Hi
I am trying to build MIPS toolchain with soft float,
without success :-(
Using crosstoll-0.35 (tried with 0.38 too) with various
combination of flags in mipsel.dat, like:
----------------------------------------------------------
TARGET_CFLAGS="-O2 -finline-limit=10000 -msoft-float"
GCC_EXTRA_CONFIG="--with-float=soft --nfp"
GLIBC_EXTRA_CONFIG="--without-fp"
----------------------------------------------------------
If I do:
mipsel-linux-objdump libgcc.a | grep swc1 I get:
24: e7b40028 swc1 $f20,40(sp)
28: e7b5002c swc1 $f21,44(sp)
3c: e7b60030 swc1 $f22,48(sp)
40: e7b70034 swc1 $f23,52(sp)
14: e7b40028 swc1 $f20,40(sp)
18: e7b5002c swc1 $f21,44(sp)
....
libgcca still contains FP instructions.
Has anybody successfully build MIPS SF toolchain?
BR,
Matej
