Remove 'inlinedAt:' from MDLocalVariable. Besides saving some memory (variables with it seem to be single largest `Metadata` contributer to memory usage right now in -g -flto builds), this stops optimization and backend passes from having to change local variables. The 'inlinedAt:' field was used by the backend in two ways: 1. To tell the backend whether and into what a variable was inlined. 2. To create a unique id for each inlined variable. Instead, rely on the 'inlinedAt:' field of the intrinsic's `!dbg` attachment, and change the DWARF backend to use a typedef called `InlinedVariable` which is `std::pair<MDLocalVariable*, MDLocation*>`. This `DebugLoc` is already passed reliably through the backend (as verified by r234021). This commit removes the check from r234021, but I added a new check (that will survive) in r235048, and changed the `DIBuilder` API in r235041 to require a `!dbg` attachment whose 'scope:` is in the same `MDSubprogram` as the variable's. If this breaks your out-of-tree testcases, perhaps the script I used (mdlocalvariable-drop-inlinedat.sh) will help; I'll attach it to PR22778 in a moment. llvm-svn: 235050 |
