Hi, We've removed all uses of TARGET_FLT_EVAL_METHOD, so we can remove it and poison it.
Bootstrapped and tested on x86-64 and AArch64. Tested on s390 and m68k to the best of my ability (no execute tests). OK? Thanks, James --- gcc/ 2016-09-30 James Greenhalgh <james.greenha...@arm.com> * config/s390/s390.h (TARGET_FLT_EVAL_METHOD): Delete. * config/m68k/m68k.h (TARGET_FLT_EVAL_METHOD): Delete. * config/i386/i386.h (TARGET_FLT_EVAL_METHOD): Delete. * defaults.h (TARGET_FLT_EVAL_METHOD): Delete. * doc/tm.texi.in (TARGET_FLT_EVAL_METHOD): Delete. * doc/tm.texi: Regenerate. * system.h (TARGET_FLT_EVAL_METHOD): Poison.
