Use the web interface provided at: http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001142 --- Comment #18 from Sergei Gavrikov 2011-02-14 22:02:17 GMT --- (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 #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 #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 :-) -- Configure bugmail: http://bugs.ecos.sourceware.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
