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/pr41248.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr41248.c (limited to 'gcc/testsuite/gcc.dg/pr41248.c') diff --git a/gcc/testsuite/gcc.dg/pr41248.c b/gcc/testsuite/gcc.dg/pr41248.c new file mode 100644 index 000000000..0d5a74919 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr41248.c @@ -0,0 +1,27 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -g" } */ + +struct __gcov_var { + unsigned int offset; + unsigned int buffer[(1 << 10) + 1]; +} __gcov_var; +unsigned int * gcov_write_words (unsigned int words) { + unsigned int *result; + result = &__gcov_var.buffer[__gcov_var.offset]; + return result; +} + +struct gcov_ctr_summary { }; +struct gcov_summary { + unsigned int checksum; + struct gcov_ctr_summary ctrs[1]; +}; +void __gcov_write_unsigned (unsigned int); +void __gcov_write_summary (unsigned int tag, + const struct gcov_summary *summary) +{ + unsigned ix; + const struct gcov_ctr_summary *csum; + __gcov_write_unsigned (summary->checksum); + for (csum = summary->ctrs, ix = 1; ix--; csum++) { } +} -- cgit v1.2.3
