Subject: Remove some unused poly_int variables
X-Git-Tag: basepoints/gcc-15~5834
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=46595ce72e5855189e3c60a140c3ca5aaddfb58c;p=thirdparty%2Fgcc.git

Remove some unused poly_int variables

Switching to default constructors for poly_int exposed some
unused variables that weren't previously diagnosed.

gcc/
	* dwarf2out.cc (mem_loc_descriptor): Remove unused variables.
	* tree-affine.cc (expr_to_aff_combination): Likewise.

gcc/cp/
	* constexpr.cc (cxx_fold_indirect_ref): Remove unused variables.

gcc/rust/
	* backend/rust-constexpr.cc (rs_fold_indirect_ref): Remove unused
	variables.
