annotate z80_to_x86.h @ 572:0f32f52fc98e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make some small changes in trans so that it is more likely to produce the same output as mustrans when given misbehaving programs. Add lea to testcases.txt. Improve the output of comparetest.py so that known issues can easily be separated from new ones.
