------- Comment #28 from bergner at vnet dot ibm dot com 2006-11-29 20:11 -------
Another problem with the current patch, is we get one testsuite regression
(gfortran.fortran-torture/compile/defined_type_2.f90 at -O1). For this simple
testcase, we end up generating bad assembler:
mr 9,sfp
instead of:
mr 9,1
For some reason, the stack frame pseudo isn't reloaded correctly and we spit
out the "sfp" text instead of the correct register number.
