Hello,
I have a problem that assembler files assembled by GCC issue errors due
to incomplete architecture and FPU options which should be provided by
the assembler command line and not as directives in the file. For example:
arm-rtems6-gcc -save-temps -c test.c -mthumb -march=armv8-a+crc+simd
-mfloat-abi=hard -wrapper echo
/tmp/sh/rtems/6/lib/gcc/arm-rtems6/10.2.1/cc1 -E -quiet
-D__USES_INITFINI__ test.c -mthumb -mfloat-abi=hard
-march=armv8-a+crc+simd -fpch-preprocess -o test.i
/tmp/sh/rtems/6/lib/gcc/arm-rtems6/10.2.1/cc1 -fpreprocessed test.i
-quiet -dumpbase test.c -mthumb -mfloat-abi=hard -march=armv8-a+crc+simd

The assembler is called without the "+simd". In Armv7-A and Armv7-R the
FPU was selected by -mfpu options.
How is your compiler configured (output of gcc -v)?
arm-rtems6-gcc -v
Using built-in specs.
