...alloca i33, align 8 The compilation time improve significant if running on LLVM 3.9. Unfortunately, it's not a choice for me now to upgrade it to 3.9. If anyone luckily to know what's the evolution in this area to improve the compilation time performance, pls kindly comments. thanks Xiaoyong -------------- next part -------------- An HTML attachment was scrubbed...

I'm working on the across the subprogram call optimization, and let's say the following llvm IR, @ng0 = internal global [2 x i32] [i32 2, i32 0], align 4 %t7 = alloca [16 x i8], align 16 %add.ptr = getelementptr inbounds i8* %t1, i64 40 %call = call i8* @handle_value(i8* %add.ptr, i32 3) #3 %arraydecay = getelementptr inbounds [8 x i8]* %t3, i64 0, i64 0 %arraydecay1 =
