Bug ID: 50699
Summary: [OpenMP] "DeclRefExpr for Decl not entered in
LocalDeclMap?"
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: OpenMP
Assignee: unassignedclangbugs at nondot.org
Reporter: lebedev.ri at gmail.com
CC: llvm-bugs at lists.llvm.org
Reduced from darktable's gradient.c
I'm not sure when this problem was introduced,
i think it was hidden by the `complex` handling bug.
$ cat input.c
a;
b() {
float *c;
#pragma omp parallel for simd aligned(c)
for (int d = 3; d < a; d++)
;
}
$ /builddirs/llvm-project/build-Clang12/bin/clang input.c -fopenmp
input.c:1:1: warning: type specifier missing, defaults to 'int'
[-Wimplicit-int]
a;
^
input.c:2:1: warning: type specifier missing, defaults to 'int'

b() {
