Move report preconditions (bounds, exhaustion, etc) into program
instructions and use a more direct path to the user match callback than
the adaptor functions.
Report handling has been moved to new file src/report.h. Reporting from
EOD now uses the same instructions as normal report handling, rather
than its own.
Jump target tracking in rose_build_bytecode.cpp has been cleaned up.
Specifically, we must set build_context::floatingMinLiteralMatchOffset
to 1 when thew anchored table contains multiple DFAs, as they can
produce unordered matches.
This check was already been done, but too late to affect the generation
of ANCHORED_DELAY instructions.
Replace the RoseLiteral structure with more program instructions; now,
instead of each literal ID leading to a RoseLiteral, it simply has a
program to run (and a delay rebuild program).
This commit also makes some other improvements:
* CHECK_STATE instruction, for use instead of a sparse iterator over a
single element.
* Elide some checks (CHECK_LIT_EARLY, ANCHORED_DELAY, etc) when not
needed.
* Flatten PUSH_DELAYED behaviour to one instruction per delayed
literal, rather than the mask/index-list approach used before.
* Simple program cache at compile time for deduplication.
- cleanups
- add sparse iter instructions
- merge "root" and "sparse iter" programs together
- move program execution to new file program_runtime.h
- simplify EOD execution
- Use program for EOD sparse iterator
- Use program for literal sparse iterator
- Eliminate RoseRole, RosePred, RoseVertexProps::role
- Small performance optimizations
We were using intermediate values int he enum and casting back and forth
with a u32; it is cleaner to just use a u32 and define some special
values.
Silences ICC warning #188: enumerated type mixed with another type.
