Subject: [kvm-unit-tests PATCH v3 7/7] lib/linux/const.h: test for `__ASSEMBLER__` as well
Date: Tue, 7 Mar 2023 10:10:51 +0100 [thread overview]
Message-ID: <20230307091051.13945-8-mhartmay@linux.ibm.com> (raw)
In-Reply-To: <20230307091051.13945-1-mhartmay@linux.ibm.com>
On s390x we're using the preprocessor for generating our linker scripts
out of assembly files. The macro `__ASSEMBLER__` is defined with value 1
when preprocessing assembly language using gcc. [1] Therefore, let's
check for the macro `__ASSEMBLER__` in `lib/linux/const.h` as well. Thus
we can use macros that makes use of the `_AC` or `_AT` macro in the
"linker scripts".
