The goal of this patch is to move functionality related to constructing
the thread entry points and then invoking them out of V3EmitC (and into
V3Partition). The long term goal being enabling V3EmitC to emit
functions partitioned based on header dependencies. V3EmitC having to
deal with only AstCFunc instances and no other magic will facilitate
this.
In this patch:
- We construct AstCFuncs for each thread entry point in
V3Partition::finalize and move AstMTaskBody nodes under these functions.
- Add the invocation of the threads as text statements within the
AstExecGraph, so they are still invoked where the exec graph is located.
(the entry point functions are still referenced via AstCCall or
AstAddOrCFunc, so lazy declarations of referenced functions are created
automatically).
- Explicitly handle MTask state variables (VlMTaskVertex in
verilated_threads.h) within Verilator, so no need to text bash a lot of
these any more (some text refs still remain but they are all created
next to each other within V3Partition.cpp).
The effect of all this on the emitted code should be nothing but some
identifier/ordering changes. No functional change intended.
* Add detailed location to XML output
* Fixing build failures
* less cryptic regulary expressions
* correcting typo in test
* Adding file letter to the location attribute, and cleaning up the regular expression in the tests.
* Add remaining test expected output files for XML changes
* spacing fix, adding documentation on changes
* Add more directives to configuration files
Allow to set the same directives in configuration files that can also
be set by comment attributes (such as /* verilator public */ etc).
* Add support for lint messsage waivers
Add configuration file switch '-match' for lint_off. It takes a string
with wildcards allowed and warnings will be matched against it (if
rule and file also match). If it matches, the warning is waived.
