Subject: Work around gcc10 FAIL: S-records with constructors
X-Git-Tag: binutils-2_33~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fdbc0dd57d84d6d57909be2f67c502cebc218fbc;p=external%2Fbinutils.git

Work around gcc10 FAIL: S-records with constructors

gcc10 on x86_64 and powerpc64le recognises that the loop in
Foo::operator= can be turned into a call to memmove, which then
results in an undefined symbol when linking.  Avoid that by making the
loop smaller.

	* testsuite/ld-srec/sr3.cc (FOO_MSG_LEN): Set to 4.

(cherry picked from commit a13ba30840ba7a8450dcb4edd356de61fcb89130)
