[In GCC 12 the new parameter `min-pagesize` is added and defaults 4 kB.][1]
It treats INTEGER_CST addresses smaller than that as assumed results of
pointer arithmetics from NULL while addresses equal or larger than that
as expected user constant addresses. For GCC 13 we can represent results
from pointer arithmetics on NULL using &MEM[(void*)0 + offset] instead
of (void*)offset INTEGER_CSTs.

When payloads analyze the coverage using gcov (or lcov), the gcov
version must match the CC version. Otherwise gcov would fail to parse
the .gcno files.
Therefore, define GCOV_${TARCH} in xcompile, so that payloads don't need
to do tedious string manipulations to find the right gcov path.

When looking for C compilers, xcompile uses the "" prefix to "gcc" and
"clang" as a last-resort option. This fails in environments where such
default names are blocked to prevent "unclean" builds - such as Chrome
OS.
Allow overriding this prefix using the GENERIC_COMPILER_PREFIX variable
that is hopefully both descriptive enough to suggest what it is for and
unusual enough to not trigger by chance.

According to the C standard, accessing the NULL pointer (memory at
address zero) is undefined behaviour, and so GCC is allowed to optimize
it out. Of course, accessing this memory location is sometimes
necessary, so this optimization can be disabled using
-fno-delete-null-pointer-checks. This is already done in coreboot, but
adding it to xcompile will also disable it for all the payloads. For
example, coreinfo compiled with LTO libpayload crashes when this flag
isn't set, presumably because the compiler is optimizing something out
that it shouldn't.

use either its own runtime library (compiler-rt), or gcc's version
(libgcc). Also unlike gcc, the version of clang that is currently part
of our reference toolchain does not provide the necessary versions of
compiler-rt for all platforms we support. Hence, for now, use libgcc
even on clang builds. This patch allows switching between the two, but
switching to compiler-rt will break clang builds, unless someone fixes
our reference toolchain to provide libclang_rt.builtins-${ARCH}.a for
each of our supported platforms.

The former only exists with a custom patch while the latter is supported
by clang and in the absense of libgcc even points to clang's own runtime
libraries.

Speed up the execution of this script from ~6 seconds to ~1 on my
system.
There are some changes to its output, but they're actually _more_
correct: so far, architectures without compiler support kept compiler
options for architectures that ran successfully earlier.

This change adds armv7-r support for all stages.
armv7-r is an ARM processor based on the Cortex-R series.
Currently, there is support for armv7-a and armv7-m and
armv7-a files has been modfied to accommodate armv7-r by
adding ENV_ARMV7_A, ENV_ARMV7_R and ENV_ARMV7_M constants
to src/include/rules.h.
armv7-r exceptions support will added in a later time.

Just because an 'as' with a certain prefix is available does not guarantee
that a 'gcc' with the same prefix is available as well.
Without a check detect_compiler_runtime() would try to execute an
unavailable binary and print something like this:

There was a report that xcompile wasn't finding the compilers correctly,
so to aid in future debugging, this adds a parameter to show what
xcompile is doing as it runs.
Run from the command line:

Instead of instructing users to edit xcompile when they want to build
a quark platform, give the build a way to set -march=586 so that
the quark code will build correctly. The Quark processor does not
support the instructions introduced with the Pentium 6 architecture.

The compiler really supports a whole line of ARM CPUs, not just
ARMv7a:
arm-eabi-gcc: note: valid arguments to '-march=' are: armv2 armv2a
armv3 armv3m armv4 armv4t armv5 armv5e armv5t armv5te armv6 armv6-m
armv6j armv6k armv6s-m armv6t2 armv6z armv6zk armv7 armv7-a armv7-m
armv7-r armv7e-m armv7ve armv8-a armv8-a+crc iwmmxt iwmmxt2 native
So let's reflect this in the cross compiler name.
