C51 v6.03+; uVision v2.07+ I want to build a Project with some files using the SMALL model, but most using LARGE. If I select LARGE in the Target options, and specify SMALL in the C51 'Misc Controls' where required, or use a #pragma in the file itself, I get a fatal Compiler error:
RESPECIFIED OR CONFLICTING CONTROL
L14: INCOMPATIBLE MEMORY MODEL
This looks right, however, remember that the C51 compiler can pass arguments in registers! So, that may affect the outcome of such an example. Sometimes, bigger example are better!!! :-) Jon
If the compiler is passing parameters in registers, surely the model has no effect on the parameters; it just affects where the compiler would have put them if it had not been able to use registers? Locals would still be affected (and reentrant stack usage, if appropriate).
Right!
