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/g++.dg/ext/vla9.C | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/g++.dg/ext/vla9.C (limited to 'gcc/testsuite/g++.dg/ext/vla9.C') diff --git a/gcc/testsuite/g++.dg/ext/vla9.C b/gcc/testsuite/g++.dg/ext/vla9.C new file mode 100644 index 000000000..c58edbc9b --- /dev/null +++ b/gcc/testsuite/g++.dg/ext/vla9.C @@ -0,0 +1,38 @@ +// PR c++/43555 +// { dg-options "" } +// { dg-do run } + +extern "C" void * malloc (__SIZE_TYPE__); +extern "C" int printf (const char *, ...); +extern "C" void abort(void); + +int nx,ny; + +void f(double *x1d,int choice) +{ + double (*x2d)[nx][ny]=(double(*)[nx][ny])x1d; + unsigned long delta; +// (*x2d)[0][0]=123; // <- this line affects the result + if (choice!=0) + { + delta=&(*x2d)[1][0]-x1d; + } + else + { + delta=&(*x2d)[1][0]-x1d; + } + printf("Choice: %d, Delta: %ld\n",choice,delta); + if (delta != ny) + abort (); +} + +int main() +{ + double *data; + nx=100; + ny=100; + data=(double*)malloc(nx*ny*sizeof(double)); + f(data,0); + f(data,1); + return 0; +} -- cgit v1.2.3
