--- Comment #4 from Alexandre Ganea <alexandre.ganea at ubisoft dot com> ---
Hi,
We get what seems like a spurious warning at the following location in LLVM:
https://github.com/llvm/llvm-project/blob/master/llvm/lib/Target/AMDGPU/R600ISelLowering.cpp#L1718
The warning is:
// warning: array subscript is above array bounds [-Warray-bounds]
// if (NewBldVec[i] == NewBldVec[j]) {
// ~~~~~~~~~~~^
This only occurs when compiling with GCC 7.1+ and 9.1/trunk (not with 8), with
-O3 -Warray-bounds
This has been creduce'd to:
class a {
int b;
unsigned c;
public:
bool operator==(a) { return b && c; }
};
class d {
public:
void e();
};
class f {
a g(d &) const;
};
a f::g(d &h) const {
a j[1];
for (unsigned i;; i++)
for (; i;)
if (j[i] == j[0])
h.e();
}
Could you please confirm the issue?
Thank you!
