Richard Biener March 27, 2020, 12:59 p.m.
This avoids completing types for DINFO_LEVEL_TERSE by using
the should_emit_struct_debug machinery.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

	PR debug/94273
	* dwarf2out.c (should_emit_struct_debug): Return false for
	DINFO_LEVEL_TERSE.

	* g++.dg/debug/pr94273.C: New testcase.
