Subject: complexity.cc: Add missing test variable.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fc3f28640aa9a1343ddc227c20147589a57e2f26;p=gcc.git

complexity.cc: Add missing test variable.

2014-10-23  François Dumont  <fdumont@gcc.gnu.org>

	* testsuite/25_algorithms/make_heap/complexity.cc: Add missing test
	variable.
	* testsuite/25_algorithms/sort_heap/complexity.cc: Likewise and use
	log2. Now require cmath support.
	* testsuite/25_algorithms/pop_heap/complexity.cc: Likewise and require
	normal mode.
	* testsuite/25_algorithms/push_heap/complexity.cc: Likewise.
