* Protect user-supplied runtime library functions in LTOJustin Bogner2013-11-121-0/+27
| | | | | | | | | | | | | | Add user-supplied C runtime and compiler-rt library functions to llvm.compiler.used to protect them from premature optimization by passes like -globalopt and -ipsccp. Calls to (seemingly unused) runtime library functions can be added by -instcombine and instruction lowering. Patch by Duncan Exon Smith, thanks!

* Use LTO_SYMBOL_SCOPE_DEFAULT_CAN_BE_HIDDEN instead of the "dso list".Rafael Espindola2013-10-311-0/+42
| | | | | | | | | | | | | | | | | | | | | | There are two ways one could implement hiding of linkonce_odr symbols in LTO: * LLVM tells the linker which symbols can be hidden if not used from native files. * The linker tells LLVM which symbols are not used from other object files, but will be put in the dso symbol table if present. GOLD's API is the second option. It was implemented almost 1:1 in llvm by passing the list down to internalize. LLVM already had partial support for the first option. It is also very similar to how ld64 handles hiding these symbols when *not* doing LTO. This patch then * removes the APIs for the DSO list. * marks LTO_SYMBOL_SCOPE_DEFAULT_CAN_BE_HIDDEN all linkonce_odr unnamed_addr global values and other linkonce_odr whose address is not used. * makes the gold plugin responsible for handling the API mismatch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193800 91177308-0d34-0410-b5e6-96231b3b80d8
* Optimize more linkonce_odr values during LTO.Rafael Espindola2013-10-211-0/+3
| | | | | | | | | | | When a linkonce_odr value that is on the dso list is not unnamed_addr we can still look to see if anything is actually using its address. If not, it is safe to hide it. This patch implements that by moving GlobalStatus to Transforms/Utils and using it in Internalize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193090 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix object file writing in llvm-lto on Windows.Rafael Espindola2013-10-042-4/+1
| | | | | | | | We were writing in text mode. Patch by Greg Bedwell. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191985 91177308-0d34-0410-b5e6-96231b3b80d8
* Optimize linkonce_odr unnamed_addr functions during LTO.Rafael Espindola2013-10-031-0/+8
| | | | | | | | | | | Generalize the API so we can distinguish symbols that are needed just for a DSO symbol table from those that are used from some native .o. The symbols that are only wanted for the dso symbol table can be dropped if llvm can prove every other dso has a copy (linkonce_odr) and the address is not important (unnamed_addr). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191922 91177308-0d34-0410-b5e6-96231b3b80d8
