Subject: gccrs: Make foreverstack debug string const
X-Git-Tag: basepoints/gcc-16~798
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=48d524e2ee0142199a5eed50c7aa247cef849e5c;p=thirdparty%2Fgcc.git

gccrs: Make foreverstack debug string const

Those function should not change anything within the foreverstack, it
can therefore be made const.

gcc/rust/ChangeLog:

	* resolve/rust-forever-stack.h: Make debug functions const.
	* resolve/rust-forever-stack.hxx: Likewise.
