@daltenty's patch rG201ed14aea8c 
 should 
fix the problem. In the latest build 
http://lab.llvm.org:8011/builders/ppc64le-lld-multistage-test/builds/6813, 
`AIX.cpp.o` has been successfully generated. Thanks for letting us know.

I had the same doubt when I added it. There is definitely an alphabetical 
order, yet I found the distinction between Arch and OS took precedence. As we 
could see that the "n" in "Ananas" and "M" in "AMDGPU" would have both came 
before the "r" in "Arch" if they only followed alphabetical order. That said, 
we could still consider moving all three but that might be an unnecessary 
hassle, and having OS followed by Arch and back to OS seems a bit 
counter-intuitive after all.

Looks like this list is following alphabetical order here, which means we 
should probably put "ToolChains/AIX.cpp" right after "ToolChain.cpp".

Jason is right, I am fine with keeping `llvm_unreachable`.

Glad to know the build without assertion on would not be affected by this. I 
just have slight preference that we don't have this blank block in our product 
code when the assertion is off. Is that better we put this assertion before 
`if` block, and do something like this;

```
assert((Output.isFilename() || Output.isNothing()) && "Invalid output.");

if (Output.isFilename()) {
CmdArgs.push_back("-o");
CmdArgs.push_back(Output.getFilename());
  } 
```

Jason has provided a good point why `llvm_unreachable` was preferred here. 
Other than that, I believe the two are fairly interchangeable in this 
particular case. That said, I'm leaning towards keeping `llvm_unreachable`, but 
definitely add more comment if you have good reasons for using `assert`. Thanks!

As per my tests with assertion-off build, I found no side effect and/or 
unexpected behaviour caused by this. There was no warning or anything 
unexpected that would've not appeared when assertion is on.

The `crt0_r.o` has become a symlink to `crt0.o`, we don't need to add extra 
handling for it.

[PATCH] D68340: Add AIX toolchain and basic linker functionality

The name lookup rules should be sufficient to avoid needing so many using 
directives.

Try:
```
namespace aix = clang::driver::tools::aix;
using AIX = clang::driver::toolchains::AIX;

using namespace llvm::opt;
```

Add a period to the end of the sentence.

Agreed. It does not seem that the compiler (GCC or XL) passes `-e __start` 
explicitly. This block should be removed.

Add a comma after "i.e.".

For 32-bit mode, there is a "reentrant" variant for when `-pthread` or 
`-pthreads` is specified.



Comment at: clang/lib/Driver/ToolChains/AIX.cpp:81
+
+if (crt0)

This is always true. Maybe use a `getCrt0Basename` lambda?

See comment regarding `clang-format`.



Comment at: clang/lib/Driver/ToolChains/AIX.cpp:114
+

Use a trailing return type to make use of name lookup rules to find `Tool`:
```
auto AIX::buildLinker() const -> Tool * {
```



Comment at: clang/lib/Driver/ToolChains/AIX.h:19
+
+/// aix -- Directly call system default assembler and linker

This patch does not cover the assembler as the comment claims. Please add a 
TODO.



Comment at: clang/lib/Driver/ToolChains/AIX.h:35
+} // end namespace aix
+} // end namespace tools
+

I would suggest adding a blank line before closing `tools` and also closing the 
`driver` and `clang` namespaces here. Reopen the latter two in a block with the 
opening of `toolchains` below.



Comment at: clang/lib/Driver/ToolChains/AIX.h:42
+  AIX(const Driver , const llvm::Triple ,
+  const llvm::opt::ArgList );
+  ~AIX() override;

I believe `clang-format` would indent this so that the first character comes 
right after the position of the left parenthesis that opened the parameter list.



Comment at: clang/test/Driver/aix-ld.c:1
+// General tests that ld invocations on AIX targets sane. Note that we use

Add "are" before "sane".

+// sysroot to make these tests independent of the host system.
+
+// Check powerpc-ibm-aix7.1.0.0, 32-bit.

There seem to be no tests about `nostdlib`

IsArch64Bit used only in the assertion could cause warning when the assertion 
is turned off.

[PATCH] D68340: Add AIX toolchain and basic linker functionality

[Xiangling Liao via Phabricator via cfe-commits]

Xiangling_L added inline comments.



Comment at: clang/lib/Driver/ToolChains/AIX.cpp:38
+
+  if (!Args.hasArg(options::OPT_nostdlib)) {
+CmdArgs.push_back("-e");

Test with Clangtana on terran, when no '-nostdlib' specified, since '-e' & 
'__start' are the default behavior for AIX system linker, so there are no 
explicitly '-e' & '__start' found on linker input commanline, so I am wondering 
do we need to explicitly add them to 'CmdArgs'?



Comment at: clang/lib/Driver/ToolChains/AIX.cpp:47
+  else
+CmdArgs.push_back("-bso");
+

Ditto. Since by default, AIX linker is dynamically linked, '-bso' is implicitly 
set on AIX system linker when testing with Clangtana, so do we need to 
explicitly set '-bso' in LLVM?

+  // Only support 32 and 64 bit
+  if (!IsArch32Bit && !IsArch64Bit)
+llvm_unreachable("Unsupported bit width value");

Is there any reason to use llvm_unreachable here? I think we should use  
'assertion' instead here:

```
assert((IsArch32Bit || IsArch64Bit) && "...");
```



Comment at: clang/lib/Driver/ToolChains/AIX.cpp:54
+  } else {
+assert(Output.isNothing() && "Invalid output.");
+  }

I am not sure, if we compile with assertion off, does this extra 'else' {} have 
any side effect?



Comment at: clang/lib/Driver/ToolChains/AIX.cpp:70
+
+  if (!Args.hasArg(options::OPT_nostdlib)) {
+const char *crt0 = nullptr;

line 38 and line 70 use the same query, should they be put together? Or is 
there any exact order we should follow to push args into 'CmdArgs'?

An extra blank line preferred below.



Comment at: clang/lib/Driver/ToolChains/AIX.h:43
+  const llvm::opt::ArgList );
+  ~AIX() override;
+

Since we are not doing anything special in AIX toolchain destructor, seems like 
we don't need to override it?

Any reason we are testing library search path using libgcc.a? We could use any 
dummy path there, and upload a dummy archive library for the testing purpose.




Comment at: clang/lib/Driver/ToolChains/AIX.cpp:112

+AIX::~AIX() {}

We are not doing anything with the destructor. Do we need to declare and define 
it?
