Too bad :( I had great confidence in Hercules emulator.
This is from official Hercules FAQ:
``The following standard feature has been partially implemented:
* Binary Floating-Point instructions ''
I am playing with "-msoft-float" gcc option which
disables hawdware floating-piont instructions and
uses glibc's ones instead but I get the following error:
/tmp/ccOWrBZJ.o: In function `main':
/tmp/ccOWrBZJ.o(.text+0x40): undefined reference to `__extendsfdf2'
collect2: ld returned 1 exit status
Doeas somebody know in what library
`__extendsfdf2' is?
Thanks in advance,
Nicolai
