Hello,
I'm trying to compile our tools on an older lab system and get
Program received signal SIGILL, Illegal instruction.
0x00007ffff434c766 in rte_cpu_get_flag_enabled
(feature=feature@entry=RTE_CPUFLAG_RTM) at ../lib/eal/x86/rte_cpuflags.c:173
173 return (regs[feat->reg] >> feat->bit) & 1;
(gdb) bt

This already has been reported here

but I don't see a solution there. It just ends up asking for the line numbers.
Well, the line is
__cpuid_count(feat->leaf, feat->subleaf,
regs[RTE_REG_EAX], regs[RTE_REG_EBX],
regs[RTE_REG_ECX], regs[RTE_REG_EDX]);
/* check if the feature is enabled */
return (regs[feat->reg] >> feat->bit) & 1; ====> line 173
Maybe this should catch SIGILL?
Thanks,
Bernd
