Hi there,
I am using gcc-3.3.3-glibc-2.3.2-linux-2.6.8 from crosstool-0.28-rc37 for ARM9.
export KERNELCONFIG=`pwd`/arm.config
export TARGET=arm-softfloat-linux-gnu
export TARGET_CFLAGS="-O"
export GCC_EXTRA_CONFIG="--with-float=soft"
export GLIBC_EXTRA_CONFIG="--without-fp"
export BINUTILS_DIR=binutils-2.15
export GCC_DIR=gcc-3.3.3
export GLIBC_DIR=glibc-2.3.2
export LINUX_DIR=linux-2.6.8
export GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.2
Do I have to pass -msoft-float when compiling applications with floating point
operations? Or is this flag on by default?
How do I know if floating point operations are realy handle by the softfloat
functions and not by the kernel emulator?
