Populated. For reference. Original report effectively said "it's CyrixInstead and ecx is 0x64616574". Note that in ASCII ecx reads "tead" or last four characters of CPU name. __ OpenSSL Project http://www.openssl.org Development Mailing List openssl-dev@openssl.org Automated List Manager majord...@openssl.org

[openssl.org #3005] Invalid cpuid on Cyrix
Hi, I got a user reporting a problem on Cyrix CPUs. The problem is that cpuid detects the rdrand instructions from intel, and then tries to use that instruction and gets an illegal instruction. /proc/cpuinfo looks like: processor : 0 vendor_id : CyrixInstead cpu family : 6 model : 2 model name : M II 3.5x Core/Bus Clock stepping: 8 cpu MHz : 233.895 fdiv_bug: no hlt_bug : no f00f_bug: no coma_bug: no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de tsc msr cx8 pge cmov mmx cyrix_arr bogomips: 467.79 clflush size: 32 cache_alignment : 32 address sizes : 32 bits physical, 32 bits virtual power management: And it has this in OPENSSL_ia32cap_P: OPENSSL_ia32cap_P[0] = 0x0080A535 OPENSSL_ia32cap_P[1] = 0x64616574 The code then sees bit 62 being on and the library tries to use the instruction.
