#138297 - more details Responding to: ???'s previous message |
Keil documentation said:
enum -- 8/16 bits -- 1 or 2 bytes -- -128 to +127, or -32768 to +32767
C51 now uses a char variable to represent an enum, if the enum range allows that. The SDCC documentation says nothing as usually; but as in open-source the sources ARE the documentation :-( , based on a quick peek it appears that it's wiser than Keil and attempts to use unsigned-char, char, unsigned-int, int, unsigned long, long, in this order (OK I am C-stupid so don't take this for granted). I suspect that Jez needs this for AVR-gcc, but the documentation for that one is, ehm... JW (the C-hater) |
