Test case for no-implicit-float/vararg bug
If I build the attached code with:
'clang -mno-implicit-float vartest.c -o vartest'
the double 'd' is printed as 0.0 - it's not saved into the va_list.
If I build the attached code without -mno-implicit-float:
'clang vartest.c -o vartest'
it runs as expected, and prints d: 2.300000. In this case the double has been
correctly saved into the va_list.
I would argue that this case shouldn't be affected by the no-implicit-float
flag and should succeed.</pre>
