Subject: arm: Use E_FOOmode instead of FOOmode in arm_preferred_simd_mode
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7e7352b2ad089ea68d689f3b79d93e3ee26326f7;p=gcc.git

arm: Use E_FOOmode instead of FOOmode in arm_preferred_simd_mode

gcc-4.8.5 does not accept case clauses with non-literal type, which
happens for "QImode" as it expands to (scalar_int_mode
((scalar_int_mode::from_int) E_QImode)).

Use E_QImode instead in arm_preferred_simd_mode, to fix the
build. Same for HImode, SImode, HFmode and SFmode as introduced by a
recent patch.

	* config/arm/arm.c (arm_preferred_simd_mode): Use E_FOOmode
	instead of FOOmode.
