Hi all,
On my SOC(which uses cortex-a8 architecture) VFP coprocessor is not
working properly, we are using codesourcery's(2010 lite
version.gcc-4.4.1) tool chain,
Now my question is While compiling any application ,what flags we
should avoid so that any hard float instructions are not included?
When these instructions are used?
"gcc/config/arm/libunwind.S"
"gcc/config/arm/pr-support.c"
"gcc/config/arm/unwind-arm.c"
