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/20020706-1.c | 50 ++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/20020706-1.c (limited to 'gcc/testsuite/gcc.c-torture/compile/20020706-1.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/20020706-1.c b/gcc/testsuite/gcc.c-torture/compile/20020706-1.c new file mode 100644 index 000000000..c8811bc68 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/20020706-1.c @@ -0,0 +1,50 @@ +// Contributed by Alexandre Oliva +// From Red Hat case 106165. + +typedef struct s1 +{ + unsigned short v1; + unsigned char *v2; +} S1; + +extern void bar(const struct s1 *const hdb); +extern unsigned char* foo (); + +unsigned int sn; +S1 *hdb; +S1 *pb; +unsigned short len; + +unsigned int crashIt() +{ + unsigned char *p; + unsigned int nsn; + unsigned short cnt; + + if (sn != 0) return 1; + + if ((len < 12) || ((p = (((pb->v1) >= 8) ? pb->v2 : foo() )) == 0)) + return 1; + + nsn = ( + (((*(unsigned int*)p) & 0x000000ff) << 24) | + (((*(unsigned int*)p) & 0x0000ff00) << 8) | + (((*(unsigned int*)p) & 0x00ff0000) >> 8) | + (((*(unsigned int*)p) & 0xff000000) >> 24) ); + p += 4; + + cnt = (unsigned short) (( + (((*(unsigned int*)p) & 0x000000ff) << 24) | + (((*(unsigned int*)p) & 0x0000ff00) << 8) | + (((*(unsigned int*)p) & 0x00ff0000) >> 8) | + (((*(unsigned int*)p) & 0xff000000) >> 24) ) & + 0xffff); + + if ((len != 12 + (cnt * 56)) || (nsn == 0)) + { + bar(hdb); + return 1; + } + + return 0; +} -- cgit v1.2.3
