Subject: [mlir:LLVM] Fix translation of DISubRangeAttr to LLVM
X-Git-Tag: upstream/17.0.6~28454
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e83446f43b23cf4a4274cb3bde09883dcd9f7b4d;p=platform%2Fupstream%2Fllvm.git

[mlir:LLVM] Fix translation of DISubRangeAttr to LLVM

We were missing DISubRangeAttr in the type switch. This
also updates a few of the range parameters to be optional.
