Hi.
Following the recent introduction of more detailed CLOBBER types in GCC,
a minor
inconsistency has been identified in the description of
CLOBBER_OBJECT_BEGIN:
/* Beginning of object lifetime, e.g. C++ constructor. */
CLOBBER_OBJECT_BEGIN
This comment appears somewhat contradictory,

I'm however able to reproduce it at -Ofast alone, no need for `-flto`
My earlier patch appears to have caused some regressions. I've taken a
quick look to see if there are obvious workarounds, but given the time
frame and the fact that I still don't really understand all the details
of how and when symbols get emitted, I felt it was safer to revert the
non-modules

Being very
In this PR, the SME mode-switching code needs to insert a stack-probe
loop for an alloca. This patch allows the target to do that.
There are two parts to it: allowing loops for insertions in blocks,
and allowing them for insertions on edges. The former can be handled
entirely within

this down, BTW.

does have one (courtesy of int_range<>), so things get

Hi!
The following testcase ICEs, because can_test_argument_range
returns true for BUILT_IN_{COSH,SINH,EXP{,M1,2}}{F32X,F64X}

those.

The minimal runtime has been documented from the beginning to break some
standard features in order to reduce code size, while keeping
the features required by typical firmware programs. Document one more
