mips optimization

[<reedkotler at hotmail dot com>]

i'm using a mips iv chip but the os only supports 32 bit.

 

i usually then back off to -mips2 and -mcpu=5000 or such.

 

i'm trying to generate 32 bit code but allow for instructions

like MADD to be used.

 

i've done this before but now can't seem to get the compiler

to generate the MADD unless i go to mips 4, but then it generates

the 64 bit divide instruction which crashes the target.

 

any ideas?

 

has something changed recently in the compiler in this respect.

 

tia.
