Preston Gurd	ba1ce20a7b	Support default parameters/arguments for assembler macros. ... This patch is based on the one by PaX Team. Patch by Andy Zhang! llvm-svn: 164246	2012-09-19 20:29:04 +00:00
Jim Grosbach	51fff56d58	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 llvm-svn: 161002	2012-07-30 22:44:17 +00:00
Jim Grosbach	9e97ef84db	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 llvm-svn: 154863	2012-04-16 21:18:49 +00:00
Jim Grosbach	138c2143c3	MC asm parser macro argument count was wrong when empty. ... evaluated to '1' when the argument list was empty (should be '0'). rdar://11057257 llvm-svn: 152967	2012-03-17 00:11:42 +00:00
