Bug ID: 118106
Summary: Erroneous warning: variably modified '<variable>' at
file scope
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: beni.falk at gmail dot com
Target Milestone: ---
Created attachment 59908

Result of running the compiler with -v option
The following code:
static int state[(unsigned) (4. / 2)];
int main (int argc, char **argv)
{
argc = argc; argv = argv;
state[0] = 1;
return 0;
}
triggers the above warning.
If I change the declaration to:
static int state[(unsigned) 4.];
Then the problem does not occur.
Additional information:
a) The compiler is part of Vitis 2023.2 (from AMD - formerly Xilinx)
b) The software runs on a PC under Windows 10 (Version 22H2, OS Build
19045.5247)
c) Compilation target is ARM (64-bit).
