[Ada] Add support for Ada.Execution_Time on linux
Arnaud Charlet

Tue Oct 12 10:38:00 GMT 2010
Implement CPU clocks on linux using the underlying POSIX.1b Realtime
Extensions library, based on function clock_gettime using the
CLOCK_THREAD_CPUTIME_ID.
The following test should compile with no message and execute quietly,
showing that the CPU clock is always lower than the wall clock.
with Ada.Execution_Time; use Ada.Execution_Time;
with Ada.Real_Time; use Ada.Real_Time;
with Ada.Text_IO; use Ada.Text_IO;
procedure Check_CPU_Clock is
task type T;
N : Integer := 0;
task body T is
Time_Init, Time_End : Time;
CPU_Init, CPU_End : CPU_Time;
begin
Time_Init := Ada.Real_Time.Clock;
CPU_Init := Ada.Execution_Time.Clock;
for Index in 1 .. 100_000_000 loop
N := N + 1;
N := N - 2;
end loop;
CPU_End := Ada.Execution_Time.Clock;
Time_End := Ada.Real_Time.Clock;
if Time_End - Time_Init <= CPU_End - CPU_Init then
Put_Line ("Unexpected measurements");
end if;
end T;
Tasks : array (1 .. 10) of T;
begin
null;
end Check_CPU_Clock;
Tested on x86_64-pc-linux-gnu, committed on trunk
2010-10-12 Jose Ruiz <ruiz@adacore.com>
* a-exetim-default.ads, a-exetim-posix.adb: New.
* gcc-interface/Makefile.in (LIBGNAT_TARGET_PAIRS for linux): Use the
POSIX Realtime support to implement CPU clocks.
(EXTRA_GNATRTL_TASKING_OBJS for linux): Add the a-exetim.o object
to the tasking library.
(THREADSLIB): Make the POSIX.1b Realtime Extensions library (librt)
available for shared libraries.
* gcc-interface/Make-lang.in: Update dependencies.
