From 490e84f5e146485a26dea2f41279a4ff13aaca05 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sun, 4 Feb 2018 15:34:18 +0000 Subject: tile: add basic support for tilegx This adds basic support for tile architecture. Only static binaries, no ld.so or threading support. Tested with qemu-tilegx only. --- libc/sysdeps/linux/tile/sys/ptrace.h | 198 +++++++++++++++++++++++++++++++++++ 1 file changed, 198 insertions(+) create mode 100644 libc/sysdeps/linux/tile/sys/ptrace.h (limited to 'libc/sysdeps/linux/tile/sys/ptrace.h') diff --git a/libc/sysdeps/linux/tile/sys/ptrace.h b/libc/sysdeps/linux/tile/sys/ptrace.h new file mode 100644 index 000000000..94fe60f6f --- /dev/null +++ b/libc/sysdeps/linux/tile/sys/ptrace.h @@ -0,0 +1,198 @@ +/* `ptrace' debugger support interface.
