Module and link things into that.

Also, fix a typo in an error message.

Make "verbose" output MUCH nicer. Now it tells you when you are linking a
bytecode file, or an archive, and whether it's because you called it by name,
or because you gave it a -l option, and it says "Trying" before it takes
action and prints a message in the past tense afterwards.

Make LinkFiles not skip the first file in Files.

Make LinkFiles warn you if it can't find a file and LLVM_LIB_SEARCH_PATH is
unset.

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.)

* Removed space between function name and its argument list

* Made code layout more verbose: no more '{' on a line by itself
* Pruned extra whitespace

 * Local header file goes at top
 * Remove unneeded #includes
 * Wrap code at 80 columns
 * Declare variables where they are used
 * '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.

llvm-svn: 8595

This should prevent calls to the new oerator and malloc.

Have gccld find the path to llc and gcc instead of having the library do it.

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.

llvm-svn: 8579

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.

llvm-svn: 8328

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.
