Subject: C-SKY: Fix missing operand when do spilt for cskyv2_addcc and cskyv2_addcc_invert.
X-Git-Tag: basepoints/gcc-14~4751
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=33b182f61280d991bd0bda33003b5ee2a16024e2;p=thirdparty%2Fgcc.git

C-SKY: Fix missing operand when do spilt for cskyv2_addcc and cskyv2_addcc_invert.

It will cause ICE when compiling the case:
gcc/testsuite/gcc.dg/params/blocksort-part.c

gcc/
	* config/csky/csky.md (cskyv2_addcc): Fix missing operand.
	(cskyv2_addcc_invert): Likewise.
