[Bug gas/669] New: Macro Expansion is broken

[mcvick_e at iname dot com]

During a regression build suite (since migrating from 2.14), it was found that 
the macro expansion within gas is not working properly.  The reason being is 
whitespace.

We have a number of assembly source files that get pre-processed by the GCC 
compiler, and it substitutes some #define references into our assembly source 
code.  The assembly is then passed through to gas, and compiled into object 
code.


The error occurs with the following example:

------ source example ------
        .macro  LADDR reg,sym
        lis     \reg,(\sym)@ha
        addi    \reg,\reg,(\sym)@l
        .endm

        LADDR r3, ((((((0x00380000 + 4096) + 256) + 256) + 256) + 49152) + 4096)

------ end source example -------

This same exact code will assemble flawlessly under binutils 2.14
