M68k backend is not endian-safe

[awilfox]

I'm seeing the following output on a PPC64 (big endian) Power9 workstation when building and testing the latest release, 18.1.7:

Note that expected number 50402580 is 0x03011514 and actual number 353633025 is 0x15140301. The other 13 M68k-based tests fail in similar ways:

All of the noted tests fail back to 16.0.0, except MC/M68k/Control/bsr.s. The 15 branch only has two of these failures, with the rest still working. 14.0.6 passes all M68k tests.

15.0.0 results:

bisect found first bad commit

If llvm/llvm-project@b3de316420374536def0cc3bfb7d317db9fc830c is the first bad commit, I'm thinking DecodeImm32 is the buggy function on BE. I will dig further and see if I can reduce this further.

DecodeImm32 just wraps llvm.M68k.swapWord - so you should probably look in there:

https://github.com/llvm/llvm-project/blob/e5a41f0afc152cc24b8fef3aa177ef53b2e77c43/llvm/lib/Target/M68k/MCTargetDesc/M68kBaseInfo.h#L77-L94

@mshockwave any thoughts?

It feels like something is unconditionally byte-swapping regardless of the fact I'm on BE which is causing this corruption. Stubbing out swapWord (changing it to just return Val;) doesn't cause any change - as it shouldn't, since the comment (and the code) say it does nothing on a BE host.

The problem does not seem to be in DecodeImm32. The commit also changed the test files to be "correct", which is actually what caused the tests to start failing here. It seems to reason then that the M68k backend was always wrong on BE, it's just that the test suite wasn't checking it properly until this commit.

Also I can confirm that it appears to be decoding things properly, which implies the encoding is what is actually incorrect.

[awilfox]

I believe that some of these are actually the tests being wrong. For instance:

# CHECK: adda.l  #50402580, %a1
0xd3 0xfc 0x03 0x01 0x15 0x14

This test looks incorrect to me. 50402580 gives value 0x0301'1514, but the LLVM source even explicitly states:

https://github.com/llvm/llvm-project/blob/e5a41f0afc152cc24b8fef3aa177ef53b2e77c43/llvm/lib/Target/M68k/MCTargetDesc/M68kMCCodeEmitter.cpp#L103-L110

But now I am concerned: do these tests pass on little endian hosts? In that case, it's possible that swapWord isn't working correctly. I will test now on an Arm64 (Apple M1) system and check.

[awilfox]

Yes, the tests pass on Arm64. Which means either I am correct, and the values are correct on BE hosts but not being swapped properly on LE hosts, or the original report was correct, and the values are correct on LE hosts but not being swapped properly on BE hosts. I'll try and do some further analysis with GNU binutils to see what they do with these inputs.

[awilfox]

Having twiddled the bits manually through various disassemblers, yes, the tests are correct. Something is not working correctly on BE hosts. Sorry if this is a bit noisy, by the way. This is my first time dealing with M68k opcodes in raw byte format, and the descriptions are sometimes a bit unclear to me.

[awilfox]

It seems to be that the problem is that encodeInstruction is indeed unconditionally swapping 16-bit words. If we change swapWord to unconditionally swap too, i.e. change MCTargetInfo/M68kBaseInfo.h in this manner:

@@ -85,9 +85,10 @@ template <typename value_t> value_t swapWord(value_t Val) {
   Val = support::endian::byte_swap(Val, llvm::endianness::big);
   value_t NewVal = 0;
   for (unsigned i = 0U; i != NumWords; ++i) {
-    uint16_t Part = (Val >> (i * 16)) & 0xFFFF;
-    Part = support::endian::byte_swap(Part, llvm::endianness::big);
-    NewVal |= (Part << (i * 16));
+    uint16_t Lo = (Val >> (i * 16)) & 0xFFFF;
+    NewVal |= (Lo << (++i * 16));
+    uint16_t Hi = (Val >> (i * 16)) & 0xFFFF;
+    NewVal |= (Hi << ((i - 1) * 16));
   }
   return NewVal;
 }

Then the tests pass on my PPC64 (BE) host, but of course then start failing on Arm64 (LE).
