Rafael Espindola 5d03d46127 Point to libLTO with -L/PATH/ -lLTO so that it is found in the install 
directory.
Patch by Markus Trippelsdorf.

Daniel Dunbar 96d812a68d build: Tidy up a bunch of tool Makefiles, and simplify where possible using the

Ivan Krasin 639222d090 use 64-bit types instead of off_t/size_t to avoid the issue when 
gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686)
and the rest of LLVM is built w/o Large File Support
(sizeof(off_t) == 32 on i686) which corrupts the stack.

Oscar Fuentes a4445d6a51 CMake builds gold by default since revision 127466. This is 
inconsistent with autoconf, which by default set BINUTILS_INCDIR to
empty and exclude gold from target list.

Based on a patch by Haitao Li!

Rafael Espindola ece7c9c282 If present, use gold's support for getting a file view. This prevents having 
to map the file both in the linker and in the plugin.

llvm-svn: 129109
 2011-04-07 21:11:00 +00:00
Rafael Espindola 26b57ffa27 Add a lto_codegen_compile_to_file to avoid producing a file, reading it to

Rafael Espindola 7e5fe6ce1c Gold now rescans archives as needed, so the pass-through options are not 
necessary anymore.

llvm-svn: 126580
 2011-02-27 20:30:22 +00:00
Rafael Espindola 92c06ba158 bfd was fixed, remove the work around.

Rafael Espindola 9ef90d5b35 Dispose modules early and only create codegen when the plugin is being 
used by the linker and not by nm or ar.

llvm-svn: 126089
 2011-02-20 18:28:29 +00:00
Rafael Espindola d4f34d840e Add modules to codegen as soon as possible. This reduces the link time 
of libxul from 12m31.084s to 7m1.359s.

llvm-svn: 126052
 2011-02-19 21:49:57 +00:00

llvm-svn: 125663
 2011-02-16 11:19:44 +00:00
Rafael Espindola 70d8015063 Switch llvm to using comdats. For now always use groups with a single 
section.

llvm-svn: 125526
 2011-02-14 22:23:49 +00:00
Rafael Espindola 56e41f7f0b Don't open the file again in the gold plugin. To be able to do this, update 
MemoryBuffer::getOpenFile to not close the file descriptor.

Charles Davis 54c9eb6fff Now to chant the magical incantation that will exorcise the System library 
from LLVM forever:

grep -lR "llvm/System" * | grep -v .svn | xargs sed -ie 's#llvm/System#llvm/Support#g'

NAKAMURA Takumi 217cadd434 Don't build redundant libLLVMgold.a. 
Building archive would be executed due to definition of BUILD_ARCHIVE,
even if BUILD_ARCHIVE = "0".

Nick, please review.

gold plugin.

llvm-svn: 107126
 2010-06-29 11:07:47 +00:00
Rafael Espindola ef49815638 Add an extra-library-path option to the plugin. This is used to support 
having a library both as bitcode and native code. We want to use the
bitcode first, but if codegen produces new undefined references we have to use
the native code to satisfy those references.

Gold has no notion of bitcode and native search directories, so instead it has
an API where the plugin can instruct it to look for the libraries it is passing
to it. This patch uses that API.

llvm-svn: 106674
 2010-06-23 20:20:59 +00:00
Rafael Espindola 9d94ebf1b6 add_input_file and add_input_library now take const arguments, remove the 
const_cast.

llvm-svn: 106410
 2010-06-21 02:23:12 +00:00
Rafael Espindola 8297640062 Add a pass-through option to the plugin. The use case for this option is to 
ask the linker to take another look into some library or object. The case when
one might want to do this is when codegen introduces a new undefined reference.
The canonical example is libgcc.

llvm-svn: 106303

Rafael Espindola 77b6d01906 Don't produce output only if *all* files are unused.

Rafael Espindola 00121827b2 Don't preserve all symbols in a .so and instead trust gold to know what is 
needed. The result is that now we are able to drop unnecessary symbol from
shared libraries.

llvm-svn: 105389
 2010-06-03 14:45:44 +00:00
Rafael Espindola 0af6889b89 Avoid renaming loadable modules at install time. Now the gold plugin is named 
LLVMgold.so both in both the build and install directories.

llvm-svn: 103897
