This is the first patch I've sent to this project. Please be gentle :) LLVM fails to remove the dead load in the following code when running $./llvm-as -o - test.ll | ./opt -O3 -o - | ./llvm-dis -o - %t = type { i32 } declare void @foo(i8*) define void @f(%t* noalias nocapture %stuff ) { %p = getelementptr inbounds %t* %stuff, i32 0, i32 0 %before = load i32* %p call void

Here is another change I'd like to suggest to the BasicAliasAnalysis. LLVM fails to remove the dead store in the following code: %t = type { i32 } define void @f(%t* noalias nocapture %stuff ) { %p = getelementptr inbounds %t* %stuff, i32 0, i32 0 store i32 1, i32* %p; <-- This store is dead %x = load i32* inttoptr (i32 12345 to i32*) store i32 %x, i32* %p ret
