Strace port to SuperH SH5

[Thomas,Stephen]

Hi Roland,

Thanks for your mail. Re. the setbpt etc. functions, I realize this is no longer used in linux, but is it still used on other systems? Or is it now completely obselete? I notice that most architecures still implement these. So is there any value in leaving this code there? (not that I have the ability to build or test for anything other than linux!). The SHmedia port uses the new mechanism (via arg0_offset etc.), & I have verified that the '-f' option works OK. 

Re. the syscall numbers in syscallent.h, SHmedia linux is still only V2.4, & likely to remain that way for some time. Can we send an update for V2.5 later please?

Thanks,

Steve Thomas

The old `setbpt' function that edits code is no longer used on Linux.  The `setbpt' function earlier in util.c is what is used now.  If your definitions of arg[01]_offset and restore_arg0 are correct and strace -f is working for you, that's all that needs to be done.  The additions to the other util.c code and the data structure changes are not necessary. Can you send me a (tested) version of the patch without those?

If shmedia has assigned numbers for the various new system calls in Linux 2.5, please add those to the table as well.  The linux/syscallent.h (i386) file has a pretty complete list now, so you can see which are printargs and which sys_foo.


Thanks,
Roland
