From d2242e347a25dc15fbf7286975e3baba143deea9 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 29 Oct 2015 16:18:30 +0000 Subject: [PATCH] mdebugread.c: Address class -> address class index MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This fixes this error in C++ mode: /home/pedro/gdb/mygit/cxx-convertion/src/gdb/mdebugread.c:654:11: error: invalid conversion from ‘int’ to ‘address_class’ [-fpermissive] theclass = mdebug_register_index; ^ The "theclass" local is of type enum address_class, however, what it really holds is an address class index. Class index values by design match the address class values up until LOC_FINAL_VALUE, but extend beyond that, so it's not really right to store an address class index in an enum address_class. The fix is really the same making the 'theclass' local be of type int, but while we're at it, we get rid of the goto, and thus the local becomes the 'aclass_index' parameter in the new add_data_symbol function. gdb/ChangeLog: 2015-10-29 Pedro Alves * mdebugread.c (add_data_symbol): New function, factored out from ...
