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/attribute_plugin.c | 71 ++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 gcc/testsuite/g++.dg/plugin/attribute_plugin.c (limited to 'gcc/testsuite/g++.dg/plugin/attribute_plugin.c') diff --git a/gcc/testsuite/g++.dg/plugin/attribute_plugin.c b/gcc/testsuite/g++.dg/plugin/attribute_plugin.c new file mode 100644 index 000000000..e5b056683 --- /dev/null +++ b/gcc/testsuite/g++.dg/plugin/attribute_plugin.c @@ -0,0 +1,71 @@ +/* Demonstrates how to add custom attributes */ + +#include "gcc-plugin.h" +#include +#include "config.h" +#include "system.h" +#include "coretypes.h" +#include "tree.h" +#include "tree-pass.h" +#include "intl.h" +#include "toplev.h" +#include "plugin.h" +#include "diagnostic.h" + +int plugin_is_GPL_compatible; + +/* Attribute handler callback */ + +static tree +handle_user_attribute (tree *node, tree name, tree args, + int flags, bool *no_add_attrs) +{ + return NULL_TREE; +} + +/* Attribute definition */ + +static struct attribute_spec user_attr = + { "user", 1, 1, false, false, false, handle_user_attribute }; + +/* Plugin callback called during attribute registration */ + +static void +register_attributes (void *event_data, void *data) +{ + warning (0, G_("Callback to register attributes")); + register_attribute (&user_attr); +} + +/* Callback function to invoke before the function body is genericized. */ + +void +handle_pre_generic (void *event_data, void *data) +{ + tree fndecl = (tree) event_data; + tree arg; + for (arg = DECL_ARGUMENTS(fndecl); arg; arg = DECL_CHAIN (arg)) { + tree attr; + for (attr = DECL_ATTRIBUTES (arg); attr; attr = TREE_CHAIN (attr)) { + tree attrname = TREE_PURPOSE (attr); + tree attrargs = TREE_VALUE (attr); + warning (0, G_("attribute '%s' on param '%s' of function %s"), + IDENTIFIER_POINTER (attrname), + IDENTIFIER_POINTER (DECL_NAME (arg)), + IDENTIFIER_POINTER (DECL_NAME (fndecl)) + ); + } + } +} + +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_PRE_GENERICIZE, + handle_pre_generic, NULL); + + register_callback (plugin_name, PLUGIN_ATTRIBUTES, register_attributes, NULL); + return 0; +} -- cgit v1.2.3
