I am using the following command sde-g++ -v -mtune=r2k -T ph.ld -O2
GCD.cpp -o GCD.bin, and I am having no success but if I remove
iostream the compile will run fine, the problem is that I do not
believe its creating the right mips-elf file when I look at the
assembler code from the disassembler list the code doesn't appear to
work right, following the code line by line I see mistakes that will
eventually lead to infinite loops and the c++ code I wrote is fine it
compiles in DEV C++ and runs fine but the code produced by g++ that I
am testing on my processor more than likly will not work because I
don't believe it was done correctly by the linker and compiler and I
believe its because I have to remove iostream. What do you guys
think? The Disassemebleed code is shown below, with the compile
commands I used to get the result.
sde-g++ -mtune=r2k -T ph.ld -O2 GCD.cpp -o GCD.bin
sde-objdump --disassemble --line-numbers --source GCD.bin >
disassemble.list
