Hello,
My problem is quite simple, the PPC has few conditions registers and some are
assumed to be saved over function calls (in my test case NU_Sleep()), but the
hard real time kernel do not save those (partial flags) registers.
This behaviour is perfectly documented in gcc-4.1.1/gcc/config/rs6000 line 709,
but is there a simple solution (maybe involving recompiling the compiler) to
force re-testing values after function calls?
I do remember the i386 option -mreg-alloc="dacbSDB", but it does not seem to be
supported for PPC; the best would be a compiler option to say "full CC register
clobber by function call".
Thanks for any info,
Etienne.
