Hi,
Witnessed another ICE with option -mgeneral-regs-only.
I have created a bug for that:

For the given testcase, we are doing FAIL for scalar floating move expand

is false with option -mgeneral-regs-only. B

A user reported that gcc -m32 on x86-64 does not define __ILP32__
and I found the same on i686 (with gcc -x c -dM -E /dev/null).
The code has
if (TARGET_X32)
{
cpp_define (parse_in, "_ILP32");
cpp_define (parse_in, "__ILP32__");
}
so -mx32 does define _
This has a few pattern cleanups that are made possible now that the original
H8/300 support is gone. It also moves all the peepholes into their own file.
That's a trend that will continue with follow-up patches. Doing that allows me
to disable large chunks of code during the conversion with mini
OK. So a more substantial patch this time.
The original 8 bit H8/300 part is horrifically old. They probably haven't been
made in 20 years or longer. While the tester builds multilibs for that part, we
don't test them.
Dropping support for the original H8/300 part ultimately allows for some

In fn_type_unifcation, we are passing NULL_TREE as the 'in_decl'
parameter to coerce_template_parms, and this is causing template

AVX512-style masks and SVE-style predicates can be difficult
to debug in gimple dumps, since the types are printed like this:
vector(4) foo;
Some important details are hidden by that ,
such as the number of bits in an element and whether the type
is signed or unsigned.

The main purpose of this patch is to fix OpenMP, but it modifies
the general Fortran handling of assumed-shape optional arguments.
For assumed shape, gfortran generates an "arg.0 = arg->data"
artificial variable – and with optional one has something like
if (arg != NULL && arg->data != NULL)

This makes the declaration of arm_add_stmt_cost match the definition, and

Hi!
The following patch canonicalizes M = X >> (prec - 1); (X + M) ^ M
for signed integral types into ABS_EXPR (X). For X == min it is already
UB because M is -1 and min + -1 is UB, so we can use ABS_EXPR rather than
say ABSU_EXPR + cast.
The backend might then emit the abs code back using the s
Hi!
The ffs expanders on several targets (x86, ia64, aarch64 at least)

argument is 0, which makes the code longer.
If we know from VRP that the argument will not be zero, we can (if the
target has also an ctz expander) just use ct

Let's discourage people from parsing of the coverage files.
We invented `gcov --json-format` for those who need a machine

std::copy/std::copy_n overloads for char* will also be used for
std::deque iterators when dealing with istreambuf_iterator. It
also make sure that it still works when _GLIBCXX_DEBUG is activated.
