hellow everyone! i am beginner about valgrind, but i need it for performance tunning of my hardware it is cpu infomation of my hardware ============== root@20:~# cat /proc/cpuinfo Processor : ARM926EJ-S rev 5 (v5l) BogoMIPS : 215.44 Features : swp half thumb fastmult edsp java CPU implementer : 0x41 CPU architecture: 5TEJ CPU variant : 0x0 CPU part : 0x926 CPU revision : 5 Hardware : DaVinci DM36x IPNC Revision : 0000 Serial : 0000000000000000 =============== is it possible to port the valgrind to my hardware? i am afraid the valgrind don't support ARMv5 : ( previously thanks~ |

The valgrind developers have decided that armv5 is not worth the trouble.
In particular, armv5 lacks reasonable hardware support for threads.
Threads can be made to work on armv5, but it is a *LOT* of trouble.
In the US today, low-end 7-inch Android tablets with armv7 have been
sold by reputable dealers for around $100.
About October 2011 (2.3 years ago) I contributed patches which enabled
memcheck to run on armv5te for single-threaded programs. Search the
archives of this mailing list:

versus armv7) and gdbserver/vgdb
