Subject: tree-pass.h (TDF_EH): Define.
X-Git-Tag: releases/gcc-4.5.0~4436
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cae63f886fb819cd96eafb32964949bc8d6e9a4f;p=thirdparty%2Fgcc.git

tree-pass.h (TDF_EH): Define.


	* tree-pass.h (TDF_EH): Define.
	* gimple-pretty-print.c (dump_gimple_stmt): If FLAGS
	contains TDF_EH, print the EH region number holding GS.
	* tree-dump.c (dump_options): Add "eh".
	* doc/invoke.texi: Document it.
