The DATA_SEG_BITS hack was needed for older 32 bit platforms. As a result of this change, Emacs won't work on IRIX 6.5 with IRIX cc, but that platform is so old that SGI itself stopped supporting it in December 2013. If you still need Emacs on IRIX, please either compile with GCC and port the undumping code, or run './configure --with-wide-int'. * configure.ac (DATA_SEG_BITS): Remove. All uses removed. * src/alloc.c (gdb_make_enums_visible): Update to match lisp.h. * src/lisp.h (GCTYPEBITS): Move definition up, and switch to the DEFINE_GDB_SYMBOL_START way to define it. (NONPOINTER_BITS): New macro. (EMACS_INT): Use it. [!USE_LSB_TAG && !WIDE_EMACS_INT]: Fail, and suggest reporting the problem and/or configuring --with-wide-int. (USE_LSB_TAG): Simplify, based on above changes. (gdb_DATA_SEG_BITS): Remove. All uses removed. * src/vm-limit.c (exceeds_lisp_ptr): Remove. All uses removed.
