Merge pull request from rqou/emscripten-and-abc
Add option to statically link abc; emscripten fixes
2018-05-19 08:42:45 +02:00

bea71e71ca Force abc to align memory to 8 bytes
Apparently abc has a memory pool implementation that by default returns
memory that is unaligned. There is a workaround in the abc makefile that
uses uname to look for "arm" specifically and then sets the alignment.
However, ARM is not the only platform that requires proper alignment
(e.g. emscripten does too). For now, pessimistically force the alignment
for 8 bytes all the time (somehow 4 wasn't enough for fixing emscripten
despite being approximately a 32-bit platform).

faac2c5595 Avoid mixing module port declaration styles in ice40 cells_sim.v
The current code requires workarounds for several simulators
For modelsim, the file must be compiled with -mixedansiports and
xsim needs --relax.
