The gcc-poison-parameters was added specifically to deal with an issue on ppc targets and a bug when we build with -Os -frename-registers.
This bug below reports the issue and is fixed in gcc-4.6.x: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44618 Signed-off-by: Kumar Gala <ga...@kernel.crashing.org> --- .../gcc/gcc-4.6/gcc-poison-parameters.patch | 76 -------------------- 1 files changed, 0 insertions(+), 76 deletions(-) delete mode 100644 meta/recipes-devtools/gcc/gcc-4.6/gcc-poison-parameters.patch diff --git a/meta/recipes-devtools/gcc/gcc-4.6/gcc-poison-parameters.patch b/meta/recipes-devtools/gcc/gcc-4.6/gcc-poison-parameters.patch deleted file mode 100644 index 58bf32f..0000000 --- a/meta/recipes-devtools/gcc/gcc-4.6/gcc-poison-parameters.patch +++ /dev/null @@ -1,76 +0,0 @@ -Upstream-Status: Pending - -gcc: add poison parameters detection - -Add the logic that, if not configured with "--enable-target-optspace", -gcc will meet error when build target app with "-Os" option. -This could avoid potential binary crash. - -Signed-off-by: Dongxiao Xu <dongxiao...@intel.com> - -Index: gcc-4.6.0/gcc/config.in -=================================================================== ---- gcc-4.6.0.orig/gcc/config.in -+++ gcc-4.6.0/gcc/config.in -@@ -150,6 +150,12 @@ - #endif - - -+/* Define to enable target optspace support. */ -+#ifndef USED_FOR_TARGET -+#undef ENABLE_TARGET_OPTSPACE -+#endif -+ -+ - /* Define if you want all operations on RTL (the basic data structure of the - optimizer and back end) to be checked for dynamic type safety at runtime. - This is quite expensive. */ -Index: gcc-4.6.0/gcc/configure -=================================================================== ---- gcc-4.6.0.orig/gcc/configure -+++ gcc-4.6.0/gcc/configure -@@ -26434,6 +26434,13 @@ $as_echo "#define ENABLE_LIBQUADMATH_SUP - fi - - -+if test x"$enable_target_optspace" != x; then : -+ -+$as_echo "#define ENABLE_TARGET_OPTSPACE 1" >>confdefs.h -+ -+fi -+ -+ - # Configure the subdirectories - # AC_CONFIG_SUBDIRS($subdirs) - -Index: gcc-4.6.0/gcc/configure.ac -=================================================================== ---- gcc-4.6.0.orig/gcc/configure.ac -+++ gcc-4.6.0/gcc/configure.ac -@@ -4907,6 +4907,11 @@ if test "${ENABLE_LIBQUADMATH_SUPPORT}" - fi - - -+AC_SUBST(enable_target_optspace) -+if test x"$enable_target_optspace" != x; then -+ AC_DEFINE(ENABLE_TARGET_OPTSPACE, 1, [Define to enable target optspace support.]) -+fi -+ - # Configure the subdirectories - # AC_CONFIG_SUBDIRS($subdirs) - -Index: gcc-4.6.0/gcc/opts.c -=================================================================== ---- gcc-4.6.0.orig/gcc/opts.c -+++ gcc-4.6.0/gcc/opts.c -@@ -605,6 +605,10 @@ default_options_optimization (struct gcc - maybe_set_param_value (PARAM_MIN_CROSSJUMP_INSNS, - default_param_value (PARAM_MIN_CROSSJUMP_INSNS), - opts->x_param_values, opts_set->x_param_values); -+#ifndef ENABLE_TARGET_OPTSPACE -+ if (optimize_size == 1) -+ error ("Do not use -Os option if --enable-target-optspace is not set."); -+#endif - - /* Allow default optimizations to be specified on a per-machine basis. */ - maybe_default_options (opts, opts_set, -- 1.7.3.4 _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
