Hello All
I am developing a quasi realtime DSP application in C++ that is to be ported later to an ARM processor. As far as i know this processor does not have an FPU. To get an estimate on the performance penalty, i tried to g++ -o MyTest MyTest.cpp -msoft-float on the development machine (Suse 9.1 proffesional) but i get a load of linker errors reporting that specific low level math instructions "can not be found"
After a search through the internet and the gcc mailing lists i found out a lot of fragmeneted information about this subject.
Could you please provide a simple walk through procedure where a "Hello
Soft Floating Point World" is compiled with -msoft-float succesfuly? (If this is possible...Or any other helpful comment on the subject?)
In case i have not looked thoroughly, could you please provide any links, books, physical places, that compiling with soft floating point is dealt with in detail?
All the best. thanOS
