/* Do not expand builtin functions (unless explicitly prefixed with
|
|
"__builtin"). 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. */
