David Majnemer	259d91a99b	COFF: Don't oversize COMMON symbols when targeting BFD ld ... COFF normally doesn't allow us to describe the alignment of COMMON symbols. It turns out that most linkers use the symbol size as a hint as to how aligned the symbol should be. However the BFD folks have added a .drectve command, which we now support as of r219229, that allows us to specify the alignment precisely. With this in mind, stop rounding sizes up. llvm-svn: 219281	2014-10-08 06:38:53 +00:00
Saleem Abdulrasool	f21ec83434	MC: add support for -aligncomm GNU extension ... The GNU linker supports an -aligncomm directive that allows for power-of-2 alignment of common data. Add support to emit this directive. llvm-svn: 219229	2014-10-07 19:37:57 +00:00
