      The attached source file has these lines ...

      #pragma clang section data="one_data"
static volatile uint32_t var1 = (uint32_t)(0U);
#pragma clang section data=""

#pragma clang section data="two_data"
static struct sss_tag sss_instance;
#pragma clang section data=""

      Build it ...

      % tiarmclang -S file.c

      Inspect the resulting file.s. Both variables get created. The first one is created in the user-named section. The second one is created in the default section .bss, and not the user-named section.
