Description :
Not sure whether this is a real issue and how much is can be changed, but slicing is very slow with this command and program:
i=s.20000836.1.c ~/ppc/bin/toplevel.opt -val-signed-overflow-alarms i -cpp-command "gcc -m32 -C -E -D__FRAMAC -I. -ICSMITH/runtime " -slice-calls Frama_C_show_each -slevel 5000 -slevel-function crc32_gentab:0 -then-on 'Slicing export' -print -ocode s.c -kernel-debug 1
The -kernel-debug 1 is to get a backtrace when pressing ctrl-C:
