Subject: Fix block index check in insert_updated_phi_nodes_for
X-Git-Tag: basepoints/gcc-16~9272
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bf10f0db20db1598157505b373098bc93c66b915;p=thirdparty%2Fgcc.git

Fix block index check in insert_updated_phi_nodes_for

This replaces a >= 0 block index check with the appropriate NUM_FIXED_BLOCKs,
the check is from times ENTRY_BLOCK was negative.

	* tree-into-ssa.cc (insert_updated_phi_nodes_for): Fix block
	index check.
