   4    These are compiled in a couple of different ways (always on a
   5    Darwin system):
   6    Basic compilation:
   7       for FILE in basic1.c basic2.c basic3.c; do
   8          clang -g -c $FILE -o ${FILE%.c}.macho.x86_64.o
   9       done
  10       clang basic1.macho.x86_64.o basic2.macho.x86_64.o basic3.macho.x86_64.o -o basic.macho.x86_64 -Wl,-dead_strip
  11
  12    LTO compilation:
  13       for FILE in basic1.c basic2.c basic3.c; do
  14          clang -g -c -flto $FILE -o ${FILE%.c}-lto.o
  15       done
  16       clang basic1-lto.o basic2-lto.o basic3-lto.o -o basic-lto.macho.x86_64 -Wl,-object_path_lto,$PWD/basic-lto.macho.x86_64.o -Wl,-dead_strip
  17       rm basic1-lto.o basic2-lto.o basic3-lto.o
  18
  19    Archive compilation (after basic compilation):
  20       ar -q libbasic.a basic2.macho.x86_64.o basic3.macho.x86_64.o
  21       clang basic1.macho.x86_64.o -lbasic -o basic-archive.macho.x86_64 -Wl,-dead_strip -L.
  22
  23    Remarks compilation:
  24       for FILE in basic1.c basic2.c basic3.c; do
  25          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
  26       done
  27       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
  28
  29     Remarks archive compilation (after remarks compilation):
  30     ar -q libbasic.a basic1.macho.x86_64.o basic2.macho.x86_64.o basic3.macho.x86_64.o
  31     clang -lbasic -L. -o basic.macho.remarks.archive.x86_64 -Wl,-dead_strip
