Hi All,
I am trying to build the glibc
that uses softfloat and I need some
guidance on the following matter.
1.for a processor who doesn't have Floating
Point Unit (H/w support) , how the software floating point
emulation can (glibc/soft-fp) be build in
glibc.
I mean, how to
configure/make glibc for this.
2. In this situation (configuring
glibc with software floating support) , what are the minimum files
will be required to be implemented ( e.g., the floating-point environment
routines whose names start with 'f' like sysdeps/_Target_/fpu/feclrexct.c,
fedisblxcpt.c..etc.) and assuming that I will be using standard implementations
for all math operations i.e., libm-ieee754 routines.
3. If these files are required and
if target doesn't have Floating Point Status Register (unlike to
ARM who has FPSR register ), what could be done to implement those
routines which uses FPSR.
Thanks in advance.
