    • FT32 makes use of multiple address spaces. · a297ccb5 
      
FT32 makes use of multiple address spaces. When trying to inspect
objects in GDB, GDB was treating them as a straight "const". The cause
seems to be in GCC DWARF2 output.

This output is handled in gcc/gcc/dwarf2out.c, where modified_type_die()
checks that TYPE has qualifiers CV_QUALS. However while TYPE has
ADDR_SPACE qualifiers, the modified_type_die() explicitly discards the
ADDR_SPACE qualifiers.

This patch retains the ADDR_SPACE qualifiers as modified_type_die()
outputs the DWARF type tree.  This allows the types to match, and correct
type information for the object is emitted.

    • [Arm] Cleanup IT attributes · 113c53c3 
      A recent change to remove the movdi_vfp_cortexa8 meant that ldrd was used in

latent issue, change the default of predicable_short_it to "no" so that only

patterns that need the attribute, and omitting predicable_short_it is no longer
causing issues.

    • PR82816: Widening multiplies of bitfields · 9134df2c 
      In this PR we tried to create a widening multiply of two 3-bit numbers,
but that isn't a widening multiply at the optab/rtl level, since both
the input and output still have the same mode.

We could trap this either in is_widening_mult_p or (as the patch does)
in the routines that actually ask for an optab.  The latter seemed
more natural since is_widening_mult_p doesn't otherwise care about modes.
