Hi,
I noticed, that the builtin functions for mingw (at least for 64-bit
Windows) are not correct in return type. See msdn
http://msdn2.microsoft.com/en-us/library/xwy0k9bb.aspx.
The return type for those targets (i?86-pc-mingw32 and x86_64-pc-mingw32)
is a intptr_t, but a 'int' for other targets. For mingw 32-bit this does
not hurt, but for the 64-bit variant it is a failure.
So my question is: How should I express in builtins.def and
builtin-types.def this target specific modifications?
I see two different approaches for this:
a) Add in builtin-types.h a '#if defined(TARGET_64BIT_MS_ABI) &&
TARGET_64BIT_MS_ABI != 0' to add a specific function type and use in
bultins.def this function type.
b) Add in target mingw and new macro specifying the return type for
builtins. Add to default.h the standard value and add in builtin-types.def
the function type and use it in builtin.def
May somebody could give me advice, how it would be best to introduce this.
