The functions in this API return information about the operating system or runtime system.
This contains information about the platform ABI such as the size and alignment of C types, the name mangling of global symbols and a list of platform and target specific C preprocessor definitions.
| typedef struct ir_platform_define_t ir_platform_define_t |
| enum ir_platform_type_t |
| char const* ir_platform_default_exe_name | ( | void | ) |
Returns the default executable name for the target (a.out or a.exe).
| ir_platform_define_t const* ir_platform_define_first | ( | void | ) |
Returns the first element in the list of target preprocessor defines.
| char const* ir_platform_define_name | ( | ir_platform_define_t const * | define | ) |
Returns the name of the preprocessor define define.
| ir_platform_define_t const* ir_platform_define_next | ( | ir_platform_define_t const * | define | ) |
Returns the element following define in the list of target preprocessor defines or NULL if define is the last element.
| char const* ir_platform_define_value | ( | ir_platform_define_t const * | define | ) |
Returns the value that the proprocessor define define should be defined to.
| ir_platform_type_t ir_platform_intptr_type | ( | void | ) |
Returns C type used for pointer sized integer like intptr_t or size_t.
| unsigned ir_platform_long_long_and_double_struct_align_override | ( | void | ) |
May return an override to long long and double alignment in structs.
This is a special case: Old C compilers had a bug where long long and double where aligned differently inside structs. Some ABIs explicitely stay compatible to this.
| ident* ir_platform_mangle_global | ( | char const * | name | ) |
Returns name mangled for platform.
This usually adds the user_label_prefix ('_' on win32, macOS, "" on ELF based systems) in front of the identifier.
| int ir_platform_pic_is_default | ( | void | ) |
Returns 1 if target should compile position independent code by default.
| int ir_platform_supports_thread_local_storage | ( | void | ) |
Returns 1 if target and platform support thread local storage, 0 otherwise.
| unsigned ir_platform_type_align | ( | ir_platform_type_t | type | ) |
Returns the alignment of the C type type in bytes.
| ir_mode* ir_platform_type_mode | ( | ir_platform_type_t | type, |
| int | is_signed | ||
| ) |
Returns an ir_mode matching for the type type.
| unsigned ir_platform_type_size | ( | ir_platform_type_t | type | ) |
Returns the size of the C type type in bytes.
| char ir_platform_user_label_prefix | ( | void | ) |
Returns the character "normal" linker identifiers are prefixed with.
| ir_type* ir_platform_va_list_type | ( | void | ) |
Returns type used for va_list values.
May be a pointer type, a struct type or NULL if the backend does not support variadic functions.
| int ir_platform_wchar_is_signed | ( | void | ) |
Returns true if the wchar_t type is signed.
| ir_platform_type_t ir_platform_wchar_type | ( | void | ) |
Returns the C type corresponding to wchar_t.
Note that technically in C++ wchar_t is an own type; this function will return a type with the same characteristics anyway.
