From 9c6595ab6873e15fe533b05bb7b98c11f17c5d57 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 29 Oct 2015 12:55:01 +0000 Subject: Don't assume break/continue inside a TRY block works In C++, this: try { break; } catch (..) {} is invalid. However, because our TRY/CATCH macros support it in C, the C++ version of those macros support it too. To catch such assumptions, this adds a (disabled) hack that maps TRY/CATCH to raw C++ try/catch. Then it goes through all instances that building on x86_64 GNU/Linux trips on, fixing them. This isn't strictly necessary yet, but I think it's nicer to try to keep the tree in a state where it's easier to eliminate the TRY/CATCH macros. gdb/ChangeLog: 2015-10-29 Pedro Alves * dwarf2-frame-tailcall.c (dwarf2_tailcall_sniffer_first): Don't assume that "break" breaks out of a TRY/CATCH. * python/py-framefilter.c (py_print_single_arg): Don't assume "continue" breaks out of a TRY/CATCH. * python/py-value.c (valpy_binop_throw): New function, factored out from ...
