IA-32/x86-64

    +
  • + The new -fsplit-stack option permits programs to + use a discontiguous stack. This is useful for threaded + programs, in that it is no longer necessary to specify the + maximum stack size when creating a thread. This feature is + currently only implemented for 32-bit and 64-bit x86 GNU/Linux + targets. +
  • Support for emitting profiler counter calls before function prologues. This is enabled via a new command-line option -mfentry.
  • The default setting (when not optimizing for size) for 32-bit - Linux and Darwin x86 targets has been changed to + GNU/Linux and Darwin x86 targets has been changed to -fomit-frame-pointer. The default can be reverted to -fno-omit-frame-pointer by configuring GCC with the --enable-frame-pointer configure option.
