interface.i: In function 'intPickerButtons':
interface.i:44: error: unable to find a register to spill in class 'FP_REGS'
interface.i:44: error: this is the insn:
(insn 152 151 153 1 (parallel [
(set (subreg:SI (reg:HI 261) 0)
(fix:SI (reg:SF 32 $f0 [260])))
(clobber (scratch:SF))
]) 167 {fix_truncsfsi2_macro} (insn_list:REG_DEP_TRUE 150 (nil))
(expr_list:REG_UNUSED (scratch:SF)
(expr_list:REG_UNUSED (scratch:SF)
(expr_list:REG_DEAD (reg:SF 32 $f0 [260])
(nil)))))
interface.i:44: confused by earlier errors, bailing out
I'll attach the original test case and a somewhat trimmed one, that doesn't
trigger at -O2, though.
