From: Ulrich Drepper Date: Thu, 11 Dec 2014 04:31:52 +0000 (+0000) Subject: Minor interface cleanups of libgccjit X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c168eab92cc42d3c995cc0a1188e1554ebbcd63a;p=gcc.git Minor interface cleanups of libgccjit Minor interface cleanups of libgccjit * jit/jit-playback.c (convert_to_dso): Use auto_vec instead of automatic array to build up command line. * jit/jit-recording.c (recording::context::set_str_option): Make copy of the string. (recording::context::~context): Free string options. * jit/jit-recording.h (recording::context): Adjust type of m_str_options member. * jit/libgccjit.h: Adjust comment about gcc_jit_context_set_str_option parameter begin used after the call. Update comment now that all interfaces are copy strings if necessary. * jit/libgccjit++.h (gccjit::context): Add set_str_option member function.
