From e68c32d53e44ac0fe9f48637c0113da42b62644a Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Tue, 21 Feb 2017 13:32:55 -0800 Subject: compile: set debug compile: Display GCC driver filename As discussed in How to use compile & execute function in GDB https://sourceware.org/ml/gdb/2015-04/msg00026.html GDB currently searches for compilers on /usr/bin/ARCH-OS-gcc and chooses a match from there. However, it is not currently possible for the user to display which compiler was selected. Up until now, GDB's compiler interface was not up-to-date with GCC's one, which means that it wasn't possible to obtain this information. This patch implements the mechanisms necessary for that. gdb/ChangeLog 2017-08-23 Jan Kratochvil * compile/compile.c (compile_to_object): Conditionally call set_verbose. Conditionally call compile or compile_v0. include/ChangeLog 2017-08-23 Jan Kratochvil * gcc-interface.h (enum gcc_base_api_version): Add GCC_FE_VERSION_1. (struct gcc_base_vtable): Rename compile to compile_v0. Update comment for compile. New methods set_verbose and compile. --- include/gcc-interface.h | 36 ++++++++++++++++++++++++++++-------- 1 file changed, 28 insertions(+), 8 deletions(-) (limited to 'include/gcc-interface.h') diff --git a/include/gcc-interface.h b/include/gcc-interface.h index d4c4ec6..c98f078 100644 --- a/include/gcc-interface.h +++ b/include/gcc-interface.h @@ -44,7 +44,10 @@ struct gcc_base_context; enum gcc_base_api_version { - GCC_FE_VERSION_0 = 0 + GCC_FE_VERSION_0 = 0, + + /* Deprecated method compile_v0.
