Rui Ueyama 8db1eddc07 Make Driver::link and LinkingContext::validate return true on success.
This patch inverts the return value of these functions, so that they return
"true" on success and "false" on failure. The meaning of boolean return value
was mixed in LLD; for example, InputGraph::validate() returns true on success.
With this patch they'll become consistent.

Rui Ueyama 0e08d7757b [PECOFF] Ignore /pdbaltpath option.
/PDBALTPATH:<path> is an option to embed a different path for the PDB file to
the binary than the actual PDB file location. Because we don't support PDB
file, we'll just ignore the option for now.

llvm-svn: 191254
2013-09-24 00:16:27 +00:00
Rui Ueyama 456740c740 [PECOFF] Do not allow space to separate command line option and its value.
We used to support both Windows and Unix style command line options. In Windows
style, an option and its value are separated by ":" (colon). In Unix, separator
is a space. Accepting both styles were convenient, but we can no longer allow
Unix style because I found that can be ambiguous.

For example, /nodefaultlib option takes an optional argument. In Windows style
it's going to be something like "/nodefaultlib:foo". There's no ambiguity what
"foo" means. However, if the option is "/nodefaultlib foo", "foo" can be
interpreted either an optional argument for "/nodefaultlib" or an input file
"foo.obj". We should just stop accepting the non-standard command line style.

2013-09-23 23:51:31 +00:00
Rui Ueyama 5c59ab7f3d [PECOFF] Ignore /delay and /delayload options.
These options are to enable DLL delay loading. If enabled, DLL is loaded
at run time by a helper routine when a function in the DLL is actually called
for the first time, instead of making the Windows loader to load all DLLs at
startup time. This should shorten startup delay if an executable have many
imported symbols.

The linker needs to create a "delayed import table" and link delayimp.lib in
which helper functions are defined to support the feature.

For now, we just ignore the options, so that the linker does not complain when
it sees these options. We want to support them in the future.

Shankar Easwaran 7915ff34b7 [lld][LinkingContext][ELF] Allow different output file types.
This adds an option --output-filetype that can be set to either
YAML/Native(case insensitive). The linker would create the outputs

Changes all the tests to use the new option.

Rui Ueyama 508939428d [PECOFF] Ignore /incremental option.
/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.

Rui Ueyama 91a95a590a [PECOFF] Ignore /errorReport command line option.
/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.

Rui Ueyama 3adc09e9fc Revert "[PECOFF][Driver] Remove quotes from command line arguments."
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.

tests for the driver.

2013-07-24 23:18:02 +00:00
Rui Ueyama fd50283c3c [PECOFF] Add /include command line option.
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.
