Long doubles are tricky when it comes to considering singletons
because small numbers and +-INF can have multiple representations for
the same number. So we need to be very careful not to treat those as
singletons, lest they be incorrectly propagated by VRP. This is
similar to the -0.0 and +0.0 d

Jakub has mentioned that for -funsafe-math-optimizations we may flush
denormals to zero, in which case we need to be careful to extend the
ranges to the appropriate zero. This patch does exactly that. For a
range of [x, -DENORMAL] we flush to [x, -0.0] and for [+DENORMAL, x]
we flush to [+0.0, x]

The old stack detection was performed before the stack was dropped,

The current stack detection scheme is as follows:

Checking that the triplet matches arm*-*-eabi (or msp430-*-*) is not
enough to know if the execution will enter an endless loop, or if it
will give a meaningful result. As the execution test only work when
VMA and LMA are equal, make sure that this condition is met.

Hi,
These operations were added to Fortran 2018, and correspond to well-defined
IEEE comparison operations, with defined signaling semantics for NaNs. All are
implemented in terms of GCC expressions and built-ins, with no library support
needed.

Hi,
The IEEE_MODES_TYPE type and the two functions that get and set it were added
in Fortran 2018. They can be implemented using the already existing
target-specific functions. A future optimization could, on some targets,
set/get all modes th

Hi Mikael,
This adds support for clobbering of partial variable references, when
they are passed as actual argument and the associated dummy has the
INTENT(OUT) attribute.
Support includes array elements, derived type component references,
and complex real or imaginary parts.
This is done by

The testcase from the patch was not specifically checking lack of
