      Have asm printers use formatted_raw_ostream directly to avoid a

      Reapply my previous asmprinter changes now with more testing and two · 8c9a96b9
      Chris Lattner authored
      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.

      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").

      assert(0) -> LLVM_UNREACHABLE. · 56d06597
      Torok Edwin authored
      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.

      Change MachineInstrBuilder::addReg() to take a flag instead of a list of · f7b83c7a

      booleans. This gives a better indication of what the "addReg()" is
      doing. Remembering what all of those booleans mean isn't easy, especially if you
      aren't spending all of your time in that code.
      
      I took Jakob's suggestion and made it illegal to pass in "true" for the
      flag. This should hopefully prevent any unintended misuse of this (by reverting
      to the old way of using addReg()).

      Second attempt: · 084669a1
      Bill Wendling authored
      Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
      use the old behavior, the flag is -O0. This change allows for finer-grained
      control over which optimizations are run at different -O levels.
      
      Most of this work was pretty mechanical. The majority of the fixes came from
      verifying that a "fast" variable wasn't used anymore. The JIT still uses a
      "Fast" flag. I'll change the JIT with a follow-up patch.

      Introduce new linkage types linkonce_odr, weak_odr, common_odr · 12da8ce3

      and extern_weak_odr.  These are the same as the non-odr versions,
      except that they indicate that the global will only be overridden
      by an *equivalent* global.  In C, a function with weak linkage can
      be overridden by a function which behaves completely differently.
      This means that IP passes have to skip weak functions, since any
      deductions made from the function definition might be wrong, since
      the definition could be replaced by something completely different
      at link time.   This is not allowed in C++, thanks to the ODR
      (One-Definition-Rule): if a function is replaced by another at
      link-time, then the new function must be the same as the original
      function.  If a language knows that a function or other global can
      only be overridden by an equivalent global, it can give it the
      weak_odr linkage type, and the optimizers will understand that it
      is alright to make deductions based on the function body.  The
      code generators on the other hand map weak and weak_odr linkage
      to the same thing.
