2009-07-22remove the SelectSectionForMachineConst hook, replacing it withChris Lattner
a new getSectionForMergableConstant hook. This removes one dependence of TAI on Type, and provides the hook with enough info to make the right decision based on whether the global has relocations etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76705 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Pass in the unfortunately named "LessPrivatePrefix" for theBill Wendling
"LinkerPrivatePrefix". It seems to have been used in only one place before I started this "linker_private" business. I'm thinking that a rename is in order... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76479 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-20implement a new magic global "llvm.compiler.used" which is like llvm.used, butChris Lattner
doesn't cause ".no_dead_strip" to be emitted on darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76399 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-17remove AsmPrinter::findGlobalValue, just use Value::stripPointerCasts instead.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76246 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17these two pieces of code are the same because we alwaysChris Lattner
emit the EHFrame label next to the section_eh_frame and eh_frame_common labels. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76234 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-17Untangle a snarl that I discovered when updating the mangler,Chris Lattner
starting in getCurrentFunctionEHName. Among other problems, we would try to privative a "foo.eh" label, but end up emitting the label as _Lfoo.eh instead of L_foo.eh on darwin. This is really bad, and the linker has always tolerated these labels existing. For now, just emit them as _foo.eh. This patch also fixes problems with ".eh" labels on unnamed functions and eliminates two strangely defined TargetAsmInfo hooks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76231 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-16Skip special LLVM prefix '1' while emitting linknage name.Devang Patel
This prefix is used by LLVM to inform the asm printer to not emit usual global symbol prefix before the symbol name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75875 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14Have asm printers use formatted_raw_ostream directly to avoid aDavid Greene
dynamic_cast<>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75670 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Reapply my previous asmprinter changes now with more testing and two Chris Lattner
additional bug fixes: 1. The bug that everyone hit was a problem in the asmprinter where it would remove $stub but keep the L prefix on a name when emitting the indirect symbol. This is easy to fix by keeping the name of the stub and the name of the symbol in a StringMap instead of just keeping a StringSet and trying to reconstruct it late. 2. There was a problem printing the personality function. The current logic to print out the personality function from the DWARF information is a bit of a cesspool right now that duplicates a bunch of other logic in the asm printer. The short version of it is that it depends on emitting both the L and _ prefix for symbols (at least on darwin) and until I can untangle it, it is best to switch the mangler back to emitting both prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75646 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin
This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14rename getValueName -> getMangledName. These two files have veryChris Lattner
dubious looking things that I need to investigate in more detail. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75619 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Change the internal interface to makeNameProper to take a bool thatChris Lattner
indicates whether the label is private or not, instead of taking prefix stuff. One effect of this is that symbols will be generated with *just* the private prefix, instead of both the private prefix *and* the user-label-prefix, but this doesn't matter as long as it is consistent. For example we'll now get "Lfoo" instead of "L_foo". These are just assembler temporary labels anyway, so they never even make it into the .o file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75607 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-13Add infrastructure to allow post instruction printing action triggers.David Greene
We'll eventually use this to print comments in asm files and do other fun things. This adds interfaces to the AsmPrinter and changes TableGen to invoke the postInstructionAction when appropriate. It also add parameters to TargetAsmInfo to control comment layout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8
