This patch adds support for defining the ABC location at runtime instead of at compile time. This is helpful in build systems like bazel which do not have stable locations for binaries or directories during the compilation phase.

This change should be backwards compatible with the existing behavior.

4 years agoxilinx: Fix attributes_test.ys

xilinx: Fix attributes_test.ys

This test pretty much passes by accident — the `prep` command runs
memory_collect without memory_dff first, which prevents merging read
register into the memory, and thus blocks block RAM inference for a
reason completely unrelated to the attribute.

The attribute setting didn't actually work because it was set on the
containing module instead of the actual memory.

memory_dff: Fix needlessly duplicating enable bits.

When the register being merged into the EN signal happens to be a $sdff,
the current code creates a new $mux for every bit, even if they happen
to be identical (as is usually the case), preventing proper grouping
further down the flow.  Fix this by adding a simple cache.

Fixes #2409.
