Subject: [PATCH 08/22] Backport: ICE: segmentation fault with
 patchable_function_entry attribute for msp430-elf -mlarge)

2021-10-07  Giuliano Belinassi  <gbelinassi@suse.de>

PR target/87927
	* target-def.h: Initialize TARGET_ASM_{,UN}ALIGNED_P{S,D,T}I_OP.
	Add them to the TARGET_ASM_{,UN}ALIGNED_INT_OP structs.
	* target.def: Enumerate TARGET_ASM_{,UN}ALIGNED_P{S,D,T}I_OP in
	the byte_op hook.
	* target.h: Add psi, pdi, pti to struct asm_int_op definition.
	* targhooks.c (default_print_patchable_function_entry): Assert
	asm_int_op does not return a NULL string.
	* varasm.c (integer_asm_op): Return the op for a partial int type
	when the requested size does not correspond to an integer type.
	* config/msp430/msp430.c: Initialize TARGET_ASM_{,UN}ALIGNED_PSI_OP.
	* doc/tm.texi: Regenerate.
