From: Tom Tromey Date: Mon, 8 Mar 2021 14:27:57 +0000 (-0700) Subject: Implement dumping X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=de401988aeac56a8478f61cde1b35e961742317b;p=binutils-gdb.git Implement dumping This patch implements the dumping methods for tuple_holding_operation. A number of overloads are used. Note that no default case is given. This approach makes it simple to detect when a new overload is needed -- compilation will fail. (There is an example of this in a later patch in the series.) gdb/ChangeLog 2021-03-08 Tom Tromey * expprint.c (expr::dump_for_expression): New functions. * expop.h (dump_for_expression): New overloads.
