DS development > Summited bug report in GCC for ARM946E-S CPU

#23044 - Shock The Dark Mage - Sat Jul 03, 2004 3:07 am

I just posted in GCC bugzilla, suggesting to implant the ARM cpu used in the Nintendo DS in GCC 3.4.0 branch.

You can follow the bug report here:

Given the use of GCC in GP32 (cpu=ARM920T) development, doesn't GCC already support ARM9? Or is ARM9E different enough to need support for a new instruction set architecture even before the DS is sold?

(aside: making sure that I click the right button)

i am pretty sure gcc does arm9. arm9 runs on the arm5 instruction set which is backwards compatible with arm4 instruction set. (arm7tdmi), there is not much difference.

-mcpu=arm9e should be sufficient to get started

devkitARM supports all options shown here

the developers will love the addition of a feature request to a bug reporting system :P

If the Bugzilla system for the GCC project is anything like the Bugzilla system for the Mozilla project, then the same database is supposed to contain both bug reports and feature requests. In bugzilla.mozilla.org, a feature request is merely a bug report with Severity: enhancement.
