From 0030cbf06c669b65e124414af51b5010fc53b760 Mon Sep 17 00:00:00 2001 From: Matthias Urlichs Date: Thu, 23 Jun 2005 00:10:05 -0700 Subject: [PATCH] [PATCH] Turn off sibling call optimization w/ frame pointers Frame pointers are supposed to enable debuggers to reliably tell where a call comes from. That is defeated by GCC's sibling call optimization (aka tail recursion elimination). This patch turns this optimization off when compiling with frame pointers.
