Hello everyone,
I just checked that clone() is only present in i386 Linux RTL but it is not
defined in x86-64. Am I right? Or, I am missing something.

Hi,
When I am compiling to ELF64, the linker is located the .text section at
the address 4MB and the .data at address 6MB. Is there any way to reduce
this 2MB gap between those sections?

Hello,
I am writing my own __FPC_specific_handler() but I can't figure out when
this function is registered. I guess this function is registered to the OS
to be invoked when an exception happens. In the assembler code I have
something like:
.seh_handler __FPC_specific_handler,@unwind
But I am pu

Hello eveyryone,
in my rtl for torokernel, I have to implement "_fpc_local_unwind()" however
I am not sure about the expected behavior of this function. It appers in
the code when I use "Exit" inside a "try finally" structure. I would like
to know what this function should do. So if someone can po
After fixing the assembler code and other issues, e.g., interruption
handlers were not restoring all registers, I observed an speed up of ~12%
with -O2 when running a simple webserver example. That's very impresive!
Thanks for you help, Matias.

Hello everyone,
I am getting an exception when I enable the -O2 optimization. More
precisaily, the line that stars with write_portd is corrupting the data
section. This is the pascal code:
function PciReadDword(const bus, device, func, regnum: UInt32): UInt32;

Hello everyone,
I want to implement the cpu_relax() function in order to use it inside
loops. However before, I would like to know if the fpc compiler is doing an
optimization of this kind.
Kinds regards, Matias.

Hello,
I am not sure why my executable does not contains a .debug_aranges section.
It contains .debug_line and .debug_info. Am I missing some linker flags?
Thanks, Matias.
