Mark Ruvald Pedersen cb0fd451c2 cmake: Toolchain abstraction: Assembly
Introduce toolchain_cc_asm macro to capture toolchain specific flags
related to assembly.

-D_ASMLANGUAGE is kept common for all, assuming -D as define flag is
supported by all compilers (which is almost the case).

No functional change expected.

Clang's flags are compatible with gcc, and are thus inherited.

This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting easier porting to other (commercial) toolchains.

Mark Ruvald Pedersen 63df409906 cmake: Toolchain abstraction: C++
Introduce toolchain_cc_cpp_*-family of macros.

Move the following into the toolchain_cc_cpp_* macros:
 * Common base set of flags
 * C++ standard version
 * RTTI
 * Exceptions

These macros must be implemented by every compiler port.
These macros set the respective flags, but leaves logic and control to
the root CMakeLists.txt file.

No functional change expected.

Mark Ruvald Pedersen 0b3c65feea cmake: Toolchain abstraction: optimizations
Introduce toolchain_cc_optimize_for_* family of macros.
Each macro represents a general optimization class.
Each macro is then responsible for setting an output variable to that
class-of-optimization's flag.
The names of these output variables are decided from the root
CMakeLists.txt.

No functional change expected.

Mark Ruvald Pedersen 01592071f1 cmake: Toolchain abstraction: security
Introduce the first of the toolchain_cc-family of macros:
toolchain_cc_security_fortify and toolchain_cc_security_canaries.

No functional change expected.

Fortify source is not supported by Clang, but this commit retains
current behavior.

This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting easier porting to other (commercial) toolchains.

Marc Herbert aa4ed2ae8c host-gcc: TOOLCHAIN_LIBS += libgcc (copied from compiler/gcc/)
Add missing -lgcc when compiling with ZEPHYR_TOOLCHAIN_VARIANT=host
merely copying some existing code from
'compiler/{clang,gcc}/target.cmake'.

This fixes compilation for the following boards with an x86
microprocessor:

 galileo, minnowboard, qemu_x86, qemu_x86_nommu, up_squared,
 up_squared_sbl

Compilation of the following boards with an X86_IAMCU microcontroller
still fail with a "cannot find -lgcc" error:

 arduino_101, qemu_x86_iamcu, quark_d2000_crb, quark_se_c1000_devboard,
 tinytile

This is _not_ a regression because these boards _already_ failed with
"undefined reference to __udivdi3" and other libgcc symbols.

Sebastian Bøe a0a63ac344 cmake: Split toolchain configuration into pre-and post-DT
Split up the toolchain configuration into two phases, generic and
target. The 'generic' phase configures the toolchain just enough to be
able to preprocess DT files. The 'target' phase completes the
configuration with target-specific configuration.
