an unsigned integer
type, but we try to initialize it with a `-1`.

**Testing**

- Confirmed locally that top-of-tree lldb correctly
  evaluates the previously failing expression when
  the test program is compiled with clang-13

it removes a shuffle, and the backend can already narrow

This patch adds the -fpass-plugin option to flang which dynamically loads LLVM

of the option is designed to replicate that of the same option in clang and
thus has the same capabilities and limitations.

Features:

  Multiple instances of -fpass-plugin=path-to-file can be specified and each
  of the files will be loaded in that order.

  The flag can be passed to both flang-new and flang-new -fc1.

  The flag will be listed when the -help flag is passed to both flang-new and
  flang-new -fc1. It will also be listed when the --help-hidden flag is passed.

Limitations:

  Dynamically loaded plugins are not supported in clang on Windows and are not
  supported in flang either.

Addenda:

  Some minor stylistic changes are made in the files that were modified to
  enable this functionality. Those changes make the naming of functions more
  consistent, but do not change any functionality that is not directly

register class can be used in the pattern template, and the hard-coding
of mutual coping of `CFR` and `GRP` is eliminated, reducing redundant
