(In reply to comment #16 and comment #17)
Ilija, thank you for clarifications and snippets. I get it. However I
would rename the undescored macros (__CYG_USER_SECTION_*), e.g.
#define CYG_LINK_SECTION_START(_name_) __ ## _name_ ## _start
#define CYG_LINK_SECTION_END(_name_) __ ## _name_ ## _end
Variants of prefixes to discuss CYG_LINK, CYG_LOAD, and CYG_LD. That
will mean, - Use them in a linker scripts.
#define CYG_USER_SECTION_START(_name_) CYG_LINK_SECTION_START(_name_)
#define CYG_USER_SECTION_END(_name_) CYG_LINK_SECTION_END(_name_)
The USER means, - Use in a userspace code.
About duplication the declarations. As target.ld scripts ends with
#include <pkgconf/hal_arch.h>
#include CYGHWR_MEMORY_LAYOUT_LDI
We would declare USER_SECTION after that inclusion the arch's header
and that can be a place for standalone declaration:
#include <pkgconf/hal_arch.h>
#if defined(CYG_LINK_SECTION_START) && defined(CYG_LINK_SECTION_END)
#define USER_SECTION(_name_, _region_, _vma_, _lma_) \
._name_ _vma_ : _lma_ \
{ CYG_LINK_SECTION_START(_name_) = ABSOLUTE (.); \
*(._name_*) \
CYG_LINK_SECTION_END(_name_) = ABSOLUTE (.); } \
> _region_
#endif
#include CYGHWR_MEMORY_LAYOUT_LDI
So, the place to define CYG_{USER,LINK} macros would be hal_cortexm.h.
I hope that I did not "break" something again :-)
