Hello,
I'm going to make use of the new ABI for profiling in gcc 4.4 on ARM.
The patch posted on the linux-arm-kernel ML
http://news.gmane.org/find-root.php?group=gmane.linux.ports.arm.kernel&article=63642
seems to work, but I'd like to have an OK from the gcc people that
globbering ip is OK.
The patch is similar to the glibc patch at
http://sourceware.org/ml/libc-ports/2008-04/msg00009.html
. There ip is globbered, too.
It would be great if someone could have a look and review my change.
Best regards and thanks in advance
Uwe
