From da6989f9a5ec774419b7499b6270e60a8afde9df Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Thu, 16 Apr 2015 09:40:21 -0400 Subject: tile: Enable PI_STATIC_AND_HIDDEN This does make ld.so very slightly larger (0.3%) and doesn't seem to actually improve performance; in fact, my limited testing suggested a slight (0.1%) performance decrease (running fork/exec of a no-op program in a loop), but I didn't do enough testing to establish statistical significance. However, Roland agrees that it makes sense to switch tile to using this path, since it's the more standard way. --- sysdeps/tile/configure | 7 +++++++ sysdeps/tile/configure.ac | 6 ++++++ 2 files changed, 13 insertions(+) create mode 100644 sysdeps/tile/configure create mode 100644 sysdeps/tile/configure.ac (limited to 'sysdeps') diff --git a/sysdeps/tile/configure b/sysdeps/tile/configure new file mode 100644 index 0000000..534c7db --- /dev/null +++ b/sysdeps/tile/configure @@ -0,0 +1,7 @@ +# This file is generated from configure.ac by Autoconf.
