From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/g++.dg/plugin/pragma_plugin.c | 62 +++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 gcc/testsuite/g++.dg/plugin/pragma_plugin.c (limited to 'gcc/testsuite/g++.dg/plugin/pragma_plugin.c') diff --git a/gcc/testsuite/g++.dg/plugin/pragma_plugin.c b/gcc/testsuite/g++.dg/plugin/pragma_plugin.c new file mode 100644 index 000000000..940c302df --- /dev/null +++ b/gcc/testsuite/g++.dg/plugin/pragma_plugin.c @@ -0,0 +1,62 @@ +/* Demonstrates how to add custom pragmas */ + +#include "gcc-plugin.h" +#include +#include "config.h" +#include "system.h" +#include "coretypes.h" +#include "tm.h" +#include "rtl.h" +#include "tree.h" +#include "function.h" +#include "c-family/c-pragma.h" +#include "cpplib.h" +#include "tree-pass.h" +#include "intl.h" +#include "toplev.h" +#include "diagnostic.h" + +int plugin_is_GPL_compatible; + + +/* handler of #pragma GCCPLUGIN sayhello "message" is quite similar to + handler of #pragma GCC message...*/ + +static void +handle_pragma_sayhello (cpp_reader *dummy) +{ + tree message = 0; + if (pragma_lex (&message) != CPP_STRING) + { + warning (OPT_Wpragmas, "%<#pragma GCCPLUGIN sayhello%> is not a string"); + return; + } + if (TREE_STRING_LENGTH (message) > 1) + if (cfun) + warning (OPT_Wpragmas, + "% from function %qE: %s", + cfun->decl, TREE_STRING_POINTER (message)); + else + warning (OPT_Wpragmas, + "% outside of function: %s", + TREE_STRING_POINTER (message)); +} + +/* Plugin callback called during pragma registration */ + +static void +register_my_pragma (void *event_data, void *data) +{ + warning (0, G_("Callback to register pragmas")); + c_register_pragma ("GCCPLUGIN", "sayhello", handle_pragma_sayhello); +} + +int +plugin_init (struct plugin_name_args *plugin_info, + struct plugin_gcc_version *version) +{ + const char *plugin_name = plugin_info->base_name; + + register_callback (plugin_name, PLUGIN_PRAGMAS, register_my_pragma, NULL); + return 0; +} -- cgit v1.2.3
