Subject: except.c (expand_start_all_catch): If the machine needs a nonlocal_goto_receiver...
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05f5b2cdf97d10cd4448a59c7d6c1b92416c8fcc;p=platform%2Fupstream%2Fgcc.git

except.c (expand_start_all_catch): If the machine needs a nonlocal_goto_receiver...

	* except.c (expand_start_all_catch): If the machine needs a
	nonlocal_goto_receiver, add one at the start of the exception
	handler.
	(expand_leftover_cleanups): Likewise.
Potential fix for eh on alpha, rs6000, and hppa.
