And the VAX port surely is not a tier 1 GCC target \nanyway.\n\n Maciej\n---\n gcc/config/vax/vax.cc | 6 ++----\n 1 file changed, 2 insertions(+), 4 deletions(-)\n\ngcc-vax-nonindexed-address-xexp-reg.patch", "diff": "Index: gcc/gcc/config/vax/vax.cc\n===================================================================\n--- gcc.orig/gcc/config/vax/vax.cc\n+++ gcc/gcc/config/vax/vax.cc\n@@ -1811,7 +1811,6 @@ indirectable_address_p (rtx x, bool stri\n static bool\n nonindexed_address_p (rtx x, bool strict)\n {\n- rtx xfoo0;\n if (REG_P (x))\n {\n if (! reload_in_progress\n@@ -1823,11 +1822,10 @@ nonindexed_address_p (rtx x, bool strict\n return true;\n if (indirectable_address_p (x, strict, false))\n return true;\n- xfoo0 = XEXP (x, 0);\n- if (MEM_P (x) && indirectable_address_p (xfoo0, strict, true))\n+ if (MEM_P (x) && indirectable_address_p (XEXP (x, 0), strict, true))\n return true;\n if ((GET_CODE (x) == PRE_DEC || GET_CODE (x) == POST_INC)\n- && BASE_REGISTER_P (xfoo0, strict))\n+ && BASE_REGISTER_P (XEXP (x, 0), strict))\n return true;\n return false;\n }\n", "prefixes": [ "committed" ] }
