Hi,
I noticed that the code of the ARM/Thumb executables is not very different.
Some online documentation on ARM claim that they achieve a 30% code size
reduction when they generate thumb code. I compiled some programs using
gcc (cross compiled version) and there was a reduction of about 5-10% atmost.
Is this because gcc code generation for the ARM is not as good as other
compilers?
