◆ getTypeString()
|
static |
The XCore ABI includes a type information section that communicates symbol type information to the linker.
The linker uses this information to verify safety/correctness of things such as array bound and pointers et al. The ABI only requires C (and XC) language modules to emit TypeStrings. This type information (TypeString) is emitted into meta data for all global symbols: definitions, declarations, functions & variables.
The TypeString carries type, qualifier, name, size & value details. Please see 'Tools Development Guide' section 2.16.2 for format details: https://www.xmos.com/download/public/Tools-Development-Guide%28X9114A%29.pdf The output is tested by test/CodeGen/xcore-stringtype.c.
