Product: gcc
Component: gcc
Summary: [alpha] unrecognizable insn compiling fork.c of kernel
(and glibc)
Product: gcc
Version: 3.3.1-2mdk
Platform: DEC
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gcc
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
I'm seeing this behaviour on the alpha with recent version of gcc. This bug
is preventing glibc and kernel packages from building.
This bug has also been logged in gnu's gcc bugzilla, bug #11717:
