Subject: debug/94273 - avoid creating type DIEs for DINFO_LEVEL_TERSE
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=45cfaf9903d3f5aa916d330f2013eb7d820a7137;p=gcc.git

debug/94273 - avoid creating type DIEs for DINFO_LEVEL_TERSE

This avoids completing types for DINFO_LEVEL_TERSE by using
the should_emit_struct_debug machinery.

2020-03-27  Richard Biener  <rguenther@suse.de>

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

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