* Remove linkonce_odr_auto_hide.Rafael Espindola2013-11-011-3/+0
| | | | | | | | | | | | | | | linkonce_odr_auto_hide was in incomplete attempt to implement a way for the linker to hide symbols that are known to be available in every TU and whose addresses are not relevant for a particular DSO. It was redundant in that it all its uses are equivalent to linkonce_odr+unnamed_addr. Unlike those, it has never been connected to clang or llvm's optimizers, so it was effectively dead. Given that nothing produces it, this patch just nukes it (other than the llvm-c enum value). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193865 91177308-0d34-0410-b5e6-96231b3b80d8
* Use LTO_SYMBOL_SCOPE_DEFAULT_CAN_BE_HIDDEN instead of the "dso list".Rafael Espindola2013-10-311-2/+24
| | | | | | | | | | | | | | | | | | | | | | 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
* Move getSymbol to TargetLoweringObjectFile.Rafael Espindola2013-10-291-1/+1
| | | | | | This allows constructing a Mangler with just a TargetMachine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193630 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a MCTargetStreamer interface.Rafael Espindola2013-10-081-1/+1
| | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192181 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove some really nasty uses of hasRawTextSupport.Rafael Espindola2013-10-051-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192035 91177308-0d34-0410-b5e6-96231b3b80d8
