To build the lists 1044 of constructors, all the linker has to do is catenate all the 1045 sections called <<__CTOR_LIST__>> and relocate the data 1046 contained within - exactly the operations it would peform on 1047 standard data. */ 1048#define SEC_CONSTRUCTOR 0x100 1049 1050 /* The section is a constructor, and should be placed at the 1051 end of the text, data, or bss section(?). */ 1052#define SEC_CONSTRUCTOR_TEXT 0x1100 1053#define SEC_CONSTRUCTOR_DATA 0x2100 1054#define SEC_CONSTRUCTOR_BSS 0x3100 1055 1056 /* The section has contents - a data section could be 1057 <<SEC_ALLOC>> | <<SEC_HAS_CONTENTS>>; a debug section could be 1058 <<SEC_HAS_CONTENTS>> */ 1059#define SEC_HAS_CONTENTS 0x200 1060 1061 /* An instruction to the linker to not output the section 1062 even if it has information which would normally be written. */ 1063#define SEC_NEVER_LOAD 0x400 1064 1065 /* The section is a COFF shared library section.
