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/execute/memset-1.c | 96 ++++++++++++++++++++++++++ 1 file changed, 96 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/memset-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/memset-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/memset-1.c b/gcc/testsuite/gcc.c-torture/execute/memset-1.c new file mode 100644 index 000000000..b0b70f3e6 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/memset-1.c @@ -0,0 +1,96 @@ +/* Copyright (C) 2002 Free Software Foundation. + + Test memset with various combinations of pointer alignments and lengths to + make sure any optimizations in the library are correct. + + Written by Michael Meissner, March 9, 2002. */ + +#include + +#ifndef MAX_OFFSET +#define MAX_OFFSET (sizeof (long long)) +#endif + +#ifndef MAX_COPY +#define MAX_COPY (10 * sizeof (long long)) +#endif + +#ifndef MAX_EXTRA +#define MAX_EXTRA (sizeof (long long)) +#endif + +#define MAX_LENGTH (MAX_OFFSET + MAX_COPY + MAX_EXTRA) + +static union { + char buf[MAX_LENGTH]; + long long align_int; + long double align_fp; +} u; + +char A = 'A'; + +main () +{ + int off, len, i; + char *p, *q; + + for (off = 0; off < MAX_OFFSET; off++) + for (len = 1; len < MAX_COPY; len++) + { + for (i = 0; i < MAX_LENGTH; i++) + u.buf[i] = 'a'; + + p = memset (u.buf + off, '\0', len); + if (p != u.buf + off) + abort (); + + q = u.buf; + for (i = 0; i < off; i++, q++) + if (*q != 'a') + abort (); + + for (i = 0; i < len; i++, q++) + if (*q != '\0') + abort (); + + for (i = 0; i < MAX_EXTRA; i++, q++) + if (*q != 'a') + abort (); + + p = memset (u.buf + off, A, len); + if (p != u.buf + off) + abort (); + + q = u.buf; + for (i = 0; i < off; i++, q++) + if (*q != 'a') + abort (); + + for (i = 0; i < len; i++, q++) + if (*q != 'A') + abort (); + + for (i = 0; i < MAX_EXTRA; i++, q++) + if (*q != 'a') + abort (); + + p = memset (u.buf + off, 'B', len); + if (p != u.buf + off) + abort (); + + q = u.buf; + for (i = 0; i < off; i++, q++) + if (*q != 'a') + abort (); + + for (i = 0; i < len; i++, q++) + if (*q != 'B') + abort (); + + for (i = 0; i < MAX_EXTRA; i++, q++) + if (*q != 'a') + abort (); + } + + exit (0); +} -- cgit v1.2.3
