From 6b95f5ad9684530960eb828c76755a7b27a44e43 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Wed, 5 May 2021 15:26:28 +0100 Subject: gdb/python: allow for catchpoint type breakpoints in python This commit adds initial support for catchpoints to the python breakpoint API. This commit adds a BP_CATCHPOINT constant which corresponds to GDB's internal bp_catchpoint. The new constant is documented in the manual. The user can't create breakpoints with type BP_CATCHPOINT after this commit, but breakpoints that already exist, obtained with the `gdb.breakpoints` function, can now have this type. Additionally, when a stop event is reported for hitting a catchpoint, GDB will now report a BreakpointEvent with the attached breakpoint being of type BP_CATCHPOINT - previously GDB would report a generic StopEvent in this situation. gdb/ChangeLog: * NEWS: Mention Python BP_CATCHPOINT feature. * python/py-breakpoint.c (pybp_codes): Add bp_catchpoint support. (bppy_init): Likewise. (gdbpy_breakpoint_created): Likewise. gdb/doc/ChangeLog: * python.texinfo (Breakpoints In Python): Add BP_CATCHPOINT description. gdb/testsuite/ChangeLog: * gdb.python/py-breakpoint.c (do_throw): New function. (main): Call do_throw. * gdb.python/py-breakpoint.exp (test_catchpoints): New proc. --- gdb/testsuite/gdb.python/py-breakpoint.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'gdb/testsuite/gdb.python/py-breakpoint.c') diff --git a/gdb/testsuite/gdb.python/py-breakpoint.c b/gdb/testsuite/gdb.python/py-breakpoint.c index 830e4c2..dca668d 100644 --- a/gdb/testsuite/gdb.python/py-breakpoint.c +++ b/gdb/testsuite/gdb.python/py-breakpoint.c @@ -39,6 +39,11 @@ int add (int i) return i + i; /* Break at function add. */ } +void +do_throw () +{ + throw 123; +} int main (int argc, char *argv[]) { @@ -46,6 +51,15 @@ int main (int argc, char *argv[]) int bar = 42; int i; + try + { + do_throw (); + } + catch (...) + { + /* Nothing. */ + } + for (i = 0; i < 10; i++) { result += multiply (foo); /* Break at multiply. */ -- cgit v1.1
