X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=88272c019414e6558db9c6c72053415fa88e0b5e;p=gcc.git

dwarf2out.c (tree_add_const_value_attribute): For INTEGER_CST that fits into uhwi or shwi...

	* dwarf2out.c (tree_add_const_value_attribute): For INTEGER_CST
	that fits into uhwi or shwi, add DW_AT_const_value regardless
	of early_dwarf without going through RTL, using add_AT_unsigned
	or add_AT_int.

	* g++.dg/debug/dwarf2/template-params-13.C: New test.
	* g++.dg/debug/dwarf2/template-params-5.C: Adjust regexps so that
	it doesn't match newlines.
