23 | /* Do not expand builtin functions (unless explicitly prefixed with |
24 | "__builtin"). Symbian OS code relies on properties of the standard | |
25 | library that go beyond those guaranteed by the ANSI/ISO standard. | |
26 | For example, "memcpy" works even with overlapping memory, like | |
27 | "memmove". We cannot simply set flag_no_builtin in arm.c because | |
28 | (a) flag_no_builtin is not declared in language-independent code, | |
29 | and (b) that would prevent users from explicitly overriding the | |
63c5b495 | 30 | default with -fbuiltin, which may sometimes be useful. |
336bd6ac MM |
31 | |
32 | Make all symbols hidden by default. Symbian OS expects that all | |
33 | exported symbols will be explicitly marked with | |
2ed9e527 MM |
34 | "__declspec(dllexport)". |
35 | ||
36 | Enumeration types use 4 bytes, even if the enumerals are small, | |
37 | unless explicitly overridden. | |
38 | ||
39 | The wchar_t type is a 2-byte type, unless explicitly | |
40 | overridden. */ | |
