Fail to resolve array size

[drhaozhong]

The code is as follows:

int n = 0, p[n * 0 + 1];

The error message is:

error: variable length array declaration not allowed at file scope
int n = 0, p[n * 0 + 1];
^ ~~~~~~~~~
1 error generated.

The size of p can be calculated, since n is zero.
GCC accepts the above code.

@drhaozhong, thanks for the report. It turned out it is not a DPC++-specific error because it is reproduced on mainline LLVM, the reproducer is: https://godbolt.org/z/dYhq8En39.

@drhaozhong other issues are also not DPC++-related. We address here only DPC++-specific issues because we develop DPC++ compiler in this fork.
To get the quick feedback on your reports, can you please submit them to the mainline LLVM bug tracker? (https://github.com/llvm/llvm-project/issues)

@drhaozhong may hope that DPC++ could solve these issues when the mainline LLVM won't.
