So that the LLD won't print error message saying that it couldn't find
/implib or /safeseh files.

Also slightly reduces PECOFFLinkingContext's memory footprint (~128B).

This reverts commit r194551 because it broke the buildbot.

no functionality change.

These fields are for /align option. Section alignment can be set per-section
basis with /section option too. In order to avoid name conflicts, rename the
existing identifiers to become more specific. No functionality change.

llvm-svn: 194160

/section command line option is to set/reset attributes of the Characteristics
field in the section header. You can set non-default values with this option.
You can make .data section executable with this, for example.

This patch implements the parser of the command line option. The code to use
the parsed values will be committed in a separate patch.

I'm not sure if it is really an alias for /nodefaultlib, but I can say that
they are at least similar. Making it an alias would be better than ignoring it.

/defaultlib options can be specified implicitly via the .drectve section, and
it's pretty common that multiple object files add the same library, such as
user32.lib, to the input. We shouldn't add the same library multiple times.

llvm-svn: 194129

msvcrt.lib contains "/disallowlib" command line option in its .drectve section.
I couldn't spot any documentation for the option. Ignore it for now so that we
can link the library without error.

llvm-svn: 194114

Errors in .drectve section were silently ignored. This patch fixes the issue.

Enable this for the following flavors

a) core
b) gnu
c) darwin

Its disabled for the flavor PECOFF. Convenient markers are added with FIXME
comments in the Driver that would be removed and code removed from each flavor.

intended for debugging and diagnostic output), just inspect the spelling
to check for specific prefixes in drectve section flags.

In addition to being significantly cheaper and not relying on
a debugging interface, this also avoids creating a temporary string and
binding it to StringRef variable. We then went on to access it after the
memory had been deallocated.

This bug too was caught by ASan. I love ASan so much. =]

/merge:<from>=<to> option makes the linker to combine "from" section to "to"
section. This patch is to parse the option. The actual feature will be
implemented in a subsequent patch.

We really need a test for the manifest file output, but because it depends
on external commands (CVTRES.EXE and RC.EXE), it's not very easy to write it.

The internal byte array of the SmallString filled by createTemporaryFile() is
not guaranteed to be NUL-terminated. We need to call c_str() to handle it
safely.

The patch have completely broken COFF port and disabled many tests.
This also reverts r193302 (comment fix).

llvm-svn: 193362

Easier to add new options such as -version, and easy to parse.

Now displays a help message with -help

llvm-svn: 193301

Disable tests to be run with REQUIRES: disable. Note disable is not added to the
config by the test runner Mkaefiles, so essentially disables the test.
