Maybe "complexity" starts in the target's config, as that CDL booldata (for the section's name) was set as a string default_value { "foo" } In fact then in the most we need to manage the labels and addresses (!strings). If we avoid the first stringification, i.e. define in CDL default_value foo then we will have destringified things in pkgconf/* like #define CYGHWR_~~~_FOO foo #define CYGHWR_~~~_FOO_foo And CYGHWR_~~~_...FOO is ready to use in .ld, .ldi, .h files, is it not? Well, I call the LWIP's MEM_SECTION macro. If it make life easier, I would prefer to add 1 "extra" line in lwipopts.h #define STRINGIFY(x) #x #define MEM_SECTION CYGBLD_ATTRIB_SECTION(STRINFIFY(CYGHWR_~~~_xxxFOO)) It seems to me this would let us do not use complex de-stringify macros in arch. ld script. -- 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.
