| Description |
|
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. |
