    • i386: Handle REG_EH_REGION note · 12fb7712 
      When we split:

(insn 18 17 76 2 (set (reg:SF 88 [ _19 ])
        (float:SF (mem/c:SI (symbol_ref:DI ("d") [flags 0x2]  <var_decl 0x7fd6d8290c60 d>) [1 d+0 S4 A32]))) "x.ii":4:20 170 {*floatsisf2}
     (expr_list:REG_EH_REGION (const_int 2 [0x2])
        (nil)))

to

(insn 94 17 18 2 (set (reg:V4SF 115)
        (vec_merge:V4SF (vec_duplicate:V4SF (float:SF (mem/c:SI (symbol_ref:DI ("d") [flags 0x2]  <var_decl 0x7f346837ac60 d>) [1 d+0 S4 A32])))

     (expr_list:REG_EH_REGION (const_int 2 [0x2])
        (nil)))

we must copy the REG_EH_REGION note to the first insn and split the block
after the newly added insn.  The REG_EH_REGION on the second insn will be
removed later since it no longer traps.

    • x32: Add addr32 prefix to VSIB address · fb055f4b 
      32-bit indices in VSIB address are sign-extended to 64 bits.  In x32,
when 32-bit indices are used as addresses, like in

vgatherdps %ymm7, 0(,%ymm9,1), %ymm6

32-bit indices, 0xf7fa3010, is sign-extended to 0xfffffffff7fa3010 which
is invalid address.  Add addr32 prefix to UNSPEC_VSIBADDR instructions
for x32 if there is no base register nor symbol.
