When compiling gcc.target/arm/mve/intrinsics/mve_immediates_1_n.c with
-mthumb -mfloat-abi=hard -march=armv8.1-m.main+mve.fp+fp.dp, the compiler
crashes because:
error: insn does not satisfy its constraints:
(insn 28 14 17 2 (set (reg:V8HI 16 s0 [orig:249 u16 ] [249])
(mem/c:V8HI (pre_modify:SI (reg/f:SI 12 ip [248])
(plus:SI (reg/f:SI 12 ip [248])
(const_int 32 [0x20]))) [1 u16+0 S16 A64])) "arm_mve.h":17113:10 3011 {*mve_movv8hi}
(expr_list:REG_INC (reg/f:SI 12 ip [248])
(nil)))
during RTL pass: reload
We are trying to generate:
vldrh.16 q3, [ip], #14
but the constraint check fails because ip is not a low reg.
This patch replaces LAST_LO_REGNUM by LAST_ARM_REGNUM in
mve_vector_mem_operand and avoids the ICE.
