Hi Sebastian,
I currently encountered an issue when testing
gcc.dg/graphite/interchange-9.c on a ARM bare-metal board which has only 4MB
memory.
Apparently, with
#define N 1111
#define M 1111
"int A[N*M]" in main is too large to fit in stack.
There are several ways to solve this issue:
1. Make this test a compile test instead of a run test.
2. Define both M and N to 111. I checked and the test is still valid, ie it
still tests what is intended.
3. Use STACK_SIZE macro to calculate M and N. But I don't know how to do
that. And I'm not sure if we got a very small M and N, the test will be
still valid.
Which way do you like most?
I would say, let's go for solution 2.
I don't like the first solution as you want to also validate
that the transform is correct. As for solution 3, I do not know
either how to do that.
I will keep in mind these limitations for the future testcases.
Thanks. I will submit a patch for solution 2.
