Thanks for the patch.  In the future, please provide the ChangeLog entry
separately in the body of the message, rather than as part of the patch
itself.

The ChangeLog entry should say what is being changed in each file.  It
should look something like this:

2009-03-12  Jing Yu  <jingyu@google.com>

	PR middle-end/39378
	* function.h (struct rtl): Move is_thunk field from here...
	(struct function): ...to here.
	* cp/method.c (use_thunk): Change is_thunk from crtl to cfun.
	* varasm.c (assemble_start_function): Change is_thunk from crtl to
	cfun.
	* config/alpha/alpha.c (alpha_sa_mask): Change is_thunk from
	crtl to cfun.
	(alpha_does_function_need_gp, alpha_start_function): Likewise.
	(alpha_output_function_end_prologue): Likewise.
	(alpha_end_function, alpha_output_mi_thunk_osf): Likewise.
	* config/rs6000/rs6000.c (rs6000_ra_ever_killed): Likewise.
	(rs6000_output_function_epilogue): Likewise.
	* config/arm/arm.h (ARM_DECLARE_FUNCTION_NAME): Likewise.

Note that thunk10.C should not be mentioned in this ChangeLog file; it
should be in testsuite/ChangeLog, as you have done separately.

Please add a blank line between your name and the start of ChangeLog
entry.


This is OK with the adjusted ChangeLog entries.

Thanks.
