Include module name for area summary stats
2018-06-19 13:47:39 +02:00
Edmond Cote d89560a0ba
Include module name for area summary stats
The PR prints the name of the module when displaying the final area count.

Pros:
- Easier for the user to `grep` for area information about a specific module

Cons:
- Arguably more verbose, less "pretty" than author desires

Verification:

Merge pull request #454 from rqou/emscripten-and-abc
Add option to statically link abc; emscripten fixes
2018-05-19 08:42:45 +02:00
Robert Ou 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).
