Jim Grosbach	9714644a38	Keep empty assembly macro argument values in the middle of the list. ... Empty macro arguments at the end of the list should be as-if not specified at all, but those in the middle of the list need to be kept so as not to screw up the positional numbering. E.g.: .macro foo foo_-bash___: nop .endm foo 1, 2, 3, 4 foo 1, , 3, 4 Should create two labels, "foo_1_2_3_4" and "foo_1__3_4". rdar://11948769 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161002 91177308-0d34-0410-b5e6-96231b3b80d8	2012-07-30 22:44:17 +00:00
Jim Grosbach	68f89a6158	MC assembly parser handling for trailing comma in macro instantiation. ... A trailing comma means no argument at all (i.e., as if the comma were not present), not an empty argument to the invokee. rdar://11252521 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154863 91177308-0d34-0410-b5e6-96231b3b80d8	2012-04-16 21:18:49 +00:00
