/* This is the main file used to produce the basic* objects that are
   used for the dsymutil tests.

   These are compiled in a couple of different ways (always on a
   Darwin system):
   Basic compilation:
      for FILE in basic1.c basic2.c basic3.c; do
         clang -g -c $FILE -o ${FILE%.c}.macho.x86_64.o
      done
      clang basic1.macho.x86_64.o basic2.macho.x86_64.o basic3.macho.x86_64.o -o basic.macho.x86_64 -Wl,-dead_strip

   LTO compilation:
      for FILE in basic1.c basic2.c basic3.c; do
         clang -g -c -flto $FILE -o ${FILE%.c}-lto.o
      done
      clang basic1-lto.o basic2-lto.o basic3-lto.o -o basic-lto.macho.x86_64 -Wl,-object_path_lto,$PWD/basic-lto.macho.x86_64.o -Wl,-dead_strip
      rm basic1-lto.o basic2-lto.o basic3-lto.o

   Archive compilation (after basic compilation):
      ar -q libbasic.a basic2.macho.x86_64.o basic3.macho.x86_64.o
      clang basic1.macho.x86_64.o -lbasic -o basic-archive.macho.x86_64 -Wl,-dead_strip -L.

   Remarks compilation:
      for FILE in basic1.c basic2.c basic3.c; do
         clang -gline-tables-only -c $FILE -fsave-optimization-record=bitstream -foptimization-record-file=/remarks/${FILE%.c}.macho.remarks.x86_64.opt.bitstream -o ${FILE%.c}.macho.remarks.x86_64.o
      done
      clang basic1.macho.remarks.x86_64.o basic2.macho.remarks.x86_64.o basic3.macho.remarks.x86_64.o -o basic.macho.remarks.x86_64 -Wl,-dead_strip

    Remarks archive compilation (after remarks compilation):
    ar -q libbasic.a basic1.macho.x86_64.o basic2.macho.x86_64.o basic3.macho.x86_64.o
    clang -lbasic -L. -o basic.macho.remarks.archive.x86_64 -Wl,-dead_strip
