Hi, friends ! I apologize, that question might not be new to you. I didn't find the information in the gcc docs. The question is: What registers need to be saved in an assembler subroutine called from gcc ? I'm using gcc 2.3.1 on an Intel 486 (SCO ODT 2.0). Where do I derive this information from, where or how do I find it generally (for other target machines) ? Thank you very much.
