[PATCH v4 1/2] MIPS: unaligned load: use SImode for SUBREG if OK (PR98996) [PATCH v4 2/2] ada: add 128bit operation for MIPS N32 and N64

Browse Source 
gcc/ChangeLog:

	PR target/98996
	* config/mips/mips.c (mips_expand_ext_as_unaligned_load):
	If TARGET_64BIT and dest is SUBREG, we check the width, if it
	equal to SImode, we use SImode operation, just like what we are
	doing for REG one.

gcc/ada/ChangeLog:

	PR ada/98996
	* Makefile.rtl: <mips*-*-linux*>
	add 128Bit operation file for MIPS N64 and N32 to
	LIBGNAT_TARGET_PAIRS and EXTRA_GNATRTL_NONTASKING_OBJS
