Subject: C++, testsuite: Adjust pure-virtual1.C options for Darwin.
X-Git-Tag: basepoints/gcc-12~5934
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e0e546635a307c2a0a2c6c909e92dce3dfc967ff;p=thirdparty%2Fgcc.git

C++, testsuite: Adjust pure-virtual1.C options for Darwin.

Darwin's static linker expects, by default, that all linkage will
be satisfied (even for weak items).  This allows the two-level
namespace to work even for weak cases.

However, there's an option to make it behave in a similar manner
to ELF.  This is needed for the pure-virtual1.C testcase to pass
on Darwin.

gcc/testsuite/ChangeLog:

	* g++.dg/abi/pure-virtual1.C: Add dynamic_lookup option
	for Darwin.
