This adds an option --output-filetype that can be set to either
YAML/Native(case insensitive). The linker would create the outputs
associated with the type specified by the user.
Changes all the tests to use the new option.

GNU LD driver only understood no_such_file_or_directory error and was showing
just "Unknown Error" for any other type of error. With this patch, the driver
now prints file name and error message string by default.
llvm-svn: 191070
/incremental is an option to enable incremental linking. We will eventually
want to implement the feature for better performance, but in the meantime,
we want to just ignore the option so that the linker does not output unknown
option error when it sees /incremental option.
llvm-svn: 191063
/errorReport is a command line option to let the linker to report internal
linker error information to Microsoft. For LLD that option doesn't make any
sense, so it just ignores the option.

So that we can determine what the target architecture is. Adding this
field does not mean that we are going to support non-i386 architectures
soon; there are many things to do to support them, and I'm focusing on
i386 now. But this is the first step toward multi architecture support.

Process::GetEnv() uses GetEnvironmentVariableW, which is a Windows API
to get an environment variable and is preferable over getenv().

attribute in LinkerInput to isWholeArchive and use that for deciding
whether library archives should be expanded. Implement the -all_load
option of the Darwin linker using this flag and drop the support for it
in GNU mode.
llvm-svn: 190275
The compiler is allowed to add a linker option starting with -?<name> to
.drectve section. If the linker can interpret -<name>, it's processed as if
there's no question mark there. If not, such option is silently ignored.
This is a COFF's feature to allow the compiler to emit new linker options
while keeping compatibility with older linkers.
llvm-svn: 189897
Before this patch, name of driver implementation is not consistent with its
option table file. Specifically, LDOptions has a different prefix than
GnuLdDriver.
This patch renames option files, so that the option files have the same prefix
as the corresponding driver files.

This changes the interface of createLinkerInput to use ErrorOr, so that
errors from the linker can be captured.
Also adds a convenience function for error strings to be returned from
file nodes.

This creates .init_array/.fini_array section for X86_64 ELF
targets and executes init/fini functions specified by the
-init/-fini options respectively.
llvm-svn: 189719
This adds an API to the LinkingContext for flavors to add Internal files
containing atoms that need to appear in the YAML output as well, when -emit-yaml
switch is used.
Flavors can add more internal files for other options that are needed.

With this patch the entry symbol is treated as an undefined symbol, to force
the resolver to resolve the entry symbol.

This completes the subsystem name parsing to support the identifiers that the
Microsoft link.exe linker supports. "windows" and "console" are left as the
first items as they are the expected common paths.

This used to be handled automagically by the option parsing library,
but after LLVM r188314, we should handle it ourselves.
No functionality change, but adds a test.
llvm-svn: 188318
Also change some local variable names: "ti" -> "context" and
"_targetInfo" -> "_context".

This patch does not change the behavior of LLD, but changes the output of the
help text. We want to show the help text with Windows style indicator rather
than Unix style indicator.
llvm-svn: 187544
This reverts commit r187390 because we should not handle argv's quotes ourselves.
In Windows, unlike Unix, quotes are not processed by the shell. Instead the C
startup routine parses it as described in
http://msdn.microsoft.com/en-us/library/a1y7w461.aspx and pass the results to
main(). So, at the time when the control reaches main(), quotes that should be
removed has already been removed.
We still need to handle quotes in the response file and in .drectve section
ourselves. That will be addressed in different patches.
llvm-svn: 187534
The /include command line option is equivalent to Unix --undefined
option, which forces the linker to resolve the given symbol name
as if it's an unresolved symbol in one of its input files. This feature
is used to link an additional object file or a shared library that no
input files refer to.
llvm-svn: 187084
This renames variable name to reflect initial undefined symbols that are
defined by the linker -u option.
This doesnot change any functionality in lld, and updates code to reflect
Nick's comment.

Users can override the default value of the dynamic linker to be set to the
one that appears in the command line. The path can even be empty!.
Added a test for the option.

Add WinLinkDriver and connect it to the existing COFF reader. Remaining
parts are still stubs, so while it can now read a COFF file, it still
cannot link or output PE/COFF files yet.

to the list of undefined atoms.
The processing of undefined atoms from dynamic libraries is controlled by
use-shlib-undefines command line option.
This patch also adds additional command line arguments to allow/disallow
unresolved symbols from shared libraries and mimics GNU ld behavior.
llvm-svn: 179257
The major changes are:
1) LinkerOptions has been merged into TargetInfo
2) LinkerInvocation has been merged into Driver
3) Drivers no longer convert arguments into an intermediate (core) argument
list, but instead create a TargetInfo object and call setter methods on
it. This is only how in-process linking would work. That is, you can
programmatically set up a TargetInfo object which controls the linking.
4) Lots of tweaks to test suite to work with driver changes
5) Add the DarwinDriver
6) I heavily doxygen commented TargetInfo.h
Things to do after this patch is committed:
a) Consider renaming TargetInfo, given its new roll.
b) Consider pulling the list of input files out of TargetInfo. This will
enable in-process clients to create one TargetInfo the re-use it with
different input file lists.
c) Work out a way for Drivers to format the warnings and error done in
core linking.
llvm-svn: 178776
This removes Target and moves the functionality it had over to TargetInfo.
This also simplifies LinkerInput by removing the InputKind. This will be handled elsewhere.
llvm-svn: 174589
I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

the keyword.
If anyone cares deeply about the final optimizations with GCC, we might
want to add a version test to the LLVM definition, but I'm perfectly
happy with this just only firing under Clang and modern MSVC builds.
llvm-svn: 172898
There is no way to test this at the moment because the options are not
processed until the link starts, and we can't pass an empty file.
llvm-svn: 171910
This includes selecting which driver to emulate, option parsing, invocation
building, and running the link. This currently only supports a very basic
subset of ld for x86_64-linux.
lld -flavor ld obj.o -o obj
or symlink lld as (ld , link, ld64, core) to get the desired behavior without
-flavor.
