Bug ID: 45365
Summary: ppc64le: including <stdbool.h> prior to <altivec.h>
causes compilation to fail in C mode
Product: clang
Version: 10.0
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: cl...@evan.coeusgroup.com
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org,

This is trivial to reproduce:
#include <stdbool.h>
#include <altivec.h>
And compile with clang (not clang++). The result is lots of "error: unknown
type name 'vector'".
AFAICT the problem is that stdbool.h defines bool to _Bool, then gets confused
when using types like "vector bool char" (which is "vector _Bool char" after
preprocessing).
I'm not really sure why, but it works in GCC. Maybe they just treat _Bool the
same as bool for AltiVec. It would be really nice if clang worked, too.
