That's the\nonly change relative to v1.\n\nSo the only part that needs approval is this rs6000/aix.h change.\n\n---------------------------------------------------------------------------\n\nThis patch removes or replaces the remaining uses of HAVE_GNU_AS:\n\n* gcc.cc (asm_options) has a sub-spec to map the gcc -v/-w/-I options to\n their assembler equivalents. It is replaced by ASM_V_SPEC, defaulting\n to the gas version. Non-gas configurations define their own versions.\n\n* Darwin has ASM_OPTIONS which is identical to the default ASM_V_SPEC\n and can just be removed.\n\n* sol2.h currently handles -v in ASM_SPEC_BASE. This patch moves this\n to an Solaris-as only version of ASM_V_SPEC. This also handles the\n gcc -w -> as -n mapping. The spec doesn't pass on -I, though:\n preprocessing .S files is handled by gcc itself, the -I option is only\n used for gas' .include directive which as doesn't support. Solaris as\n instead could handle preprocessing by passing the source through cpp\n when the -P option is given. It also uses -D/-U/-I for that.\n\n* ia64/hpux.h guards AS_NEEDS_DASH_FOR_PIPED_INPUT with !HAVE_GNU_AS,\n but according to install.texi ia64-*-hpux* requires gas so this can\n just go.\n\n* nvptx/nvptx.h handles the mapping in ASM_SPEC. This is done in\n ASM_V_SPEC now. The nvptx as has no equivalents of -w and -I.\n\n* AIX as only supports -v and -W, so rs6000/aix.h gets a matching\n ASM_V_SPEC when as is in use.\n\nOk for trunk?\n\n\tRainer", "diff": "# HG changeset patch\n# Parent 4b212240719bda857db3450c6acbb5f518fdb2c0\nRemove HAVE_GNU_AS\n\ndiff --git a/gcc/config.in b/gcc/config.in\n--- a/gcc/config.in\n+++ b/gcc/config.in\n@@ -1616,12 +1616,6 @@\n #endif\n \n \n-/* Define to 1 if using GNU as. */\n-#ifndef USED_FOR_TARGET\n-#undef HAVE_GNU_AS\n-#endif\n-\n-\n /* Define if your system supports gnu indirect functions. */\n #ifndef USED_FOR_TARGET\n #undef HAVE_GNU_INDIRECT_FUNCTION\ndiff --git a/gcc/config/darwin.h b/gcc/config/darwin.h\n--- a/gcc/config/darwin.h\n+++ b/gcc/config/darwin.h\n@@ -663,21 +663,12 @@ extern GTY(()) int darwin_ms_struct;\n #define ASM_MMACOSX_VERSION_MIN_SPEC \" %<asm_macosx_version_min=* \"\n #endif\n \n-#if HAVE_GNU_AS\n-/* The options are added in gcc.cc for this case. */\n-#define ASM_OPTIONS \"\"\n-#else\n-/* When we detect that we're cctools or llvm as, we need to insert the right\n- additional options.
