From 5c9878f19c644e782250d19f895b68d681055d86 Mon Sep 17 00:00:00 2001 From: John Gilmore Date: Mon, 19 Aug 1991 20:55:06 +0000 Subject: [PATCH] * breakpoint.c (bpstat_do_actions): Use a cleanup to restore executing_breakpoint_commands if we are interrupted by error. * coffread.c (init_lineno): Avoid problem with zero-sized linetab versus malloc/free. From: john@labtam.labtam.oz.au (John Carey). * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a catch_errors() so we can setup the frame regardless of whether the shared libs work. * ieee-float.c (double_to_ieee_extended): Get exponent from right place in little-endian systems.
