[PATCH] D126546: [InstCombine] decomposeSimpleLinearExpr should bail out on negative operands.

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/test/Transforms/InstCombine/neg-alloca.ll:1
+; RUN: opt -S -passes=instcombine < %s | FileCheck %s
+ at test = external global [1 x i32], align 16
----------------
Please use the llvm/utils/update_test_checks.py script to generate CHECK lines.

Also, I think that this test case may be reduced, I don't think you really need much more than then mul+add+alloca+bitcast sequence?
