Hi, i have a question about SDLD. On systems where programs are loaded inro RAM, say, MSX or ZX Spectrum or whatever else computer, there is some sense in saving RAM by making _INITIALIZED and _INITIALIZER section have the same base address. Unfortunately, that is not very easy task, because you can not put sections one after the other efficiently because of the unknown sizes of sections which land before. for example:
.area _CODE .area _INITIALIZER .area _WHATEVER and then -b _CODE=0x100 -b_INITIALIZED=l__CODE+0x100 is not working because l__CODE is only known after that linking phase. another solution adding a sommandline option into SDCC itself, that force emission of initialized variables together with labels into one single section. what do you think about this? any suggestions? ps: Not related with that problem, but another notice. SDLD linker is not too convenient for using with systems with OS, say, CP/M or MSX-DOS. It does not leave any information in the IHX file itself, that allow to produce executables rather than ROM dumps. However, IHX format allows to add comments and thus extensions, so maybe it is an easy way to emit info about sections into it?
