Upgrading a cross compiler from GCC 3.4.6 to 4.1.1

[Rohit Arul Raj]

Hi all,

I am upgrading a cross compiler from gcc 3.4.6 to gcc 4.1.1.

i just want to confirm whether the poisoned  macro
FUNCTION_ARG_PASS_BY_REFERENCE in target.h is replaced by the target
hook in target.c as TARGET_PASS_BY_REFERENCE.

Is there any log file other than ChangeLog which keeps the list of
macros replaced.

Regards,
Rohit
