Rafael Espindola 26b57ffa27 Add a lto_codegen_compile_to_file to avoid producing a file, reading it to 
memory and writing it back to disk.

Rafael Espindola 5b778b2e60 Use lazy parsing in LTO. Unfortunately this is only a 3% time saving for 
'ar'. Have to figure out how to make libLTO even lazier.

Rafael Espindola c78f65775a Simplify the computation of undefined symbols. Instead of walking 
functions and initializers, just report the declarations present in
the module.

The motivation is to open the way for using the lazy module parsing,
which should speed up clients that just want a symbol list (nm, ar).

This is slightly less precise, but since both -strip-dead-prototypes
and -globaldce are part of the standard pipeline, this shouldn't
change the result for clang/dragonegg produced binaries.

Any decl in an IL file was also put there because a FE expected it
to be necessary, so this should not be a problem for "-O0 -emit-llvm".

As a sanity check, I have bootstrapped clang on linux and built
firefox on both linux and darwin. A clang bootstrap on darwin
with LTO fails with or without this patch because, ironically,
the linker doesn't like the combination of dead_strip and LTO
when building libLTO.so :-)

Rafael Espindola ab959a2e68 Use RequiresNullTerminator to create buffers without a null terminator 
instead of copying.

Oscar Fuentes 64d05bc281 Add LTO and gold plugin to the CMake build. Linux-only, support for 
other systems pending.

PR9456.

llvm-svn: 127466
 2011-03-11 15:44:24 +00:00
Rafael Espindola 1e49a6d9bc Add a special streamer to libLTO that just records symbols definitions and 
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)

Rafael Espindola fac373cacb Switch LTO to use MC. This takes the linking of libxul.so from about 7m to 
6m30.

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.

 2011-02-08 22:40:47 +00:00
Rafael Espindola 08bccdad19 Don't tell the linker about available_externally definitions. If we do, it will 
complain about duplicated definitions.

Devang Patel 39bd6cebcd Do not include DataTypes.h in llvm-c/lto.h. 
This means avoid using uint32_t. This patch reverts r112200 and fixes original  problem by fixing argument type in lto.cpp.

Rafael Espindola 56eb741237 Initial support for the cfi directives. This is just enough to get

Daniel Dunbar ef47b66d52 lto: Respect LLVM_VERSION_INFO make variable, since setting CC arguments with 
spaces gives tests fits and shell escaping is an art best left to jabberwockies.

Dan Gohman a2233f2801 Make tool_output_file's raw_ostream instance a member variable instead 
of a base class.

This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.

Daniel Dunbar a8272596bc lto: Fix an inverted conditional which prevented the addition of symbols scraped 
from inline assembly, except in cases where they had already been seen (in which
case they would get added twice).
