             Bug #: 14807
           Summary: no support for named parameters in macros
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nlewycky at google.com
                CC: llvmbugs at cs.uiuc.edu, rafael.espindola at gmail.com
    Classification: Unclassified


Testcase:

.macro foo parama=0, paramb=0
text \parama \paramb
.endm

foo X
foo X, Y
foo X, paramb=1
foo paramb=2
foo paramb=3, parama=1

should expand to:

text X 0
text X Y
text X 1
text 0 2
text 1 3

instead we error on the named parameters:

macro.s:7:14: error: unexpected token in macro instantiation
foo X, paramb=1
            ^
macro.s:8:11: error: unexpected token in macro instantiation
foo paramb=2
         ^
macro.s:9:11: error: unexpected token in macro instantiation
foo paramb=3, parama=1
         ^
