Misha Brukman c10bf39a7d I'm gonna be picky and say we don't really need that trailing slash "lib/"

Misha Brukman 44a562bba6 Make sure we ONLY add a `-load' switch to the JIT command line if the file is
verified as having an ELF header. This fixes PR151.

Misha Brukman 1df12628a0 When writing out the runner script, add -load=<lib> lines to pull in all the
shared objects automagically, so it doesn't have to be done by hand.

Brian Gaeke 1d9515b0a1 Do not assume the first file is a bytecode file. Instead, construct a dummy
Module and link things into that.

Also, fix a typo in an error message.

Brian Gaeke 484f2c7442 1. Use better error messages in LinkFiles().
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.)

Chris Lattner 65d93e208b Minor cleanups:
* 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

John Criswell b533bde540 Removed linking functionality from gccld.cpp and moved it to linker.cpp.
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
2003-09-19 20:24:23 +00:00
John Criswell 8ecc30249f Refactored gccld into three C++ source files.
Added code ignore bytecode link failures when generating native code.
Moved native code and bytecode generation out of the main() function.

John Criswell a2748c267b Replaced the call to strdup() with a new operator followed by a strcpy().
This should prevent calls to the new oerator and malloc.

llvm-svn: 8587
2003-09-17 19:14:41 +00:00
John Criswell 0217b1beb3 Added the use of the const keyword.
Have gccld find the path to llc and gcc instead of having the library do it.

2003-09-17 19:04:22 +00:00
John Criswell f22d845bd7 Removed the use of the environ variable and instead use the environment array
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
2003-09-17 15:20:51 +00:00
John Criswell 1997a34e26 Added the -native option.
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).

John Criswell a3ce8b48b0 Added code that makes the bytecode file readable (needed by the generated shell
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
2003-09-02 21:11:22 +00:00
John Criswell 06327da723 Modified the code so that it uses the MakeFileExecutable() method. The new
library code now adds all execute bits that are allowed by the umask value to
the file's current permission bits.

llvm-svn: 8325
2003-09-02 20:17:20 +00:00
John Criswell c907487c22 "Help keep our secrets secret."
Added code to respect the umask value.  Before, files were generated world
readable, which may not be desirable for all installations.

Brian Gaeke 5bfa37f4df gccld.cpp:
Fix typo in header.
 Add IsArchive static method.
 Roll LoadLibraryFromDirectory() into LoadLibrary(), and factor
  LoadLibraryExactName() out of the result. Instead of treating the current
  directory specially, just insert it into LibPaths in the beginning of
  main().
 Make LoadLibrary() take a "search" flag that says whether to search for the
  correct library, or just trust that LibName is right.
 Make LinkLibrary() take a "search" flag, and pass it to LoadLibrary().
 Change the for-loop over InputFilenames to detect ar archives and link them
  in as libraries without searching.
 Change the for-loop over Libraries to explicitly turn on the "search" flag
  to LinkLibrary() that makes LoadLibrary() search for the correct library
  (i.e., when processing -lNAME options.)
