The failure mode looks similar to crbug.com/629141

Comment 2 Hans Wennborg 2016-07-20 16:00:16 PDT

Bisection points to r275561 - code hoisting pass based on GVN


To reproduce:

Build Release+Asserts Clang at this revision for 32-bit windows

Use that to configure a Release+Asserts 32-bit Windows build, and build llvm-mc, then run it like:

D:/src/llvm/build.bootstrap/./bin\llvm-mc.EXE D:\src\llvm\test\MC\Sparc\sparc64-ctrl-instructions.s -triple=sparc64-unknown-linux-gnu -show-encoding

I do not have access to a windows 32-bit machine.
From this description it sounds like llvm-mc is miscompiled.
Would you be able to bisect the problem and report a reduced testcase?

Here is how I would do that:

Build a good llvm-mc with a good compiler and keep around all the .o files.
Build a bad llvm-mc with the faulty compiler.
Link together half of good and half of bad .o files and check whether it fails.
Iterate this step halving at each iteration the number of .o files that may contain the miscompilation.

Once you have a .o file that is miscompiled, bisect on the number of GVN expressions hoisted: compile that .cpp file with the same options and adding "-mllvm -gvn-max-hoisted=10000 and then bisect again that number until finding N for which llvm-mc passes and N+1 fails.

Finally get the output of "-mllvm -print-after-all -mllvm -print-before-all" for both N and N+1.

Comment 4 Hans Wennborg 2016-07-21 13:29:22 PDT

Thanks! I've bisected with -gvn-max-hoisted and found that the function that seems to be breaking is SparcAsmParser::parseMEMOperand

I'll attach the IR before and after hoisting of that function.

parseMEMOperand before hoisting

Comment 6 Hans Wennborg 2016-07-21 13:30:14 PDT

Created attachment 16781 [details]
parseMEMOperand after hoisting

Comment 7 Hans Wennborg 2016-07-21 13:36:59 PDT

diffing before and after shows that it seems we're introducing a new alloca (%21)  in the if.end18 block. This is problematic, because it gets inserted after an inalloca (%argmem) which is live there. I think that's the source of our bug, and it also explains why this only happens on 32-bit Windows.

Comment 8 Hans Wennborg 2016-07-21 13:59:50 PDT

I'm not exactly sure what's going on, but looking at the diff again, maybe it's something like this:

in cond.true there is:

  %20 = getelementptr inbounds <{ %"class.std::unique_ptr.203"*, i32, %"class.std::unique_ptr.203" }>, <{ %"class.std::unique_ptr.203"*, i32, %"class.std::unique_ptr.203" }>* %argmem, i32 0, i32 0, !dbg !27007^M
  store %"class.std::unique_ptr.203"* %ref.tmp20, %"class.std::unique_ptr.203"** %20, align 4, !dbg !27007

%ref.tmp20 is an alloca in the entry block

When hoisting, the pass hoists both the gep and the store, cloning the value (the alloca) and putting that at the hoist point. (GVNHoist.cpp's makeOperandsAvailable)

Since that means inserting an alloca after a live inalloca, it breaks the program, but it also seems bad in general to insert an alloca into the non-entry block.

Maybe the pass should bail out when Val is an AllocInst? Or maybe it should check if it's from the entry block and if so insert the clone there as well?

Thanks Hans!
It is very helpful to see the diff.
I will have a closer look and I will submit a patch to fix the problem.
