[PATCH v10 0/7] MR10515: Draft: vbscript: Bind local variables, class properties, and loop variables at compile time.
Resolve identifiers to direct indices during compilation instead of doing runtime `wcsicmp` string scans in `lookup_identifier()`. This adds new opcodes that access local variables, function arguments, class properties, and loop variables by index, eliminating the linear string comparison overhead for the most common cases. **New opcodes:** - `OP_local` / `OP_assign_local` / `OP_set_local` - read/write local vars and args by index - `OP_local_prop` / `OP_assign_local_prop` / `OP_set_local_prop` - read/write class properties by index - `OP_step_local` / `OP_incc_local` - For-loop step/increment with indexed counter - `OP_enumnext_local` - For-Each iteration with indexed loop variable This mirrors jscript's `OP_local` / `bind_local()` optimization (`dlls/jscript/compile.c`) and addresses the FIXME in `lookup_identifier()` noting that class property access should be bound at compile time. Names that cannot be resolved at compile time (globals in Execute/ExecuteGlobal code, dynamic vars, host objects) continue to use the existing string-based path. The last commit also adds a fast path for SAFEARRAY iteration that bypasses the `IEnumVARIANT` COM vtable dispatch and copies elements directly from the array data, eliminating one intermediate `VariantCopy` per iteration. ### Local variable / argument / class property access (1M iterations, 10 reads per iteration) | Benchmark | Windows (VM) | Wine master | Wine (7 commits) | **Speedup** | vs Windows | |-----------|-------------|-------------|-------------------|---------|------------| | Local vars | 156 ms | 10,134 ms | 960 ms | **10.6x** | 6.2x slower | | Arguments | 171 ms | 6,656 ms | 968 ms | **6.9x** | 5.7x slower | | Class props | 265 ms | 6,673 ms | 964 ms | **6.9x** | 3.6x slower | ### For-loop variants (10M iterations) | Benchmark | Windows (VM) | Wine master | Wine (7 commits) | **Speedup** | vs Windows | |-----------|-------------|-------------|-------------------|---------|------------| | Empty For | 117 ms | 6,222 ms | 1,531 ms | **4.1x** | 13x slower | | For + assign | 203 ms | 10,226 ms | 1,710 ms | **6.0x** | 8.4x slower | | Do-While manual | 437 ms | 8,773 ms | 1,820 ms | **4.8x** | 4.2x slower | | For Step 2 | 62 ms | 6,125 ms | 1,527 ms | **4.0x** | 25x slower | | Nested For | 125 ms | 7,742 ms | 1,546 ms | **5.0x** | 12x slower | | For local Sub | 109 ms | 3,062 ms | 1,531 ms | **2.0x** | 14x slower | | For R8 counter | 203 ms | 10,882 ms | 1,492 ms | **7.3x** | 7.4x slower | | For-Each array | 7 ms | 6,339 ms | 58 ms | **109x** | 8.3x slower | The remaining 4-13x gap vs Windows in For-loops is from `VarAdd`/`VarCmp` going through full `VariantChangeTypeEx` machinery (including locale alloc/free per call). A separate MR ([!10528](https://gitlab.winehq.org/wine/wine/-/merge_requests/10529)) adds I2/I4 fast paths in oleaut32 that bring integer loops within 1.2-1.9x of Windows when combined with this branch. -- v10: vbscript: Fast-path For-Each iteration over SAFEARRAY. vbscript: Bind For-Each loop variable at compile time. vbscript: Bind global-scope Dim variables at compile time. vbscript: Bind class properties at compile time. vbscript: Bind For-loop variables at compile time. vbscript: Bind local variable assignments at compile time. vbscript: Bind local variables and arguments at compile time. https://gitlab.winehq.org/wine/wine/-/merge_requests/10515

From: Francis De Brabandere <francisdb@gmail.com> Extend compile-time identifier binding to global-scope code. Previously, bind_local() unconditionally skipped binding for FUNC_GLOBAL functions, forcing every global variable access through the string-based lookup_identifier() path at runtime. Now, for code compiled via ParseScriptText (skip_collisions=FALSE), global Dim variables are bound to indexed slots at compile time, emitting OP_local/OP_assign_local instead of OP_ident/OP_assign_ident. At execution time, exec_script() builds a var_refs[] indirection table that maps compile-time indices to their ScriptDisp->global_vars[] storage. This is done once per script block (O(vars * global_vars)), after exec_global_code() has already registered all Dim variables. Execute/ExecuteGlobal code (skip_collisions=TRUE) is not affected: it still skips binding in bind_local() because the destination of its Dim variables (ScriptDisp vs caller dynamic_vars) is not known at compile time. --- dlls/vbscript/compile.c | 14 ++++++++- dlls/vbscript/interp.c | 66 ++++++++++++++++++++++++++++++++++------- 2 files changed, 69 insertions(+), 11 deletions(-) diff --git a/dlls/vbscript/compile.c b/dlls/vbscript/compile.c index 91b63d41de0..3a614d6f538 100644 --- a/dlls/vbscript/compile.c +++ b/dlls/vbscript/compile.c @@ -64,6 +64,13 @@ typedef struct { function_t *func; function_decl_t *func_decls; dim_decl_t *class_props; + + /* Set for Execute/ExecuteGlobal: (1) suppresses compile-time binding of + * global Dim variables in bind_local(), since they may end up in the + * caller's dynamic_vars rather than ScriptDisp->global_vars; (2) makes + * check_script_collisions() non-fatal so re-declaring an existing name + * is silently tolerated instead of raising VBSE_NAME_REDEFINED. */ + BOOL skip_collisions; } compile_ctx_t; static HRESULT compile_expression(compile_ctx_t*,expression_t*); @@ -491,7 +498,11 @@ static BOOL bind_local(compile_ctx_t *ctx, const WCHAR *name, int *ret) dim_decl_t *dim_decl; unsigned i; - if(ctx->func->type == FUNC_GLOBAL) + /* Execute/Eval code may run from either global or local scope. + * When run from local scope, Dim vars are placed in the caller's + * dynamic_vars, not in ScriptDisp->global_vars.

From: Francis De Brabandere <francisdb@gmail.com> When a For-Each loop iterates over a SAFEARRAY, bypass the IEnumVARIANT COM vtable dispatch and copy elements directly from the array data. This eliminates the COM call overhead and one intermediate VariantCopy per iteration. For non-refcounted element types (VT_I2, VT_I4, VT_R8, etc.), also skip VariantCopyInd and VariantClear entirely, replacing them with a direct struct assignment. Non-SAFEARRAY iterators (e.g. IDispatch collections) continue to use the standard IEnumVARIANT_Next path.
