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.c-torture/compile/pr31797.c | 31 +++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/pr31797.c (limited to 'gcc/testsuite/gcc.c-torture/compile/pr31797.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/pr31797.c b/gcc/testsuite/gcc.c-torture/compile/pr31797.c new file mode 100644 index 000000000..97958f389 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/pr31797.c @@ -0,0 +1,31 @@ +struct GTeth_desc +{ + unsigned ed_cmdsts; +}; +struct GTeth_softc +{ + struct GTeth_desc txq_desc[32]; + unsigned int txq_fi; + unsigned int txq_nactive; +}; + +void +GTeth_txq_free (struct GTeth_softc *sc) +{ + struct GTeth_desc *txd = &sc->txq_desc[0]; + txd->ed_cmdsts &= ~(1U << (31)); +} +void +GTeth_txq_done (struct GTeth_softc *sc) +{ + while (sc->txq_nactive > 0) + { + volatile struct GTeth_desc *txd = &sc->txq_desc[sc->txq_fi]; + if (txd->ed_cmdsts) + { + if (sc->txq_nactive == 1) + return; + } + GTeth_txq_free (sc); + } +} -- cgit v1.2.3
