Bug ID: 26828
Summary: -frewrite-includes: incorrect support of
__has_include_next
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: eugvelesev...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Created attachment 15980
--> https://llvm.org/bugs/attachment.cgi?id=15980&action=edit
The test mentioned in the bug description.
Now __has_include_next is handled as __has_include:
include_next.cpp:
#include <h.h>
inc/h.h:
#if __has_include_next(<h.h>) /* expands in 1 */
#include_next <h.h>
#else
int main() { int inc; }
#endif
inc2/h.h:
#if __has_include_next(<h.h>) /* incorrectly expands in 1 */
#include_next <h.h>
#else
int main() { int inc2; }
#endif
"clang++ -frewrite-includes -E include_next.cpp -isystem inc -isystem inc2 |
clang++ -E -" produces empty file(with line directives).
