071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	341 c_lnotab is an array of unsigned bytes disguised as a Python string. In -O
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	342 mode, SET_LINENO opcodes aren't generated, and bytecode offsets are mapped
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	343 to source code line #s (when needed for tracebacks) via c_lnotab instead.
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	344 The array is conceptually a list of
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	345 (bytecode offset increment, line number increment)
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	346 pairs. The details are important and delicate, best illustrated by example:
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	347
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	348 byte code offset source code line number

071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	355 The first trick is that these numbers aren't stored, only the increments
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	356 from one row to the next (this doesn't really work, but it's a start):
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	357
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	358 0, 1, 6, 1, 44, 5, 300, 300, 11, 1
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	359
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	360 The second trick is that an unsigned byte can't hold negative values, or
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	361 values larger than 255, so (a) there's a deep assumption that byte code
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	362 offsets and their corresponding line #s both increase monotonically, and (b)
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	363 if at least one column jumps by more than 255 from one row to the next, more
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	364 than one pair is written to the table. In case #b, there's no way to know
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	365 from looking at the table later how many were written. That's the delicate
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	366 part. A user of c_lnotab desiring to find the source line number
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	367 corresponding to a bytecode address A should do something like this

071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	371 addr += addr_incr
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	372 if addr > A:

071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	375
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	376 In order for this to work, when the addr field increments by more than 255,
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	377 the line # increment in each pair generated must be 0 until the remaining addr
071c957221ec Backport Tim's checkin 2.201: Thomas Wouters <thomas@python.org> parents: 17939 diff changeset	378 increment is < 256. So, in the example above, com_set_lineno should not (as
