We have Lattice 3.1 and have applied the two fixes to the
compiler and libraries.
A simple statement such as
printf("%f\n",4.0/2.0);
does not give the expected results when compiled
"lc -f -Lf blah", but does when compiled "lc -Lm blah".
The problem certainly appears to be a bug in the constant
expression evaluation section of the compiler, (it does
not realize it is working with motorola ffp format?) since
when an intermediate assignment is done, and the compiler
is forced to generate actual multiply or divide function
calls, the correct output is generated. eg.
printf("%f\n",4.0/(x=2.0));/* where x is "float" or "double" */
It is possible to work around this bug, but makes for interesting
debugging when using #define's.
Is there a new fix to the compiler?
