[Bug c/26607] New: Illegal inlined assembler on config/rs6000/darwin-ldouble.c

[edmar at freescale dot com]

Gcc cannot process in-lined assembler, when configured for powerpc-gnuspe
target (Note: that target does not have float point registers, but it has float
point sinstructions that operates on the general purpose registers).

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-03-08 19:11 -------
This was caused by the 128bit long doubles patches (well really caused by a
secondary patch to work around a code gen issue).

I\x7f should had looked into this one.  This is what I was afraid of when this
idea 128bits long double went it.  It was not the optimization which I thought
was applied but instead just the compiling of darwin-ldouble.c on
powerpc-linux-gnuspe which caused it:

                    Alan Modra  <amodra@bigpond.net.au>

        * config/rs6000/t-ppccomm (LIB2FUNCS_EXTRA): Add darwin-ldouble.c.
