I have a need for making a buffer, the size of which is as large as possible. I know how to do that in assembler; however, not in C. Two ways would work: 1) a pointer to the end of used xdata 2) an array my_array[MAX] I much prefer method #1, but any method that will give me the desired result will be appreciated. Thanks, Erik
Hi eric, as far as I know reordering only applies to modules, compiled by C51. The ORDER-directive turn off reordering:
#pragma ORDER
"but I guess you can assume this" That's the problem, I will not make something that may fall apart when Keil releases a new version.
Voilà one Reason, why we still use C51 V5.10. We are afraid of surprises. By the way: The assumption is definitely true for the combintion of partial code-segments (i.e. constant data in code). This is a feature on which Keil itself relies with their variable initialization routine ?C_START: a trailing zero linked at the end of ?C_INITSEG stops the initialization. It is also documented, that the customized STARTUP.A51's object file must be the last object file to be specified in the command-line. By the way. I think I remember that you've said, you have an assebler-solution to your problem. But to me this seems to be a linker problem, rather than a translator problem. So: How do you do it with the assembler? Norbert.
