#154237 - Correct ! Responding to: ???'s previous message |
The code reveals behaviour of the compiler - not the MCU.
And Yes, to get size of a register we propably need ASM. For example one could assign a zero to a register and then count the number of times it takes to increment it to get it's value back to zero. I needed the code when we were VERY frequently porting a program (containing embedded SQL) between Digital Alpha, HP-UX and Windows platforms. Since the Ingres sqlc is really stoopid - this was the only cure.... and we tried... |

| C is not that portable! | 01/01/70 00:00 | |
| thanks but could u clarify | 01/01/70 00:00 | |
| I think you missed the point | 01/01/70 00:00 | |

| I found the solution, Andy , Neil please comment | 01/01/70 00:00 | |
| Great! Now do it in C | 01/01/70 00:00 | |
| Same logic for C and asm | 01/01/70 00:00 | |
| No, it isn't. | 01/01/70 00:00 | |
| What would be the point? | 01/01/70 00:00 | |
| It is worse than that | 01/01/70 00:00 | |
| the whole question is silly | 01/01/70 00:00 | |
| It can even get this silly... | 01/01/70 00:00 | |
