Dear Jean-Christophe PLAGNIOL-VILLARD,
In message 20090712120655.GA21713@game.jcrosoft.org you wrote:
It will hush up the current errors, but that's actually a bad thing here - the errors are an indication that Jean-Christophe's patch might not be working as it is supposed to.
They do fix what they are suppose to , fix FPU and EABI problem which was re-introduce by the 64 bit mtd support here the problem is different you try to div64 which is not supported on arm you do need to do_div
What do you mean - not supported by ARM? Of course ARM supports 64 bit division.
Compiling this little test code:
long long div(long long x, long long y) { return x / y; }
will result in a call to __aeabi_ldivmod using an EABI compliant version of GCC, resp. to __divdi3 using an older compiler. So GCC knows how to handle this, and it provides adequate functions to do it.
please apply this patch so I'll be able to send a pull request with the arm specific part and other patch be go in vacancy for one week this night
I really hesitate to do that. It seems that not using the compiler provided library is not such a clever thing to do. The compile writes probably know better what a specific version of GCC needs that anybody else.
Best regards,
Wolfgang Denk
