Hi all,
Looking at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcechp40/html/ccrefPredefinedPreprocessorIdentifiers.asp
It says:
*_M_ARM* Defined as 4 for ARM.
*_M_ARMT* Defined as 4 for Thumb.
But, testing with MSVC with the following mini-program,
and with changing the target processor type in the project settings,
I see that _M_ARM and _M_ARMT get defined to 4 or 5 depending on
what arm arch is selected. Also, _M_ARMT is only defined if a thumb
enabled arch is selected (armv4t and armv5t).
Therefore I am committing the attached patches, to make us define the
same values too.
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
printf ("_M_ARM = %d\n", _M_ARM);
#ifdef _M_ARMT
printf ("_M_ARMT = %d\n", _M_ARMT);
#else
printf ("_M_ARMT not defined\n");
#endif
return 0;
}
Cheers,
Pedro Alves
