Next, perform Updating GNU ld Linker and Modifing BREW SDK include file.

GNU ld linker (arm-elf-ld.exe) in GNUARM 4.1.1 is version 2.1.7. This version does not support both "--emit-relocs" and "--gc-sections" options on at the same time.

The following is a brief explanation about the two options.

"--emit-relocs" option outputs the relocation table information. BREW Elf2Mod Tool needs this information to convert an elf file into a mod file.

"--gc-sections" option deletes unsed functions to make the size of a linked module smaller.

This issue can be solved by replacing the arm-elf-ld.exe with patched GNU ld 2.19.1 (execution file).

(*) Exisisting linker is unable to emit position independent veneer codes (pic-veneer) when arm/thumb interwoking (in particular thumb mode to arm mode). The bug is also fixed in the patched edition.

	In the latest YAGARTO
	The bug is fixed at binutils 2.20 in the latest YAGARTO (20091223) (2009/12/24 now). However, there are some issues with math functions, and we don't recommend to use it until they are resolved.

When using BREW SDK 3.1.2 or below, you have to update the the BREW header file "sdk\inc\AEESource.h" as follows:

#define DECLARE_IGETLINE(iname)\
   int32  (*GetLine)  (iname *po, GetLine *pgl, int32 nTypeEOL);\
   void   (*UngetLine)(iname *po, int32 nLenUnused)

#define INHERIT_IGetline(iname)\
   INHERIT_IPeek(iname);\
   int32  (*GetLine)  (iname *po, GetLine *pgl, int32 nTypeEOL);\
   void   (*UngetLine)(iname *po, int32 nLenUnused)

#define DECLARE_IGETLINE(iname)\
   int32  (*GetLine)  (iname *po, struct GetLine *pgl, int32 nTypeEOL);\
   void   (*UngetLine)(iname *po, int32 nLenUnused)

#define INHERIT_IGetline(iname)\
   INHERIT_IPeek(iname);\
   int32  (*GetLine)  (iname *po, struct GetLine *pgl, int32 nTypeEOL);\
   void   (*UngetLine)(iname *po, int32 nLenUnused)

When using BREW SDK 4.0.4 SP02, you have to update the 30th line of the BREW header file "sdk\inc\AEEOldVaList.h" as follows:

#elif defined(__GNUC__) && defined(__arm__)

#elif (0)
