IFL not working correctly #210

Closed orlof closed 11 years ago

orlof commented 11 years ago

Platform: Windows 7 Version: http://bb.dcputoolcha.in/builds/windows/dists/dcputoolchain-windows--791381db25a032a622ed91e1cc5e55024946a098.exe

Following test program's logic is IF 0<12: a=10. When run with dtemu it skips the SET as can be seen from the debug log.

For me it seems that the literal value "12" has been changed to 0x0000.

IFL [val], 12
  SET A, 10
:halt
  SET PC, halt

:val DAT 0

...and here is the same thing run with dtdb. In this memory dump the literal value seels to be ok (000C).
