Nick Kledzik 0932c004a9 [mach-o] Add support for -mllvm to darwin driver
llvm-svn: 191594
2013-09-28 00:29:33 +00:00
Nick Kledzik 473933b89f [mach-o] switch to use llvm::MachO:: constants
Stop using some locally defined mach-o constants.

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.

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
associated with the type specified by the user.

Changes all the tests to use the new option.

Rui Ueyama eb0434e9ae Fallback to the default stringize function to show some meaningful error message.
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.

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.

Rui Ueyama 98896ed1b5 [PECOFF] Add a field for machine type to PECOFFLinkingContext.
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.

in GNU mode.

Rui Ueyama 959aebf873 [PECOFF] Ignore options starting with -?
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.

Rui Ueyama 8ccf6da056 Rename *Options.td -> <flavor>Options.td.
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.
