Rui Ueyama 81d0d29639 Remove hard-coded leading underscore from entry symbol.
llvm-svn: 190586
2013-09-12 05:09:01 +00:00
Rui Ueyama 1e6af15388 Do not hard code the leading underscore.
Mangling scheme varies on platform, and prepending an underscore is valid only
on 32-bit x86. Added a method to mangle name to PECOFFLinkingContext and use
it to avoid hard coding mangled names.

Rui Ueyama 5c532370d5 Use llvm::sys::Process::GetEnv() instead of ::getenv().
Process::GetEnv() uses GetEnvironmentVariableW, which is a Windows API
to get an environment variable and is preferable over getenv().

Joerg Sonnenberger bd25241e0e Drop the context forceLoadAllArchives() support. Rename the isForceLoad
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.

Shankar Easwaran 8c705690ab [lld][ELF] Differentiate between Note sections(RW/RO)

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.
