It actually fails with an llvm assertion error, we just have assertions disabled.

DilumAluthge · 2022-02-27T05:08:16Z

@vchuravy and I recently enabled assertions for the llvmpasses CI job.

Should we also enable assertions for the asan CI job?

timholy · 2022-02-28T10:46:06Z

I'd like to have this working too, for debugging #44338. I'm marking this for 1.8.

timholy · 2022-03-01T15:44:23Z

Here's some diagnosis (I don't yet know how to fix it): while compiling

julia/base/float.jl

Lines 211 to 225 in 3a5dc09

    
           function Float32(x::Int128) 
        
               x == 0 && return 0f0 
        
               s = ((x >>> 96) % UInt32) & 0x8000_0000 # sign bit 
        
               x = abs(x) % UInt128 
        
               n = 128-leading_zeros(x) # ndigits0z(x,2) 
        
               if n <= 24 
        
                   y = ((x % UInt32) << (24-n)) & 0x007f_ffff 
        
               else 
        
                   y = ((x >> (n-25)) % UInt32) & 0x00ff_ffff # keep 1 extra bit 
        
                   y = (y+one(UInt32))>>1 # round, ties up (extra leading bit in case of next exponent) 
        
                   y &= ~UInt32(trailing_zeros(x) == (n-25)) # fix last bit to round to even 
        
               end 
        
               d = ((n+126) % UInt32) << 23 
        
               reinterpret(Float32, s | d + y) 
        
           end

in codegen we have to convert the constant 0f0 to an LLVM constant. In

julia/src/intrinsics.cpp

Lines 165 to 166 in 3a5dc09

    
           return ConstantFP::get(ctx.builder.getContext(), 
        
                   APFloat(lt->getFltSemantics(), APInt(32, data32)));

, data32 is correctly 0. However, for reasons mysterious to me, that call ends up borking at https://elixir.bootlin.com/llvm/llvmorg-13-init/source/llvm/include/llvm/IR/Type.h#L450. In other words, I think we're expecting that APFloat(lt->getFltSemantics(), APInt(32, data32)) return type IEEESingle and it's not.

Is it relevant that APInt apparently takes a uint64_t? https://llvm.org/doxygen/classllvm_1_1APInt.html#a6286f2ba84c5ad11f4a90d57cb1dd293 (not sure if that's the right LLVM version, though). Making it so doesn't fix the build error.

Oh, and here's the relevant portion of the stacktrace:
