Bug ID: 98315
Summary: [11 regression] libcody breaks Solaris bootstrap
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: nathan at gcc dot gnu.org
Target Milestone: ---
Target: *-*-solaris2.11
Since the introduction of libcody, Solaris 11 bootstrap is broken:
* On Solaris 11.4:
In file included from /usr/include/sys/socket.h:25,
from /vol/gcc/src/hg/master/local/gcc/../libcody/cody.hh:29,
from /vol/gcc/src/hg/master/local/gcc/cp/mapper-client.h:26,
from /vol/gcc/src/hg/master/local/gcc/cp/mapper-client.cc:26:
/usr/include/sys/uio.h:192:3: error: attempt to use poisoned "bzero"
bzero(&(xuiop)->xu_hint, sizeof ((xuiop)->xu_hint)); \
^
where <sys/uio.h> has
/*
* Clear the hints portion of an xuio_t, leaving the initial uio_t and the
* xu_ext union untouched.
*
* Note that this does not touch xu_type. Since zero copy is recognized as
* UIO_XUIO with xu_type of UIOTYPE_ZEROCOPY, if extending a uio_t not setup
* for zero copy into a full xuio_t then chances are that xu_type should be
* initialized too as if the xuio_t had been bzero'd - ie to UIOTYPE_ASYNCIO.
*/
#define XUIO_BZERO_HINTS(xuiop) do { \
bzero(&(xuiop)->xu_hint, sizeof ((xuiop)->xu_hint)); \
_NOTE(CONSTCOND) } while (0)
This macros isn't used anywhere, so I wonder why #pragma poison would be
offended.
* On Solaris 11.3:
In file included from /usr/include/sys/stream.h:16,
from /usr/include/netinet/in.h:66,
from /usr/include/sys/socket.h:32,
from /vol/gcc/src/hg/master/local/gcc/../libcody/cody.hh:29,
from /vol/gcc/src/hg/master/local/gcc/cp/mapper-client.h:26,
from /vol/gcc/src/hg/master/local/gcc/cp/mapper-client.cc:26:
/usr/include/sys/strmdep.h:25:26: error: attempt to use poisoned "bcopy"
#define strbcpy(s, d, c) bcopy(s, d, c)
^
with the following in <sys/strmdep.h>:
/*
* Copy data from one data buffer to another.
* The addresses must be word aligned - if not, use bcopy!
*/
#define strbcpy(s, d, c) bcopy(s, d, c)
I've hacked around both for no by removing bcopy and bzero from #pragma GCC
poison
in gcc/system.h.
