It's not the canari which is spilled in this case, but the address to the
canari. Which means an attacker could make it point to something else than
the real canari.

Hi,
For stack protector to be robust, at no point in time the guard against
which the canari is compared must be spilled to the stack. This is achieved
by having dedicated insn pattern for setting the canari and comparing it
against the guard which doesn't reflect at RTL what is happening. However
y why ARMv8-R is not listed in t-rmprofile multilib ?

Hi Alexander,
As mentioned in [1], Arm Cortex-R52 can have either single precision or
double precision + Neon. This is reflected in GCC 8 by -mcpu=cortex-r52
defaulting to the latter (double precision + Neon) and
-mcpu=cortex-r52+nofp.dp
Hi Alexander,
As mentioned in [1], Arm Cortex-R52 can have either single precision or double
precision + Neon. This is reflected in GCC 8 by -mcpu=cortex-r52 defaulting to
the latter (double precision + Neon) and -mcpu=cortex-r52+nofp.dp giving you the
former (single precision).

I'm not sure where is the proper place to fix this. Obviously setting

Hi,
TL;DR: where to tell dejagnu about the compiler to use for building testglue?

I've just found out that testglue.c is built using the compiler in PATH when
doing out of tree testing rather than using the one specified by GCC_UNDER_TEST
(or other *_UNDER_TEST). This is because
Sorry my apologies. I see that Nathan already fixed it. Must have slipped in
during a conflict resolution during one of the many rebase between testing and
commit approval.

Attention everyone,
I've just committed a patch to move MEMMODE_* macros and enum memmodel
definitions from coretypes.h to memmodel.h. As a consequence, people who include
emit-rtl.h anywhere or include tm_p.h in the middle end need to include
memmodel.h beforehand. This is because emit-rtl.h

Hi Thomas,
Hi Matthew,
Do you particularly need a switch for this? You could view this as
simply relaxing the ABI requirements of a module, a switch would only
serve to enforce the need for a compatible ABI and error if not. If

Hi there,
I'm currently working on adding a switch to check whether public
function involve float parameters or return values. Such a check would
be useful for people trying to write code that is compatible with both
