That's correct, half fp was added after 2.7 branched. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State

http://llvm.org/docs/LangRef.html#i_inttoptr The 'inttoptr' instruction takes an integer<http://llvm.org/docs/LangRef.html#t_integer> value to cast, and a type to cast it to, which must be a pointer<http://llvm.org/docs/LangRef.html#t_pointer> type. The final example is: %Z = inttoptr <4 x i32> %G to <4 x i8*>; yields truncation of vector G to four pointers The

'It needs work' and 'it was broken' doesn't really give me an idea of what specifically is required. Specifically, what I am interested in is using unions within packed structs to force alignment. Using unions

The langref says for the 'add' instruction: Syntax: <result> = add <ty> <op1>, <op2> ; yields {ty}:result <result> = nuw add <ty> <op1>, <op2> ; yields {ty}:result <result> = nsw add <ty> <op1>, <op2> ; yields {ty}:result <result> = nuw nsw add <ty> <op1>, <op2> ;

Hi folks, It took a while, but I finally have some bandwidth to look at this. I've been reading the two existing TableGen documents: http://llvm.org/docs/TableGenFundamentals.html http://llvm.org/docs/TableGen/LangRef.html the first is linked from the index, but LangRef is not (though it has some remains in the metadata). I'm wondering what's the relationship between them two. My

Hi LLVM-dev, when working on MLIR-to-LLVM-IR conversion, I noticed that it is possible to programmatically construct a cmpxchg instruction operating on floats (or actually any type since there is no assertion on pointer element type here https://github.com/llvm/llvm-project/blob/9c2e708f0dc547d386ea528450a33ef4bd2a750b/llvm/lib/IR/Instructions.cpp#L1501), but LangRef specifies that only integers

Hi Micah, We need to fix the documentation here. We want to be able to convert vectors of integers to vectors of pointers and back. There are a few tests such as (/InstCombine/vector_gep1.ll) that check for these conversions.

I've got comments on the code change. The test cases look ok, but I haven't fully checked the math on the half-values. I checked with reference to trunk top-of-tree at revision 156617.

We've relaxed `atomicrmw xchg` to support floating point types but not cmpxchg -- the cmpxchg comparison behavior is not a floating point comparison, so that would be potentially misleading. I'd say adding the assertion is a good idea. Cheers, Nicolai On Thu, Aug 13, 2020 at 10:59 PM Chris Lattner via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Does the code generator
