similar to: [LLVMdev] "distinct" metadata nodes are ...?

Aha, okay. I had noticed that the column-info hack went away. So the distinct-ness implies the scope implicit in the inlined call, which later on will be turned into the explicit inlined_subroutine entry. That seems… indirect. I have to say, the LangRef page's words about "merge based on content" is not really to the point. It's like saying the purpose of a street-corner

Branching off from a discussion of improvements to DIGlobalVariable representations that Adrian's working on - got me thinking about related changes that have already been made to DISubprogram. To reduce duplicate debug info when things like linkonce_odr functions were deduplicated in LTO linking, the relationship between a CU and DISubprogram was inverted (instead of a CU maintaining a list

Trying to wrap my brain around this, so a few questions below. =) On Thu, Dec 15, 2016 at 10:54 AM, David Blaikie <dblaikie at gmail.com> wrote: > Branching off from a discussion of improvements to DIGlobalVariable > representations that Adrian's working on - got me thinking about related > changes that have already been made to DISubprogram. > > To reduce duplicate

A few disjoint thoughts; sorry they're so delayed (I skimmed the responses below, and I think these are still relevant/not covered elsewhere). Firstly, why *should* DISubprogram definitions be distinct? There were two reasons this was valuable (this was from before there was a cu: link). - It helped to fix long-standing bugs in the IRLinker, where uniqued-DISubprograms in different compile

Hi, I would like to implement a fix to how LLVM handles/creates debug info for entities declared inside a basic block. Below you will find 5 parts: 1. Motivation for this fix. 2. Background explaining the cases that need to be fixed. 3. An example for each case. 4. Proposal on how to represent each case in dwarf. 5. Secondary (workaround) proposal which might be
