X-Git-Tag: basepoints/gcc-13~5413
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fa28520fadb9405f4387ceb419b0b7fc3ba0a61f;p=thirdparty%2Fgcc.git

ipa: do not make localaliases for target_clones [PR101261]

	PR ipa/101261

gcc/ChangeLog:

	* symtab.c (symtab_node::noninterposable_alias): Do not create
	  local aliases for target_clone functions as the clonning pass
	  rejects aliases.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr101261.c: New test.
