Hi
Can somebody tell me, what is the right way to make a soft float
toolchain. I tried with crosstool with different flags for configure
and gcc, but the resulting binaries still contains the FP instructions,
like swc1.
I used --with-float=soft and --nfp for gcc configure,
--without-fp for glibc configure, and compiled glibc
with -msoft-float flag.
Am I missing something, or am I using the wrong flags?
GCC: 3.3.5
GLIBC: 2.3.5
BINUTILS: 2.15
On gcc 3.3.x --with-float=soft does nothing. If you are using a MIPS32
ISA processor you can configure it with --target=mipsisa32[el]-linux to
get soft float and MIPS32 ISA by default.
But even better would be to use gcc 3.4.x or 4.0.x where
--with-float=soft works. I would also recommend binutils 2.16.1 or
above as there are some severe bugs in the mips linker in earlier versions.
