Hi,
I'm currently maintaining a gcc toolchain for ARM target, meant
primarily for developing homebrew software for Nintendo GBA and GamePark
GP32. Recently I have been researching adding the Nintendo DS, which has
an arm7tdmi and an arm946e-s but I'm not entirely sure of the correct
options to use for the arm9.
Compiling code with -march-armv5te results in link errors of the form
ERROR: .o uses VFP instructions, whereas .elf does not
I found these threads which seem to be relevant
http://sourceware.org/ml/crossgcc/2004-10/msg00048.html
http://sourceware.org/ml/crossgcc/2004-09/msg00055.html
does anyone know if armv5te is appropriate for 946e-s and, if so, what
the best approach would be for constructing a toolchain which can build
code for arm7tdmi, arm946e-s, and arm920t?
Dave
