From 8a94357dec452ef32e2037dda37bcc58eb2c64c5 Mon Sep 17 00:00:00 2001 From: jb Date: Tue, 10 Mar 1998 06:56:16 +0000 Subject: Import a sanitized version of jdp's crt1.c from i386-elf. I have removed the rtld code pending implementation on the alpha. The csu/i386-elf should be renamed as csu/elf and this directory trashed. Consider this a temporary implementation. --- lib/csu/alpha/crt1.c | 63 ++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 lib/csu/alpha/crt1.c (limited to 'lib/csu/alpha/crt1.c') diff --git a/lib/csu/alpha/crt1.c b/lib/csu/alpha/crt1.c new file mode 100644 index 0000000..3ef5d71 --- /dev/null +++ b/lib/csu/alpha/crt1.c @@ -0,0 +1,63 @@ +/*- + * Copyright 1996-1998 John D.
