small test case
<span class="quote">>clang -cc1 -fopenmp -emit-llvm -o - x.c</span >
Operand is null
call void (%struct.ident_t*, i32, void (i32*, i32*, ...)*, ...)
@__kmpc_fork_teams(%struct.ident_t* @2, i32 4, void (i32*, i32*, ...)* bitcast
(void (i32*, i32*, i64, i32*, i32*, i32*)* @.omp_outlined. to void (i32*, i32*,
...)*), <null operand!>, i32* %conv, i32* %1, i32* %conv1)
in function __omp_offloading_806_190148a_main_l9
fatal error: error in backend: Broken function found, compilation aborted!
It seem when generate Argement for data[n], the VLASizeMap is not set. So
nullptr gets pass to function call of __kmpc_fork_teams</pre>
