The Linux kernel does not support fetching or setting the values of
floating point registers with the ptrace(2) system call. This makes very
difficult to debug numerical software under Linux.
I have written patches for 2.0.30, 2.1.47 and placed it in
ftp://jl1.quim.ucm.es/pub/ramon/
The patch for 2.1.47 should work with any later kernel.
If you find any problem please let me know.
I would like to see these patches in the standard kernel.
If there is any reason why they should be improved please let me know.
Regards,
Ramon
