Duncan P. N. Exon Smith 0c1aee0b16 DI: Require subprogram definitions to be distinct ... As a follow-up to r246098, require `DISubprogram` definitions (`isDefinition: true`) to be 'distinct'. Specifically, add an assembler check, a verifier check, and bitcode upgrading logic to combat testcase bitrot after the `DIBuilder` change. While working on the testcases, I realized that test/Linker/subprogram-linkonce-weak-odr.ll isn't relevant anymore. Its purpose was to check for a corner case in PR22792 where two subprogram definitions match exactly and share the same metadata node. The new verifier check, requiring that subprogram definitions are 'distinct', precludes that possibility. I updated almost all the IR with the following script: git grep -l -E -e '= !DISubprogram\(.* isDefinition: true' | grep -v test/Bitcode | xargs sed -i '' -e 's/= \(!DISubprogram(.*, isDefinition: true\)/= distinct \1/' Likely some variant of would work for out-of-tree testcases. llvm-svn: 246327		2015-08-28 20:26:49 +00:00
