Erich Keane	7544967108	Add support for ObjectFormat to TargetSpecificAttr ... Looking through the code, I saw a FIXME on IFunc to switch it to a target specific attribute. In looking through it, i saw that the no-longer-appropriately-named TargetArch didn't support ObjectFormat checking. This patch changes the name of TargetArch to TargetSpecific (since it checks much more than just Arch), makes "Arch" optional, adds support for ObjectFormat, better documents the TargetSpecific type, and changes IFunc over to a TargetSpecificAttr.

Serge Pavlov	947719bed1	Process attributes 'ifunc' and 'alias' when checking for redefinition ... These attributes effectively turn a non-defining declaration into a definition, so the case when the declaration already has a body must be diagnosed properly.

Benjamin Kramer	b8b2f3f6c8	Don't clutter the test directory with temporary IR files. ... -emit-llvm emits a file, -emit-llvm-only doesn't. llvm-svn: 265926	2016-04-11 10:16:37 +00:00
Dmitry Polukhin	85eda12d09	[GCC] Attribute ifunc support in clang ... This patch add support for GCC attribute((ifunc("resolver"))) for targets that use ELF as object file format.
