Marcelina Kościelnicka 082cbcb4c7 synth_intel: Remove incomplete Arria 10 GX support. 
The techmap rules for this target do not work in the first place (note
lack of >2-input LUT mappings), and if proper support is ever added,
it'd be better placed in the synth_intel_alm backend.

Marcelina Kościelnicka 50d532f01c techmap/shift_shiftx: Remove the "shiftx2mux" special path. 
Our techmap rules for $shift and $shiftx cells contained a special path
that aimed to decompose the shift LSB-first instead of MSB-first in
select cases that come up in pmux lowering.  This path was needlessly
overcomplicated and contained bugs.

Instead of doing that, just switch over the main path to iterate
LSB-first (except for the specially-handled MSB for signed shifts
and overflow handling).  This also makes the code consistent with
shl/shr/sshl/sshr cells, which are already decomposed LSB-first.

Fixes #2346.

Xiretza 916028906a Ensure \A_SIGNED is never used with $shiftx 
It has no effect on the output ($shiftx doesn't perform any sign
extension whatsoever), so an attempt to use it should be caught early.
 2020-08-18 19:36:24 +02:00
Xiretza 928fd40c2e Respect \A_SIGNED for $shift 
This reflects the behaviour of $shr/$shl, which sign-extend their A
operands to the size of their output, then do a logical shift (shift in
0-bits).
