[LLVMdev] opt -globaldce -deadargelim yields different result then when run separately

[Torvald Riegel]

Hi,

when I run opt -globaldce -deadargelim on a module, deadargelim removes less 
arguments than when I run opt separately for the two passes. The module has 
dead functions that hold references to other functions, which makes the 
latter intrinsically live for deadargelim. -debug-pass=Executions shows no 
other passes being run before deadargelim.
Why is that so?

Thanks,
Torvald
