From 7f5331a885c2e8b8cb8be5b27dc4bcfa290ad6c0 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Tue, 26 Mar 2019 17:30:21 -0500 Subject: [PATCH] gdb-gdb.py.in: Fix error when printing range type I noticed that trying to print the contents of a struct main_type would fail when the type was a TYPE_CODE_RANGE: (gdb) p *type.main_type $1 = Python Exception There is no member named low_undefined.: And indeed, Python is right, fields "low_undefined" has been removed from struct range_bounds back in ... 2014! It was done when we introduced dynamic bounds handling. This patch fixes gdb-gdb.py.in according to the new structure. gdb/ChangeLog: * gdb-gdb.py.in (StructMainTypePrettyPrinter.bound_img): New method. (StructMainTypePrettyPrinter.bounds_img): Use new "bound_img" method to compute the bounds of range types. Also print "[evaluated]" if the bounds' values come from a dynamic evaluation. --- gdb/ChangeLog | 7 +++++++ gdb/gdb-gdb.py.in | 28 +++++++++++++++++++++------- 2 files changed, 28 insertions(+), 7 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index a31cf70..4ef8a5c 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,10 @@ +2019-03-26 Joel Brobecker + + * gdb-gdb.py.in (StructMainTypePrettyPrinter.bound_img): New method. + (StructMainTypePrettyPrinter.bounds_img): Use new "bound_img" + method to compute the bounds of range types.
