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. --- ChangeLog | 5 +++++ sysdeps/tile/configure | 7 +++++++ sysdeps/tile/configure.ac | 6 ++++++ 3 files changed, 18 insertions(+) create mode 100644 sysdeps/tile/configure create mode 100644 sysdeps/tile/configure.ac diff --git a/ChangeLog b/ChangeLog index 8f7c17603c..344c575192 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2015-04-16 Chris Metcalf + + * sysdeps/tile/configure.ac: New file. + * sysdeps/tile/configure: Regenerated. + 2015-04-15 Adhemerval Zanella * wcsmbs/wcschr.c [WCSCHR] (wcschr): Define as __wcschr.
