Hi All,
I wonder whether the "arm-linux-" toolchains recommend by the uClinux website
can be used for ARM uClinux world.
The compiler library "libgcc.a" will be an issue.
Since XIP code is must for uClinux, the "libgcc.a" must be produced by the XIP
compiling flags.
For ARM, it will be "-fpic -msingle-pic-base".
By objdump inspecting, I found the libgcc.a of the "arm-linux" toolchains on
the uClinux website is not compilied by the options.
When the program calls the functions of libgcc.a, it will be broken in some
cases.
The easy way to test is to do the "long long" variable division.
However, i seldom heard people complain about their toolchains.
Why? Or my understanding is wrong?
Doesn't other architecture have the same issue?
Best Regards,
KJ
