Hi Philip
The process I use is as follows (simplified from actual, error checking
removed etc)
// set we want code in memory
tcc_set_output_type(state, TCC_OUTPUT_MEMORY);
// compile the program
tcc_compile_string(state, Program);
// Add symbols for functions in current program, if any
tcc_add_symbol(state, "MyHostFunction", TccHostFunction);
// Get size of compiled code
int Size = tcc_relocate(state, NULL);
// Create some memory to place it in
if (Size > 0) {
void *pMem = malloc(Size);
// Call relocate again, and it will place memory we pass
int err = tcc_relocate(state, pMem);
}
// Get function address, it will be inside pMem
pFunction = tcc_get_symbol(state, "FunctionName");
Cheers
.Richard

I am emulating a fantasy computer based on a
late 1980s computer. I did not want to write my own C compiler for this
fantasy computer so I want to port TCC. However the main road block I
have encountered is controlling where TCC compiles when it compiles to
memory. For this emulator I need to control specifically where in the
block of memory the code is located. With the TO_MEMORY option can I
somehow change where in memory the binary code is placed?
Thanks,
Philip
