Track the debug locations of the incoming values to newly-created phis, and apply merged debug locations to the phis. A merged location will be on line 0, but will have the correct scope set. This improves crash reporting when an inlined instruction with a merged location triggers a machine exception. A debugger will be able to narrow down the crash to the correct inlined scope, instead of simply pointing to the outer scope of the caller. Taken together with a change allows generating merged line-0 locations for instructions which aren't calls, this results in a 0.5% increase in the uncompressed size of the .debug_line section of a stage2+Release build of clang (-O3 -g). rdar://33858697 Differential Revision: https://reviews.llvm.org/D45397 llvm-svn: 330227 |
