when they have to run a gccld shell script without having lli in their path.
This is intended to address Bug 289.

Also, emit the traditional syntax ${1+"$@"} for passing all of a shell script's
args to a subprocess. If you have arguments that have spaces in them, $* will
not preserve the quoting (i.e., the quoted string "foo bar" as an argument will
end up as two arguments "foo" "bar" to lli.)

2. I think the caller of LinkFiles() should not ignore a true return value.
   (If you have a good reason why it ought to, feel free to revert
   this. It's just something that's been bugging me for a while.)

 * Remove unneeded #includes
 * Wrap code at 80 columns

 * 'register' is not needed
 * Use 'unsigned' instead of 'int' variables where possible

Renamed functions that were all lower-case.
Moved functions from util.cpp into linker.cpp or gccld.cpp.
Removed util.h and created gccld.h.
Refactored the linker functionality in linker.cpp so that it is easier to
follow, easier to modify, and it's library/object file search behavior is
easier to understand and document.
Added code to include library paths when doing native linking, but this
causes problems and is currently #ifdef'd out.

llvm-svn: 8609

Added code ignore bytecode link failures when generating native code.
Moved native code and bytecode generation out of the main() function.

This should prevent calls to the new oerator and malloc.

passed into main().  This may (or may not) be more portable, but it looks
nicer.
Added functions to copy the environment array and modify the copy, thus
preserving the environment.
Switched from using system() to using ExecWait().
The code now removes the assembly file generated when using the -native option.
Fixed the remove_env() function: The previous revision truncated the
environment variable list.  This version just zaps the variable as intended.

With this option, gccld links the program into LLVM bytecode and a native code
binary.  This allows llvmgcc to correctly tell GNU configure scripts when
things aren't defined properly (because the native link will fail).

script).
Removed the use of sys/types.h and sys/stat.h.
Modified FileExists() so that it uses the access() system call to check for
file existance.  This requires less header files and might even be a tad bit
faster.

library code now adds all execute bits that are allowed by the umask value to
the file's current permission bits.

llvm-svn: 8325

Added code to respect the umask value.  Before, files were generated world
readable, which may not be desirable for all installations.
