From 1c8e84b0827ace271c460abcc13df9414304cc09 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Tue, 1 Oct 2013 09:21:41 +0000 Subject: [PATCH] wrong "catch exception" error message when finding trampoline msym. When building the program with the shared GNAT runtime, the debugger is unable to insert Ada exception catchpoints until that runtime has been mapped to memory. In other words, we expect the user to start the program first, before attempting to insert that catchpoint. The detection mechanism that tries to provide some useful tips to the user fails when the program itself contains a trampoline symbol matching the symbol that the catchpoint is trying to use. This results in the following error message: (gdb) catch exception Your Ada runtime appears to be missing some debugging information. Cannot insert Ada exception catchpoint in this configuration. Instead, we expected the following error message: (gdb) catch exception Unable to insert catchpoint. Try to start the program first. gdb/ChangeLog: * ada-lang.c (ada_has_this_exception_support): Ignore mst_solib_trampoline minimal symbols. --- gdb/ChangeLog | 5 +++++ gdb/ada-lang.c | 5 ++++- 2 files changed, 9 insertions(+), 1 deletion(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index bcf0169..15ca4f2 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,8 @@ +2013-10-01 Joel Brobecker + + * ada-lang.c (ada_has_this_exception_support): Ignore + mst_solib_trampoline minimal symbols. + 2013-09-30 Tristan Gingold * i386-darwin-nat.c (darwin_complete_target): Install methods for diff --git a/gdb/ada-lang.c b/gdb/ada-lang.c index d2b0ed2..62ca50c 100644 --- a/gdb/ada-lang.c +++ b/gdb/ada-lang.c @@ -11039,7 +11039,10 @@ ada_has_this_exception_support (const struct exception_support_info *einfo) the name of the exception being raised (this name is printed in the catchpoint message, and is also used when trying to catch a specific exception).
