Subject: pragma: respect pragma in lambda functions
X-Git-Tag: upstream/12.2.0~2679
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5b8f5a50a93c5fd44fa1ecb6f431fee1df267571;p=platform%2Fupstream%2Fgcc.git

pragma: respect pragma in lambda functions

In g:01ad8c54fdca we started supporting target pragma changes
that are primarily caused by optimization option. The same can happen
in the opposite way and we need to check for changes both
in optimization_current_node and target_option_current_node.

	PR c++/103696

gcc/ChangeLog:

	* attribs.c (decl_attributes): Check if
	target_option_current_node is changed.

gcc/testsuite/ChangeLog:

	* g++.target/i386/pr103696.C: New test.
