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/gcc.dg/torture/pr51071-2.c | 38 ++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/pr51071-2.c (limited to 'gcc/testsuite/gcc.dg/torture/pr51071-2.c') diff --git a/gcc/testsuite/gcc.dg/torture/pr51071-2.c b/gcc/testsuite/gcc.dg/torture/pr51071-2.c new file mode 100644 index 000000000..f66a89f39 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/pr51071-2.c @@ -0,0 +1,38 @@ +/* { dg-do compile } */ +/* { dg-options "-fno-delete-null-pointer-checks" } */ + +extern struct module __this_module; +static inline void +trace_module_get (struct module *mod, unsigned long ip) { } +struct module; +static inline __attribute__((no_instrument_function)) +int try_module_get(struct module *module) +{ + int ret = 1; + if (module) + { + if (module_is_live(module)) + { + __label__ __here; + asm(""); + __here: + trace_module_get(module, (unsigned long)&&__here); + } + else + ret = 0; + } + return ret; +} +struct net_device; +struct net_device_ops { + int (*ndo_open)(struct net_device *dev); +}; +int t3e3_open(struct net_device *dev) +{ + int ret = hdlc_open(dev); + if (ret) + return ret; + try_module_get((&__this_module)); + return 0; +} +const struct net_device_ops t3e3_ops = { .ndo_open = t3e3_open }; -- cgit v1.2.3
