[LLVMdev] Defining a pointer to a specific memory address?
...making a little sample C program to see how llvm-gcc generated the access, and it used this:
volatile store i32 -1430532899, i32* inttoptr (i64 4294963200 to i32*), align 4
for this C code:
typedef volatile unsigned int AT91_REG;// Hardware register definition
#define AT91_CAST(a) (a)
#define AT91C_BASE_SYS (AT91_CAST(AT91_REG*) 0xFFFFF000) // (SYS) Base Address
void
main()
{
*AT91C_BASE_SYS = 0xaabbccdd;
}
Is there any way to do the equivalent with a global?
Thanks,
Rick
