Subject: Emit correct debug info for 64-bit signed enums on 64-bit host.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=25dd13ece0ff96888ad87c1832b7cccda32ade1e;p=gcc.git

Emit correct debug info for 64-bit signed enums on 64-bit host.

	* dwarf2out.c (size_of_die, case dw_val_class_const): Use
	size_of_sleb128.
	(value_format, case dw_val_class_const): Use sdata format.
	(output_die): Call output_sleb128.
