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

You conclude that reentrant stack in idata more preferrable ? So, could you explain me which sense to simulate reentrant stack in idata ? Instead of simulated reentrant stack in idata can be used efficient native hardware stack (via SP and PUSH/POP instructions). Which sense in simulation ?
