Fix inserting new elements in a specified location. We were only handling the 'a' and 'b' options during moves before. llvm-svn: 186721

Test adding a member to a particular position
RUN: touch %t.foo
RUN: touch %t.bar
RUN: rm -f %t.a
RUN: llvm-ar rc %t.a %t.foo %t.bar
RUN: touch %t.zed
RUN: llvm-ar rca %t.foo %t.a %t.zed
RUN: llvm-ar t %t.a | FileCheck %s
CHECK: .foo
CHECK-NEXT: .zed
CHECK-NEXT: .bar
Handle replacement into a position past the original member. We were incorrectly computing where to insert a member if it was replacing a previous member that was before the insert point. llvm-svn: 186792

Don't depend on a llvm-ar specific behavior. GNU ar when not given the a or b modifiers replaces archive members in the same location of the old ones. I am about to implement that in llvm-ar. For now, just don't depend on the current llvm-ar behavior on this test. llvm-svn: 186823

Replace archive members in the old position. This matches gnu archive behavior and since archive member order can change which member is used, not changing the order on replacement looks like the right thing to do. This patch also refactors the logic for which archive member to keep and whether to move it to a helper function (computeInsertAction). The nesting in computeNewArchiveMembers was getting a bit confusing. llvm-svn: 186829
