My software needs to use 64-bit integers and it causes problems when these are passed to functions. When I use 32-bit integers (unsigned int) everything works well. When i change them to uint64_t type two problems arise:

1. The debugger always shows only lower 32 bits of 64 integers. For example the folllowing code should set "temp64" variable to 0x1122334455667788 value but the debugger shows 0x55667788:

uint64 temp64;

temp64 = 0x1122334455667788LL;

2. When "Addr" variable of uint64_t type is passed to the function "ReadBlock" the "Addr" variable always equals to 0x20004DCC at the entry of the function instead of 0x00000000:

u8 ReadBlock(u8 *buf, uint64_t Addr)
{
....
....
}

if (ReadBlock(Buf, 0))
{
....
....
}

When "Addr" is uint32_t type, the function works ok:

u8 ReadBlock(u8 *buf, uint32_t Addr)
{
....
....
}

if (ReadBlock(Buf, 0))
{
....
....
}

Is it possible there is an error in the compiler or do i do something wrong ?
