From 6571a3815623d907b7a3f560e909edd8c76a9e1c Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sun, 1 Mar 2015 20:33:00 -0700 Subject: [PATCH] Fix PR cli/18053 PR cli/18053 concerns a couple of minor bugs in the JIT debuginfo support. First, jit-reader-load should use filename completion and support tilde expansion. Second, the help for jit-reader-unload is incorrect. While working on this I also realized that jit-reader-unload should use the no-op completer, so I've included that as well. Built and regtested on x86-64 Fedora 23. A completer test for jit-reader-load is included, but not a tilde-expansion test, as I couldn't think of a reliable way to test that. 2016-07-13 Tom Tromey PR cli/18053: * jit.c (jit_reader_load_command): Use tilde_expand.
