From eb169ea5a89909b90794e0388f89d6d372754e46 Mon Sep 17 00:00:00 2001 From: Nao Pross Date: Thu, 5 Oct 2017 16:09:59 +0200 Subject: Move test units to z80/tests, and drivers are now statically linked Makefiles for the test units were getting messier, so now drivers (that need to be tested) are statically compiled in their own folder under z80/drivers. The kernel makefile and is now broken since everything has been moved. --- sw/z80/drivers/build/ctc.asm | 52 +++++ sw/z80/drivers/build/ctc.lst | 52 +++++ sw/z80/drivers/build/ctc.rel | 19 ++ sw/z80/drivers/build/ctc.sym | 27 +++ sw/z80/drivers/build/pio.asm | 234 ++++++++++++++++++++++ sw/z80/drivers/build/pio.lst | 234 ++++++++++++++++++++++ sw/z80/drivers/build/pio.rel | 87 ++++++++ sw/z80/drivers/build/pio.sym | 36 ++++ sw/z80/drivers/build/usart.asm | 440 +++++++++++++++++++++++++++++++++++++++++ sw/z80/drivers/build/usart.lst | 440 +++++++++++++++++++++++++++++++++++++++++ sw/z80/drivers/build/usart.rel | 184 +++++++++++++++++ sw/z80/drivers/build/usart.sym | 38 ++++ 12 files changed, 1843 insertions(+) create mode 100644 sw/z80/drivers/build/ctc.asm create mode 100644 sw/z80/drivers/build/ctc.lst create mode 100644 sw/z80/drivers/build/ctc.rel create mode 100644 sw/z80/drivers/build/ctc.sym create mode 100644 sw/z80/drivers/build/pio.asm create mode 100644 sw/z80/drivers/build/pio.lst create mode 100644 sw/z80/drivers/build/pio.rel create mode 100644 sw/z80/drivers/build/pio.sym create mode 100644 sw/z80/drivers/build/usart.asm create mode 100644 sw/z80/drivers/build/usart.lst create mode 100644 sw/z80/drivers/build/usart.rel create mode 100644 sw/z80/drivers/build/usart.sym (limited to 'sw/z80/drivers/build') diff --git a/sw/z80/drivers/build/ctc.asm b/sw/z80/drivers/build/ctc.asm new file mode 100644 index 0000000..838756a --- /dev/null +++ b/sw/z80/drivers/build/ctc.asm @@ -0,0 +1,52 @@ +;-------------------------------------------------------- +;
