Bug ID: 88316
Summary: numerous big-endian issues with compatibility
implementations of vector intrinsics for powerpc
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: pc at gcc dot gnu.org
Target Milestone: ---
Many of the test cases for the compatibility implementations of x86 vector
intrinsics for powerpc were structured like:
--
int
main ()
{
#ifdef __BUILTIN_CPU_SUPPORTS__
/* testing code */
#endif /* __BUILTIN_CPU_SUPPORTS__ */
return 0;
}
--
...which had the unfortunate side-effect of allowing all such tests to silently
pass without actually testing anything. Removing the protective #ifdef permits
the tests to run, which has the unfortunate side-effect of exposing a raft of
big-endian (and 32bit mode) bugs.
I will tackle these en-masse.
