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/loop-2e.c | 39 +++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/loop-2e.c (limited to 'gcc/testsuite/gcc.c-torture/execute/loop-2e.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/loop-2e.c b/gcc/testsuite/gcc.c-torture/execute/loop-2e.c new file mode 100644 index 000000000..71c7a4d1d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/loop-2e.c @@ -0,0 +1,39 @@ +void f (int *p, int **q) +{ + int i; + for (i = 0; i < 40; i++) + { + *q++ = &p[i]; + } +} + +int main () +{ + void *p; + int *q[40]; + __SIZE_TYPE__ start; + + /* Find the signed middle of the address space. */ + if (sizeof(start) == sizeof(int)) + start = (__SIZE_TYPE__) __INT_MAX__; + else if (sizeof(start) == sizeof(long)) + start = (__SIZE_TYPE__) __LONG_MAX__; + else if (sizeof(start) == sizeof(long long)) + start = (__SIZE_TYPE__) __LONG_LONG_MAX__; + else + return 0; + + /* Arbitrarily align the pointer. */ + start &= -32; + + /* Pretend that's good enough to start address arithmetic. */ + p = (void *)start; + + /* Verify that GIV replacement computes the correct results. */ + q[39] = 0; + f (p, q); + if (q[39] != (int *)p + 39) + abort (); + + return 0; +} -- cgit v1.2.3
