ReadSwapShort isn't inlined into myfunc in the below code. Building with:
"llvmc -O3 -S -emit-llvm cmap4.c -clang". Without -clang, it is inlined.
inline __attribute__((always_inline))
unsigned short _OSSwapInt16(unsigned short _data)
{
return ((_data << 8) | (_data >> 8));
}
inline __attribute__((always_inline))
unsigned short ReadSwapShort(unsigned char* data, unsigned int offset)
{
return _OSSwapInt16(*(unsigned short*) &data[offset]);
}
unsigned short myfunc(unsigned char* cmap, unsigned int offset, unsigned short
c)
{
return ReadSwapShort(cmap, offset);
}
