Bug ID: 50893
Summary: Compiler error when converting from vector of 2x32 to
2x64-bit int on POWER7
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Backend: PowerPC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Reduced test case (on Compiler Explorer: https://godbolt.org/z/z84YY6G35):
#include <stdint.h>
typedef int32_t i32x2 __attribute__((__vector_size__(8)));
typedef int64_t i64x2 __attribute__((__vector_size__(16)));
i64x2 cvt(i32x2 a) {
return __builtin_convertvector(a, i64x2);
}
Looks like it started with clang 11.0; 10 works.
