Subject: Fix uninitialized field in expand_operand.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=55c7ffae7021367df36588d7991a1fb0f870e2c6;p=gcc.git

Fix uninitialized field in expand_operand.

Commit g:f96bf49a0 added the target field to expand_operand.
But it leaves it uninitialized when doing a full initialization
inside create_expand_operand.  This fixes the problem and improves
the code generation inside create_expand_operand too.

ChangeLog:
* optabs.h (create_expand_operand): Initialize target field also.
