Petter Reinholdtsen 89d360aa4a Rewrote Linux edition of proc_self_dirname() to handle any symlink length. 
This make sure the method work also when the program is located in
deep or long file paths, longer than both PATH_MAX and "getconf
PATH_MAX .".  Use the same code on GNU Hurd, where it now work.

I am not sure how to test this in a platform independent way.

Robert O'Callahan 290fb0556d Prevent race on `num_active_worker_threads_`. 
The core issue here is that we need to ensure `num_active_worker_threads_`
is read before incrementing `done_workers`. See the comments
added in this PR to explain why, and why the resulting code is
race-free.

Merge pull request #5728 from povik/tcl-set-result 
Replace deprecated Tcl API to fix use-after-free
 2026-03-06 13:36:48 +00:00
Martin Povišer 167c6c4585 Replace deprecated Tcl API to fix use-after-free 
Under Tcl 9.0 the Tcl_SetResult utility is a macro:

	#define Tcl_SetResult(interp, result, freeProc) \
		do { \
		    const char *__result = result; \
		    Tcl_FreeProc *__freeProc = freeProc; \
		    Tcl_SetObjResult(interp, Tcl_NewStringObj(__result, -1)); \
		    if (__result != NULL && __freeProc != NULL && __freeProc != TCL_VOLATILE) { \
			if (__freeProc == TCL_DYNAMIC) { \
			    Tcl_Free((char *)__result); \
			} else { \
			    (*__freeProc)((char *)__result); \
			} \
		    } \
		} while(0)

Temporaries constructed as part of the 'result' expression will be
dropped before the 'result' pointer is used. What was safe when
Tcl_SetResult was a function isn't safe with the macro definition.
Transition away from deprecated SetResult to calling
SetObjResult/MewStringObj directly.

expensive for huge designs.

Natalia cf511628b0 modify generator for pyosys/wrappers.cc instead of headers 2026-01-18 02:11:09 -08:00
Natalia fb864e91ee Add Design::run_pass() API for programmatic pass execution 
This commit adds a new run_pass() method to the RTLIL::Design class,
providing a convenient API for executing Yosys passes programmatically.

This is particularly useful for PyYosys users who want to run passes
on a design object without needing to manually construct Pass::call()
invocations. The method wraps Pass::call() with appropriate logging
to maintain consistency with command-line pass execution.

Example usage (from Python):
    design = ys.Design()
    # ... build or load design ...
    design.run_pass("hierarchy")
    design.run_pass("proc")
    design.run_pass("opt")

Changes:
- kernel/rtlil.h: Add run_pass() method declaration
- kernel/rtlil.cc: Implement run_pass() method
- tests/unit/kernel/test_design_run_pass.cc: Add unit tests

Robert O'Callahan a6d696ba2b Give `IdString` a default move constructor and make it a POD type. 
Now that we're not refcounting `IdString`, it can use the default move constructor.

in the standard C++ ABI.

Robert O'Callahan 46cb05c471 Pass IdString by value instead of by const reference. 
When IdString refcounting was expensive, it made sense to pass it by const reference
instead of by value, to avoid refcount churn. Now that IdString is not refcounted,
it's slightly more efficient to pass it by value.

Robert O'Callahan b23dc345ae Make it safe to access .c_str() for autoidx IDs in a multithreaded context 2025-11-25 22:49:41 +00:00
Robert O'Callahan 948001f39f Merge the two autoidx hashtables into one 
When something calls `IdString::c_str()` on an autoidx ID, we need to cache the
full string in a thread-safe way. If we need to allocate an entry in some data
structure to do that, it's difficult to do in a thread-safe no-performance-hazard way.
So instead, store the cached string pointer in the same hashtable as the prefix
pointer.

Robert O'Callahan 8f0ecce53f Forbid creating IdStrings and incrementing autoidx during multithreaded phases, and add dynamic checks for that 
We could make it safe to increment autoidx during multithreaded passes, but that's
actually undesirable because it would lead to nondeterminism. If/when we need new
IDs during parallel passes, we'll have to figure out how to allocate them in a
deterministic way, and that will depend on the details of what the pass does.
So don't try to tackle that now.

Robert O'Callahan b0e2d75dbe Make IdString refcounts a hashtable containing only the nonzero refcounts 
This saves space and doesn't cost very much since we hardly ever have nonzero refcounts any more.

It also allows for IdStrings with negative indexes, which we're going to add.

Robert O'Callahan 870ae18a2d Switch the SigSpec packed representation to allow just a single chunk that's inline in the SigSpec. 
Single-chunk SigSpecs are very common and this avoids a heap allocation. It also simplifies
some algorithms.
