* [llvm-readobj] Change -t to --symbols in tests. NFCFangrui Song2019-05-011-1/+1
| | | | | | | | | | -t is --symbols in llvm-readobj but --section-details (unimplemented) in readelf. The confusing option should not be used since we aim for improving compatibility. Keep just one llvm-readobj -t use case in test/tools/llvm-readobj/symbols.test llvm-svn: 359661
* [LTO] Make processing of combined module more consistentVitaly Buka2017-12-161-1/+1
| | | | | | | | | | | | | | | | | Summary: 1. Use stream 0 only for combined module. Previously if combined module was not processes ThinLTO used the stream for own output. However small changes in input, could trigger combined module and shuffle outputs making life of llvm::LTO harder. 2. Always process combined module and write output to stream 0. Processing empty combined module is cheap and allows llvm::LTO users to avoid implementing processing which is already done in llvm::LTO.

* [LTO] Fix the interaction between linker redefined symbols and ThinLTODavide Italiano2017-07-061-0/+16
This is the same as r304719 but for ThinLTO. The substantial difference is that in this case we don't have whole visibility, just the summary. In the LTO case, when we got the resolution for the input file we could just see if the linker told us whether a symbol was linker redefined (using --wrap or --defsym) and switch the linkage directly for the GV. Here, we have the summary. So, we record that the linkage changed from <whatever it was> to $weakany to prevent IPOs across this symbol boundaries and actually just switch the linkage at FunctionImport time. This patch should also fixes the lld bits (as all the scaffolding for communicating if a symbol is linker redefined should be there & should be the same), but I'll make sure to add some tests there as well. Fixes PR33192. Differential Revision: https://reviews.llvm.org/D35064 llvm-svn: 307303
