Symbian OS code relies on properties of the standard library that go beyond those guaranteed by the ANSI/ISO standard. For example, "memcpy" works even with overlapping memory, like "memmove". We cannot simply set flag_no_builtin in arm.c because (a) flag_no_builtin is not declared in language-independent code, and (b) that would prevent users from explicitly overriding the default with -fbuiltin, which may sometimes be useful. Make all symbols hidden by default. Symbian OS expects that all exported symbols will be explicitly marked with "__declspec(dllexport)". Enumeration types use 4 bytes, even if the enumerals are small, unless explicitly overridden. The wchar_t type is a 2-byte type, unless explicitly overridden. */ #define CC1_SPEC \ "%{!fbuiltin:%{!fno-builtin:-fno-builtin}} " \ "%{!fvisibility=*:-fvisibility=hidden} " \ "%{!fshort-enums:%{!fno-short-enums:-fno-short-enums}} " \ "%{!fshort-wchar:%{!fno-short-wchar:-fshort-wchar}} " #define CC1PLUS_SPEC CC1_SPEC /* Symbian OS does not use crt*.o, unlike the generic unknown-elf configuration. */ #undef STARTFILE_SPEC #define STARTFILE_SPEC "" #undef ENDFILE_SPEC #define ENDFILE_SPEC "" /* Do not link with any libraries by default.
