MIPS: math-emu: do not use bools for arithmetic
[ Upstream commit 8535f2ba0a9b971df62a5890699b9dfe2e0d5580 ]
GCC-7 complains about a boolean value being used with an arithmetic
AND:
arch/mips/math-emu/cp1emu.c: In function 'cop1Emulate':
arch/mips/math-emu/cp1emu.c:838:14: warning: '~' on a boolean expression [-Wbool-operation]
fpr = (x) & ~(cop1_64bit(xcp) == 0); \
^
arch/mips/math-emu/cp1emu.c:1068:3: note: in expansion of macro 'DITOREG'
DITOREG(dval, MIPSInst_RT(ir));
^~~~~~~
arch/mips/math-emu/cp1emu.c:838:14: note: did you mean to use logical not?
fpr = (x) & ~(cop1_64bit(xcp) == 0); \
Since cop1_64bit() returns and int, just flip the LSB.
