[PATCH] D20147: [WIP] DebugInfo: New metadata representation for global variables.

[Peter Collingbourne via llvm-commits]

pcc added a comment.

While it's possible that that would result in a performance improvement, it's unclear that that would be the case, and I don't think we should make such a change without evidence. For ThinLTO and llvm-ar a more effective performance improvement would be to pre-compute the symbol table (see pr27551), which would avoid the need to read most of the bitcode file. There's also the possibility that lazy loading GlobalVariables would slow things down, as the benefit of lazy loading globals would generally be less than for functions.
