Bug ID: 45439
Summary: OpenMP `omp for collapse(2) ordered(2)` generates
invalid IR
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: OpenMP
Assignee: unassignedclangbugs at nondot.org

OS: Linux
CPU: x86_64 and AArch64
LLVM/Clang/OpenMP: latest master branch (commit 74d44c43e8c)
When I compile `doacross.4.c` in the official 'OpenMP Examples Version 5.0.0'
<https://github.com/OpenMP/Examples/blob/v5.0.0/sources/Example_doacross.4.c>
into the LLVM IR and compile the generated IR, the IR verifier detects an
error.
----------------------------------------------------------------
$ clang -fopenmp -S -emit-llvm Example_doacross.4.c
$ clang -fopenmp Example_doacross.4.ll
Example_doacross.4.ll:91:9: error: stored value and pointer type do not match
store i32 %64, i64* %59, align 8
^
1 error generated.
----------------------------------------------------------------
I created a small reproducer.
----------------------------------------------------------------
void work(int N, int M)
{
#pragma omp for collapse(2) ordered(2)
for (int i = 0; i < N; i++)
for (int j = 0; j < M; j++)
;
}
----------------------------------------------------------------
When I compile the reproducer with the Clang/LLVM release build, the same error
occurs:
----------------------------------------------------------------
$ clang -fopenmp -S -emit-llvm reproducer.c
$ clang -fopenmp reproducer.ll
reproducer.ll:76:9: error: stored value and pointer type do not match

When I compile the reproducer with the Clang/LLVM debug build, an assersion
failure occurs:
----------------------------------------------------------------

PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
