>Description:
File attached fails to compile as c++ code with optimization. Errors produced:
convert.cc: In function `long int f(float)':
convert.cc:4: output number 0 not directly addressable
convert.cc:4: inconsistent operand constraints in an `asm'

This file do compiles, however, without optimization. It compiles as 'C' code with any optimization.
Original code is extracted from KDE libs.


>How-To-Repeat:
Not compiled:
gcc -O -c convert.cc
(as well as -O1, -O2, -O3)Do compiled:
gcc -c convert.cc
gcc -x c -O3 convert.cc
(as C code it compiles with any optimization)
