Fix out of bounds index into VlWide under AstSel
...
When part selecting bits via an AstSel in a VlWide, V3Expand used to do
something akin to:
word_index = lsb / 32;
bit_index = lsb % 32;
result =
wide[word_index + 1] << (32 - bit_index) | wide[word_index] >> bit_index;
The unconditional "+ 1" can cause an out of bounds access into the
VlWide, when the whole of the select is into the most significant word
(i.e.: when word_index is already the most significant word). We now
emit roughly this instead:
lo_word_index = lsb / 32;
bit_index = lsb % 32;
hi_word_index = (lsb + width - 1) / 32;
result =
wide[hi_word_index] << (32 - bit_index) | wide[lo_word_index] >> bit_index;
i.e.: we explicitly calculate which word the MSB of the select falls
into, and address that word, rather than the unconditional + 1. The
shifts ensure we still yield the right result, even if lo_word_index and
hi_word_index are the same.
Note: The actual expression created by V3Expand can be a bit more
complicated as we might need to access 3 words when the result is a
QData, all 3 word indices are calculated explicitly.
