optee-os: Refresh GCC 10 patches
The original fix for compiling with GCC 10 had to be reverted because it failed on older versions. Upstream resolved this and re-instituted the fix, so backport that patch series Signed-off-by: Joshua Watt <JPEWhacker@gmail.com> Signed-off-by: Jon Mason <jon.mason@arm.com>

Subject: [PATCH 1/6] mk/compile.mk: fix cc-option macro
|
||||
|
||||
There are (at least) three issues with the cc-option macro:
|
||||
|
||||
1. When COMPILER=clang: when presented with a supported but unused
|
||||
option, Clang emits a warning to stderr (and returns a success code
|
||||
of 0). Therefore it is incorrect to check stderr to determine if an
|
||||
option is supported or not; we should rely on the return status
|
||||
instead.
|
||||
2. When COMPILER=clang, the compile command $(CC$(sm)) contains an
|
||||
equal sign (e.g., clang --target=arm-linux-gnueabihf). This is not
|
||||
expected in the cc-option macro, currently only flags are allowed to
|
||||
potentially contain an equal sign. This messes with the caching of
|
||||
the test result.
|
||||
3. The macro should not cache the return value when an option is not
|
||||
supported. For instance, if we have:
|
||||
A := $(call cc-option,--not-supported,a)
|
||||
B := $(call cc-option,--not-supported,b)
|
||||
...we expect A to be "a" and B to be "b". The current implementation
|
||||
returns "a" in both cases.
|
||||
|
||||
This commit fixes the above problems.

Subject: [PATCH 2/6] Allow use of cc-option in core/arch/arm/arm.mk
|
||||
|
||||
It can be useful to call the cc-option macro when setting flags in
|
||||
core/arch/arm/arm.mk. Unfortunately cc-option is defined in
|
||||
mk/compile.mk which is too late to be useful (core/arch/arm/arm.mk is
|
||||
included by core/core.mk before mk/compile.mk).
|
||||
|
||||
This commit addresses the issue by moving the definition of cc-option
|
||||
to its own file, mk/cc-option.mk, which is then included by
|
||||
core/arch/arm/arm.mk. There is a dependency on the compiler definitions
|
||||
(mk/gcc.mk or mk/clang.mk) and on $(arch-bit-$(sm)) so
|
||||
core/arch/arm/arm.mk is modified accordingly.
|
||||
|
||||
Moving cc-option out of mk/compile.mk means that all non-core
|
||||
submodules would lose the definition unless they include
|
||||
mk/cc-option.mk; the TA dev kit is modified so that TAs can call
|
||||
cc-option from within their sub.mk files. As for other submodules, they
|
||||
are internal and do not use cc-options as of now so they are not
|
||||
modified.

always undefined at the point it is used. Indeed, comp-cflags$(sm) is
