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/pr24716.c | 59 +++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr24716.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr24716.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr24716.c b/gcc/testsuite/gcc.c-torture/execute/pr24716.c new file mode 100644 index 000000000..c2473f84c --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr24716.c @@ -0,0 +1,59 @@ +/* PR24716, scalar evolution returning the wrong result + for pdest. */ + +int Link[] = { -1 }; +int W[] = { 2 }; + +extern void abort (void); + +int f (int k, int p) +{ + int pdest, j, D1361; + j = 0; + pdest = 0; + for (;;) { + if (pdest > 2) + do + j--, pdest++; + while (j > 2); + + if (j == 1) + break; + + while (pdest > p) + if (j == p) + pdest++; + + do + { + D1361 = W[k]; + do + if (D1361 != 0) + pdest = 1, W[k] = D1361 = 0; + while (p < 1); + } while (k > 0); + + do + { + p = 0; + k = Link[k]; + while (p < j) + if (k != -1) + pdest++, p++; + } + while (k != -1); + j = 1; + } + + /* The correct return value should be pdest (1 in the call from main). + DOM3 is mistaken and propagates a 0 here. */ + return pdest; +} + +int main () +{ + if (!f (0, 2)) + abort (); + return 0; +} + -- cgit v1.2.3
