Btw, the following is the ports that default to reload and have no command line option to switch to LRA. config/alpha/alpha.cc:#define TARGET_LRA_P hook_bool_void_false config/avr/avr.cc:#define TARGET_LRA_P hook_bool_void_false config/bfin/bfin.cc:#define TARGET_LRA_P hook_bool_void_false config/c6x/c6x.cc:#define TARGET_LRA_P hook_bool_void_false config/cris/cris.cc:#define TARGET_LRA_P hook_bool_void_false config/epiphany/epiphany.cc:#define TARGET_LRA_P hook_bool_void_false config/fr30/fr30.cc:#define TARGET_LRA_P hook_bool_void_false config/frv/frv.cc:#define TARGET_LRA_P hook_bool_void_false config/h8300/h8300.cc:#define TARGET_LRA_P hook_bool_void_false config/ia64/ia64.cc:#define TARGET_LRA_P hook_bool_void_false config/iq2000/iq2000.cc:#define TARGET_LRA_P hook_bool_void_false config/lm32/lm32.cc:#define TARGET_LRA_P hook_bool_void_false config/m32c/m32c.cc:#define TARGET_LRA_P hook_bool_void_false config/m32r/m32r.cc:#define TARGET_LRA_P hook_bool_void_false config/m68k/m68k.cc:#define TARGET_LRA_P hook_bool_void_false config/mcore/mcore.cc:#define TARGET_LRA_P hook_bool_void_false config/microblaze/microblaze.cc:#define TARGET_LRA_P hook_bool_void_false config/mmix/mmix.cc:#define TARGET_LRA_P hook_bool_void_false config/mn10300/mn10300.cc:#define TARGET_LRA_P hook_bool_void_false config/moxie/moxie.cc:#define TARGET_LRA_P hook_bool_void_false config/msp430/msp430.cc:#define TARGET_LRA_P hook_bool_void_false config/nvptx/nvptx.cc:#define TARGET_LRA_P hook_bool_void_false config/pa/pa.cc:#define TARGET_LRA_P hook_bool_void_false config/rl78/rl78.cc:#define TARGET_LRA_P hook_bool_void_false config/stormy16/stormy16.cc:#define TARGET_LRA_P hook_bool_void_false config/visium/visium.cc:#define TARGET_LRA_P hook_bool_void_false
