Hi,
The below (slightly) reduced test-case from gcc.c-torture/execute/simd-2.c
produces an execution failure for avr.
typedef short __attribute__((vector_size (16))) vecint;
vecint i = { 150, 100, 150, 200, 0, 0, 0, 0 };
vecint j = { 10, 13, 20, 30, 1, 1, 1, 1 };
vecint k;
union {

Hi,
This patch series adds initial support for ISO C++'s [P1689R5][], a
format for describing C++ module requirements and provisions based on
the source code. This is required because compiling C++ with modules is
not embarrassingly parallel and need to be ordered to ensure that
`import some_modul
When passing `-o` flags to other options, the typical `-o foo` spelling
leaves a leading whitespace when replacing elsewhere. This ends up
creating flags spelled as `-some-option-with-arg= foo.ext` which doesn't
parse properly. When attempting to make a spec function to just remove
the leading whit
They affect the build, so report them via `-MF` mechanisms.

* g++.dg/modules/depreport-1_a.C: New test.

It affects the build, and if used as a static file, can reliably be
tracked using the `-MF` mechanism.

This patch implements support for [P1689R5][] to communicate to a build
system the C++20 module dependencies to build systems so that they may
build `.gcm` files in the proper order.
Support is communicated through the following three new flags:
- `-fdeps-format=` specifies the format for the out

Hi,
I recently discovered that the following C statement:
pointer++;
is semantically equivalent to the following:
*pointer++;
Is this due to operators' priority? To me, that looks weird.
Thanks in advance,
Tomas
