To access global variables in a PIC environment you need to get the
value of the program counter. "call" puts the value on the stack and
jumps to the label. You don't want to jump, just push the program
counter, so you declare a label immedeately after the call instruction.
The "pop ebx" after it retrieves the pushed program counter from the
stack again in ebx. So this code is correct. The reason why it
didn't compile was case sensitivity of the ATT assembler reader,
which Jonas did correct.
Jonas did disable it on Darwin as it apparently still did not work
for him. It has to be the Darwin PIC code, allthough to the eye it
seems correct to me.
This call and pop is old-style PIC and not good for new cpus because
it breaks the call-stack. Please use the new style that calls a
function (fpc_geteipasebx). This also generated by the compiler. See
i386/cgcpu.pas and search for g_maybe_got_init.
