Bug ID: 121464
Summary: MCRR{2} and MRRC{2} wrongfully reject CP>7
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: avieira at gcc dot gnu.org
Target Milestone: ---
The arm ACLE intrinsics __arm_{mcrr,mcrr2,mrcc,mrcc2} should accept coproc
parameters in the range of 0-15, but GCC errors when any value larger than 7 is
used.
This is due to a copy-paste error from the single-register variants that only
support access to coproc's 0-7.
This is broken since implementation in GCC 7
